Solar Cell

It is a kind of photoelectric semiconductor chip that uses sunlight to generate electricity directly, also known as "solar chip" or "photocell". As long as it is satisfied with certain illumination conditions, it can instantly output voltage and generate current in the case of circuit. In physics, it is called solar photovoltaic (PV for short).
Solar cells are devices that directly convert light energy into electricity through photoelectric or photochemical effects. Crystalline silicon solar cells working with photovoltaic effect are the mainstream, while thin film cells working with photochemical effect are still in the embryonic stage of implementing solar cells.
On February 28, 2023, the National Bureau of Statistics released the Statistical Bulletin of the National Economic and Social Development of the People's Republic of China in 2022. The report showed that the annual output of solar cells (photovoltaic cells) in 2022 was 340 million kilowatts, an increase of 46.8%.
