The etching and annealing influences of front-contact ZnO:Ga on amorphous thin film silicon solar cells

Abstract

For achieving higher performance of amorphous silicon thin film solar cell, the front-contact ZnO:Al is needed to be concerned. In this paper, we focus on how the front contact ZnO:Al influences the a-Si:H thin film solar cell. In order to understand the relationship between the front-contact ZnO:Al and device, we establish a model to simulate how the feature size of the textured ZnO:Al influence the haze and short-circuit current. Moreover we introduce the anneal effect on a-Si:H thin film solar cell.
