CIGS Photovoltaics

Using both sides of the panel

Bifaciality allows the harvest of sunlight from both sides of a solar cell and thereby increases power output, but the efficiency of thin-film devices lags behind that of silicon counterparts. Now, researchers demonstrate a bifacial Cu(In,Ga)Se2-perovskite tandem solar cell with a 28 mW/cm2 power output under front and rear illumination.
