Description
technical field [0001] The present application relates to solar cell modules. Background technique [0002] A compound semiconductor is not made of a single element such as silicon (Si) and germanium (Ge), but is formed of a combination of two or more elements to function as a semiconductor. Currently, various compound semiconductors have been developed and used in various fields. Compound semiconductors are generally used in light-emitting elements such as light-emitting diodes and laser diodes, solar cells utilizing the photoelectric conversion effect, thermoelectric conversion elements utilizing the Peltier effect, and the like. [0003] Compound semiconductor solar cells use compound semiconductors in a light absorbing layer that absorbs sunlight and generates electron-hole pairs. The light absorbing layer uses III-V compound semiconductors such as GaAs, InP, GaAlAs and GaInAs, II-VI compound semiconductors such as CdS, CdTe and ZnS, such as CuInSe 2 I-III-VI compound...
