The principle and advantage of photovoltaic power generation
Feb 23, 2024 The principle and advantage of photovoltaic power generation
The principle and advantage of photovoltaic power generation Solar photovoltaic power generation principle: Photovoltaic power generation is a technology that converts light energy directly into electrical energy by using the photovoltaic effect of semiconductor interface. The main core components of photovoltaic power generation are solar cells, and other components include batteries, controllers, and so on. Solar cells store sunlight, and then through a series of technical operations to convert its solar energy into electricity, the advantage of this technology is that as long as there is light, solar cells can collect and reserve sunlight. The process of converting solar energy into electricity mainly includes three steps: 1.After the solar cell absorbs a photon of a certain energy, an electron hole pair is generated in the semiconductor, which is called "photogenerated carrier", and the electrical polarity of the two is opposite, the electron is negatively charged, and the hole is positively charged. 2.Photogenerated carriers with opposite electrical polarity are separated by the electrostatic field generated by the semiconductor PN junction. 3.Grid connected pv system, that is, connected to the national grid. China's photovoltaic grid-connected power generation has been very mature, to encourage the conditions of regional industry and commerce and household, public buildings and other construction of photovoltaic power generation facilities, power generation for their own use at the same time can also enjoy the sale of electricity income. Solar photovoltaic power generation systems are mainly used in the following three major aspects: 1.To provide power for non-electric occasions, mainly for the majority of non-electric areas to provide electricity for the living production of residents, microwave relay stations and mobile phone base stations to provide power. 2.Solar daily electronic products, such as all kinds of solar chargers, solar street lights and solar lawn lights. 3.Grid-connected power generation, that is, connected to the national grid. China's photovoltaic grid-connected power generation has been very mature, to encourage the conditions of regional industry and commerce and household, public buildings and other construction of photovoltaic power generation facilities, power generation for their own use at the same time can also enjoy the sale of electricity income. Advantages of solar power: 1.Economic advantage: Solar energy is inexhaustible, and solar energy can generate electricity as long as there is light, which is very convenient; At the current level of technological development, the use of some solar energy has become economical. With the development of science and technology and the breakthrough of human development and utilization of solar energy technology, the economy of solar energy utilization will be more obvious. If the 20th century was the century of oil, then the 21st century is the century of renewable energy (...

Can photovoltaic power stations still generate electricity normally on cloudy or rainy days?
Feb 22, 2024 Can photovoltaic power stations still generate electricity normally on cloudy or rainy days?
Many friends have heard of photovoltaic power generation And know that it relies on light to generate electricity Both environmentally friendly and energy-saving Therefore, the country strongly promotes photovoltaic power plants Since photovoltaic power stations rely on light to generate electricity Then there is no sun on cloudy and rainy days Will our photovoltaic power station stop working? The picture above is a simple power generation diagram of a photovoltaic power station. After reading the picture, many people will ask: Photovoltaic power generation = solar power generation? In fact, there is a difference between them: photovoltaic power generation is only one type of solar power generation, and solar power generation also includes photochemical power generation, light induction power generation and photobiological power generation. Some friends may also ask, will installing photovoltaic power generation produce radiation to the human body? The answer is not only no, photovoltaic power generation can also reflect ultraviolet rays from the sun that are harmful to the human body, so it is very safe and reliable. Can power be generated normally on cloudy or rainy days? First of all, photovoltaic power generation relies on sunlight, and weather changes are crucial to its power generation work. However, on cloudy and rainy days when there is no sun, the photovoltaic power station does not completely stop working. Weak light can also play a certain role in the components. However, in some special cases, the solar radiation is too low, and the operating voltage of the photovoltaic power generation system If the starting voltage of the inverter cannot be reached, the system will not work. Although the photovoltaic power station cannot work hard for us on rainy days, it will not damage the photovoltaic modules. On the contrary, the rain can help us clean the modules. When the sun comes out again, the photovoltaic power station will work even harder to create wealth for you!

Photovoltaic will be like the TV into every household
Feb 21, 2024 Photovoltaic will be like the TV into every household
Television was first invented by the British engineer John Logie Baird in 1925, from the 1980s, television into our families, remember when dozens of people crowded to watch a black and white TV, can not think that now TV is the standard in the family. With the TV on and the news on at 7 p.m., it's a family atmosphere. In recent years, the photovoltaic industry has developed rapidly, and the installation of photovoltaic has become a representative of fashion trends. If you installed photovoltaic on your roof a few years ago, and even local media came to interview, an interview became famous, and then everyone came to the home to see the photovoltaic roof built, quite the first village to buy a TV set, the whole village came to your home to watch TV feeling. So why say that photovoltaic in the future will become the standard of every household? This starts from the rapid development of photovoltaic power generation in the past two years, in recent years, the state has issued many policies to support the photovoltaic industry, carbon peak carbon neutral and double carbon targets have greatly promoted the development of the photovoltaic industry, at the same time the rapid development of our economy, China is facing more and more environmental pressure, and the construction of distributed photovoltaic is one of the most effective ways to reduce environmental pressure. Distributed photovoltaic construction on the industrial and commercial roofs or residential roofs, does not occupy additional resources, close to the power end, is one of the most important forms of power generation in the future, each household can produce electricity, into the grid, using "self-use surplus electricity online" or "full Internet" mode. It has not only made great contributions to the national green strategy, but also increased the income of individuals or enterprises, so that there is no harm in it, and it is inevitable that it will become the standard of every household in the future. Simple maintenance Many owners are wondering that as a photovoltaic roof as a power generation equipment, is it really noise-free, pollution-free and radiation-free? Photovoltaic power stations use solar energy for photoelectric conversion, and are very safe to install on the roof. And there is no loss in the power generation process, it can be used for 25 years, and the attenuation is less than 20% after 25 years. The radiation of photovoltaic compared with household appliances is about the same as that of laptop computers, lower than induction stoves, hair dryers, refrigerators. So there's no need to worry about it.

Battery materials market facing oversupply and macroeconomic headwinds in 2024 | 2024 preview
Feb 20, 2024 Battery materials market facing oversupply and macroeconomic headwinds in 2024 | 2024 preview
Fastmarkets looks ahead to 2024 and beyond at some key developments for the battery materials market as the clean energy transition faces a challenging global economic and geopolitical backdrop. By the Fastmarkets team 2024 outlook; Automotive; Battery materials; Electric vehicles; Supply chains In recent years the fundamental drivers of battery demand and battery raw material supply have been largely immune to global macroeconomic fluctuations. This changed in 2023, as growing economic headwinds began to weigh on consumer sentiment. Whilst electric vehicle (EV) sales remained robust, they could not match the exceptional year-on-year (YoY) growth rates observed in recent years. Excess EV production capacity, a buildup of inventory and destocking by cathode producers resulted in thin demand for battery materials. This coupled with upstream expansions and market oversupply led to a notable softening of battery raw material prices in 2023. So, what does this year ahead have in store? EV growth to slow further in 2024 We believe EV sales will remain on a steady upwards trajectory in 2024, albeit with a lower (23%) YoY growth rate forecast than in 2023 (36%), as the uncertain economic climate, particularly relatively high interest rates, continue to weigh on buyers’ decisions. This will be particularly true in markets such as the US, where vehicle financing plays a pivotal role in consumer purchases. The end of 2023 saw a scale back in EV production forecasts from some of the major western automakers. As EV sales continue to underperform relative to expectations in Europe and the US, we anticipate further delays or slowing of EV factory ramp-up in 2024. Lithium supply response charges ahead of demand Supply additions from restarts, expansions and greenfield projects started in 2022, with rapid supply increases in China. This caused the market to swing from a supply deficit to a surplus in 2023. Looking forward to 2024, we are now in a situation where some new supply is being ramped up while some high-cost production is being cut. Fastmarkets expects lithium supply to increase by 30% in 2024. However, we await to see the impact the current price environment will have on supply, as some producers may choose to reduce production or delay expansions. Furthermore, whilst Chinese production seems less prone to suffering delays – as seen with the ramp-up of domestic lepidolite and African spodumene projects, in most cases we expect new capacity to experience some start-up delays, contributing to supply-side risk. Market participants expect downstream lithium demand to remain relatively weak and with no imminent concerns about supply shortages, we forecast a tentatively balanced market in 2024. We believe we are approaching the bottom of the market, considering the industry is moving fairly deep into the cost curve. This is likely to support lithium prices as producers consider further production cuts to balance the market and stem further losses. Considering...

Unpacking Hydrogen’s Role in Decarbonizing Electricity Sector
Jan 30, 2024 Unpacking Hydrogen’s Role in Decarbonizing Electricity Sector
Hydrogen’s Role in Decarbonizing the Electricity Sector Hydrogen constitutes 75% of the elemental mass in our universe. According to the International Energy Agency (IEA), it could also play a pivotal role in global decarbonization efforts.This infographic, created in partnership with the National Public Utilities Council, explores three ways this element could support the decarbonization of the global electricity sector. Hydrogen 101 First, let’s get a few basics about hydrogen out of the way.While abundant in nature, hydrogen is rarely found in its elemental state (H2) on Earth, meaning that it needs to be separated from other chemical compounds, such as water (H2O). Once extracted, however, it becomes a versatile and energy-dense fuel source, containing approximately three times the energy content of gasoline or natural gas.There are several methods to extract hydrogen from compounds. Depending on the production method and energy source, the resulting hydrogen is often categorized by color to show its emission impact. Today, black, gray, and blue hydrogen are used in emission-heavy industries such as petroleum refining and ammonia production. The technology and infrastructure for purple and green hydrogen, on the other hand, are still taking shape. As they progress, these emission-free sources of hydrogen are expected to play a pivotal role in decarbonizing many hard-to-abate sectors, including power. Three Ways Green Hydrogen Can Help Decarbonize Now that we’ve covered hydrogen basics, let’s dive into where emission-free hydrogen can fit in the race to decarbonize our global electricity system. #1: Hydrogen and Natural Gas Blending Hydrogen can be blended with natural gas in existing pipeline infrastructure for lower-emission power generation.According to Jenbacher, a 20–30% hydrogen volume can lead to a 7–11% decrease in CO2 emissions, compared to natural gas on its own. In 2022, U.S. electricity from natural gas generated 743 million metric tons in the United States. A 9% reduction in emissions through hydrogen blending lowers emissions by 67 million metric tons CO2, all without the need to build new infrastructure. #2: Fuel Cells A fuel cell generates electricity through an electrochemical reaction between hydrogen and oxygen, with water as the only byproduct. By using green or pink hydrogen, fuel cells can provide 100% emission-free electricity that is also efficient, reliable, and dispatchable. #3: Energy Storage Energy storage plays a pivotal role in decarbonizing the power sector by balancing the intermittent nature of renewables.While other technologies, such as lithium-ion batteries, can also provide energy storage, hydrogen has a greater potential to offer both large-scale and long-term storage, up to several months at a time.As technology advances, the IEA predicts that global underground hydrogen capacity will grow by more than 200,000% in the next 30 years, reaching 1,200 TWh in 2050. That amount of energy can power 70,000 U.S. h...
