Solar cell, is a direct use of sunlight to generate electricity photoelectric semiconductor wafer, also known as "solar chip" or "photocell", as long as it is met with a certain illuminance conditions, instant output voltage and in the case of a loop current. In physics, it is called solar Photovoltaic (PV), or photovoltaic for short.
Solar cells are devices that convert light energy directly into electricity through photoelectric or photochemical effects. The photovoltaic effect of crystalline silicon solar cells is the mainstream, and the photochemical effect of thin film cells to implement solar cells is still in the embryonic stage.
On February 28, 2023, the National Bureau of Statistics released the "Statistical Bulletin of the People's Republic of China 2022 National Economic and Social Development", which showed that the annual output of solar cells (photovoltaic cells) in 2022 was 340 million kW, an increase of 46.8%. [4] In the first quarter of 2023, China's solar cell export exceeded 90 billion yuan, an increase of 23.6% .
