Abstract

Amorphous InZnO (a-IZO) thin film transparent conductors have opto-electronic properties comparable to those of indium-tin-oxide (ITO). To test the performance of a-IZO in actual devices, we fabricate epitaxial film c-Si/a-Si heterojunction solar cells on heavily doped, electronically dead silicon wafers using both a-IZO and reactive evaporated ITO as the transparent conducting oxide (TCO). The best a-IZO and ITO reference solar cells have similar efficiencies, 6.2% for the a-IZO device and 6.0% with ITO.
