Cadmium telluride solar cell based on indium gallium oxide emitter achieves 17.2%

Developed by the University of Toledo, the cell achived the highest efficiency ever reported for flexible cadmium telluride solar cells to date. The device reached an open-circuit voltage of 861 mV, a short-circuit density of 27. 8 mA/cm2, and a fill factor of 71. 7%. Researchers from the University of Toledo in the United States have developed a flexible cadmium telluride (CdTe) solar cell based on an indium gallium oxide (IGO) emitter layer and a cadmium stannate (CTO) transparent conductor as the front electrode. "A sputtered cadmium selenide (CdSe) layer was employed to incorporate Se into ...
