The working principle of amorphous silicon solar cells is similar to that of crystalline silicon solar cells. Both use the photovoltaic effect of semiconductors to convert sunlight energy into electrical energy. When sunlight shines on amorphous silicon materials, photons are absorbed by amorphous silicon materials to generate electron-hole pairs. These electrons and holes are separated under the action of the electric field inside the semiconductor to form current and voltage.
2. Structural Materials
Amorphous silicon materials: Amorphous silicon is a semiconductor material with a disordered structure. Compared with crystalline silicon, its atomic arrangement has no obvious periodicity. The bandgap width of amorphous silicon is wider than that of crystalline silicon, which makes it absorb sunlight in a wider range and can absorb more visible light and infrared rays.
