CdTe-based thin film photovoltaics: Recent advances, current

CdTe thin film solar cells grew out of these II-VI semiconductor beginnings, in-parallel with CdS efforts at General Electric and the US Air Force, as Loferski [52] had realized that the CdTe bandgap was well-matched to the solar spectrum. Also, CdTe could be doped both n- and p-type – a factor that has not received as much attention in the PV context.
