solar cell materials
Photovoltaic materials, also known as solar cell materials, refer to materials that can directly convert solar energy into electrical energy. Photovoltaic materials can generate current because of the photovoltaic effect, that is, if light shines on the solar cell and the light is absorbed in the interface layer, photons with sufficient energy can excite electrons from covalent bonds in P-type silicon and N-type silicon , So as to produce electrons.
