AC and DC response of heterojunction a-SiC/c-Si for PV application

Abstract

Interest in amorphous silicon and carbon alloys is always actual mainly due to their particular advantages in comparison to conventional crystalline materials. The amorphous silicon carbide may be used in a number of micro-mechanical and micro-electronics applications and also for photovoltaic energy conversion devices. Boron doped thin layers of amorphous silicon carbide, presented in this paper, were prepared due to the optimization process for preparation of heterojunction solar cell. DC and AC measurement and subsequent evaluation were carried out in order to comprehensively assess the electrical transport processes in the prepared structures.
