Introduction to Solar Cells

A solar cell is a photoelectric semiconductor sheet that uses sunlight to generate electricity directly, also known as a "solar chip" or "photovoltaic cell". generate current. In physics, it is called solar photovoltaic (Photovoltaic, abbreviated as PV), referred to as photovoltaic.
A solar cell is a device that directly converts light energy into electrical energy through the photoelectric effect or photochemical effect. Crystalline silicon solar cells that work on the photovoltaic effect are the mainstream, while thin-film solar cells that work on the photochemical effect are still in their infancy.
On February 28, 2023, the National Bureau of Statistics released the "Statistical Bulletin of the People's Republic of China on National Economic and Social Development in 2022". The report shows that the annual output of solar cells (photovoltaic cells) in 2022 will be 340 million kilowatts, an increase of 46.8%. In the first quarter of 2023, China's solar cell exports exceeded 90 billion yuan, an increase of 23.6%.
