Photovoltaic solar cells (called photovoltaic cells) are used to directly convert solar energy into electrical energy. Currently, most photovoltaic systems use monocrystalline silicon, crystalline silicon, and amorphous silicon solar cells. performance such as energy conversion efficiency and service life. Surface monocrystalline silicon cells are better than amorphous silicon cells. Crystalline silicon has lower conversion efficiency than single crystal silicon and is cheaper.
Can single crystal germanium be used as a photoelectric conversion material. for solar cells?
Please describe the problem in detail
Different doping elements, different conductivity types and different applications.
1. Different doping elements: p-type germanium materials contain impuritiesBoron materials and n-type germanium materials contain phosphorus impurities.
2. Different types of conductivity: In the manufacturing of semiconductor devices, high-purity p-type and n-type germanium often need to be doped to become pn-junction semiconductor materials.
3. Different applications: high purity p-type germanium can be used as a material for solar cells, pyroelectric components, detectors and other devices, and high purity n-type germanium can be used as a material. deoxidizer in the preparation of monocrystalline silicon, wait.
