Influence of Ga content on defects in CuInxGa1-xSe2 based solar cell absorbers investigated by sub gap modulated photocurrent and admittance spectroscopy

In this work, we investigate the influence of gallium content on the defects properties of co-evaporated CuInxGa1 − xSe2 by subgapmodulatedphotocurrentspectroscopy and admittancespectroscopy techniques. A series of CuInxGa1 − xSe2basedsolarcells with different gallium content in the range from 0% to...
