CdTe performance could be increased with chlorine
According to a team of researchers from Loughborough University (UK), it is possible to increase the efficiency of cadmium telluride (CdTe) cells by using chlorine. This product could deactivate
the electron trap and make the grain boundaries less active. Chlorine eliminates stacking defects. First Solar's laboratory efficiency is 22.1%. This could be increased to 25%.
According to the university, 25 GW of CdTe panels have been installed worldwide and 5.5 GW by 2020, with a lower manufacturing cost than silicon-based panels
20% of the panels installed in the US are CdTe based
