Solar cells, also known as "solar chips" or "photocells", are photoelectric semiconductor sheets that use sunlight to directly generate electricity. As long as it is exposed to light that meets certain illuminance conditions, it can instantly output voltage and generate current when there is a loop. In physics, it is called photovoltaic (Photovoltaic, abbreviated as PV), or photovoltaic for short.
Solar cells are devices that directly convert light energy into electrical energy through photoelectric effect or photochemical effect. Crystalline silicon solar cells that work with the photovoltaic effect are the mainstream, while the implementation of solar cells with thin-film cells that work with the photochemical effect is still in its infancy.
