摘要：

The performance of multijunction amorphous silicon-based thin film solar cells has been reported using thin layers of TiO2 and SiOx acting as refractive index matching optical layers for different interfaces of the superstrate device structure. Improvement of short-circuit current from the sub-cells of a-Si/mu c-Si cells is demonstrated with TiO2 as anti-reflection layer at TCO/Si interface and SiOx as intermediate-reflector layer between two sub-cells. An initial efficiency of 11.8% is achieved by applying both the TiO2 and SiOx optical layers in a-Si/mu c-Si solar cell. (C) 2009 Elsevier B.V. All rights reserved.
