Polycrystalline silicon thin film solar cells on glass

Poly Si thin film solar cells on glass feature the potential to reach single junction efficiencies of 15 or even higher at low costs. In this paper innovative approaches are discussed which could lead to substantial efficiency improvements and significant cost reductions i Preparation of large grained poly Si films using the seed layer concept targeting at high material quality. ii Utilization of ZnO Al coated glass enabling simple contacting and light trapping schemes. iii Utilization of high rate electron beam evaporation for the absorber deposition offering a high potential for cost reductio
