A multi-component solar cell refers to a solar cell that is not made of a single element semiconductor material. Nowadays, there are many varieties of research in various countries, most of which have not been industrialized, mainly including the following: a) cadmium sulfide solar cells b) gallium arsenide solar cells c) copper indium selenide solar cells (new multi-band gap gradient Cu (In, Ga) )Se2 thin film solar cell) Cu(In, Ga)Se2 is a kind of solar absorbing material with excellent performance. It has a multi-layer semiconductor material with gradient energy band gap (the energy level difference between conduction band and valence band), which can expand the solar absorption spectrum range and improve photoelectric conversion. effectiveness. Based on it, a thin film solar cell with a significantly higher photoelectric conversion efficiency than a silicon thin film solar cell can be designed. The photoelectric conversion rate that can be achieved is 18%. Moreover, such thin film solar cells have not been found to have a performance degradation effect (SWE) due to optical radiation, and the photoelectric conversion efficiency thereof is improved by about 50~ compared with the current commercial thin film solar panels. 75% is the world's highest level of photoelectric conversion efficiency in thin film solar cells.
