摘要
In this paper, we report the progress of nanocrystalline silicon (nc-Si) based a-Si/nc-Si double-junction solar cell technology development at Hanergy Solar. We conduct the experiments mainly for optimization and development on 1) high quality intrinsic amorphous silicon (a-Si) films used for top cells, 2) p-Iayers and buffer layers, and 3) intrinsic nc-Si film used for bottom cells. We have achieved initial total area efficiency of 12.9%, and stable total area efficiency of 11.1 % for a-Si/nc-Si double-junction modules (0.79m(2)). Experimental results including study of individual component cell optimization, crystal volume fraction optimization, and development of superior doped layers are presented.
