However, this would only be possible by using wide-band-gap semiconductors, which have not been considered for solar cells used for land-based applications because their band gaps are too large.

Techniques for Band Gap Engineering vary, including doping, the introduction of impurities into a semiconductor to alter its electrical properties; strain engineering, where stress is applied to ...
