Glass-Si heterojunction solar cells

Abstract

Experimental studies and models for In2O3/Si and SnO2/N-Si solar cells are considered for their suitability in terrestrial applications. The silicon is the active material, and the glass serves as the window to solar radiation, an antireflection coating of the Si, and a low resistance contact. Results show that amorphous windows or layers suppress photocurrent. The interfacial SiO2 layer suppresses photocurrent and increases series resistance. Suppression increases with illumination.
