CIGS Thin Film Solar Cell Module


CIGS thin film solar cell module has a light absorbing layer made of Cu(In1-xGax)Se2 (CIGS)compound. The module conversion efficiency is over 13% with the commercial products and has reached 15% with prototype. The cell including the CIGS layer is formed on a large glass substrate by sputtering technology. For this reason it is relatively easy to produce a large-area module. And the effect of partial shade on the module to decrease the power generation is lower than crystalline silicon.


Provides a CIGS thin film solar cell module with module conversion efficiency 15%.
