摘要：

In the effort to increase the stable efficiency:of thin film silicon micromorph solar cells, a silicon oxide based, intermediate reflector (SOIR) layer is deposited in situ between the component cells of the tandem device. The effectiveness of the SOIR layer in increasing the photo-carrier, generation in the a-Si:H top absorber is compared for p-i-n devices deposited on different rough, highly transparent, front ZnO layers. High haze and low doping level for the front ZnO strongly enhance. the current, density (J(sc)) in the mu c-Si:H bottom cell whereas J(sc) in the top cell is influenced by the angular distribution of the transmitted light and by the reflectivity of the SOIR related to different, surface roughness. A total J(sc) of 26.8 mA/cm(2) and an initial conversion efficiency of 12.6% are achieved for 1.2 cm(2) cells with top and bottom cell thicknesses of 300 nm and 3 mu m, and without any anti-reflective coating on the glass.
