A high efficiency thin film silicon solar cell and module

Advanced light trapping management by diffractive interlayer for thin-film silicon solar cells

“…1,2 The use of intermediate reflector layers is a promising approach to control light in multijunction solar cells. [3][4][5] Apart from varying the thicknesses of the two absorber layers, it is also possible to adjust the current matching by integrating an intermediate reflector ͑IR͒. This is of special interest, because amorphous silicon films suffer from the Staebler-Wronski degradation.…”

Asymmetric intermediate reflector for tandem micromorph thin film silicon solar cells

“…9͒ have been reported to be very effective and are already implemented in complete products. 10 Nonetheless in the substrate configuration ͑n-i-p͒ useful for opaque substrate, the problem of high efficiency micromorph tandems with elevated J sc in the top cell is not yet solved because of the difficulties involved in obtaining high J sc in both subcell components. The solution so far has been triple junction solar cells with low band gap a-SiGe where the absorption is distributed into three thin cells.…”

Study on Crystalline Volume Fraction and Activation Energy for Silicon Thin Film Prepared by VHF-PECVD

“…At present, at home and abroad are very concerned about the study of microcrystalline silicon thin film solar cells, mainly concentrated in the United Solar of United States [1] , Kaneka Corporation of Japan [2], Julich photovoltaic research institute of Germany [3], Utrecht University of Netherlands [4], IMT Institute of Swiss [5] and Optoelectronic Thin Film Device and Technology Research Institute of Nankai University in china [6].The very high frequency plasma chemical vapor deposition (VHF-PECVD) technique can be well compatible with conventional RF-PECVD technique, so microcrystalline silicon film preparation is widely concerned and has made great progress in the research.…”
