ABSTRACTThis paper reviews recent progress in large-area a-Si/a-SiGe tandem solar cells in Sanyo. Much effort has been devoted to increasing both the stabilized efficiency and the process throughput. A key issue in increasing the stabilized efficiency is thinner i-layer structure with an improved optical confinement effect. High-rate deposition of the i-layers has been investigated using rf (13.56MHz) plasma-CVD method while keeping the substrate temperature below 200 °C. A high photosensitivity of 106 of a-Si:H films maintain up to the deposition rate (Rd) of 15 Å/s by optimizing hydrogen dilution and other deposition conditions. It is of great importance to utilize the effect of hydrogen dilution which can reduce the incorporation of excess hydrogen in the films. The world's highest conversion efficiency of 11.2% has been achieved for a large-area (8252cm2) a-Si/a-SiGe tandem by combining the optimized hydrogen dilution and other solar cell related technologies.

ABSTRACTWe report a study of a-Si:H/a-SiGe:H dual-bandgap p-i-n type tandem solar cells and Modules. Refined bandgap grading in the a-SiGe:H bottom cell results in higher Jsc (higher red response) without loss in FF or Voc. IMprovements in the tunnel junction consisting of doped widegap a-SiC:H and μC-Si lead to higher FF and lower optical loss. Undoped widegap a-SiC:H is used as interface layers in the top junction. Initial conversion efficiencies of 11.4% and 10.5% have been obtained for small-area cells and one-square-foot modules, respectively. The double junction cells and modules exhibit good stability and saturation of light-induced degradation, showing only ∼15% decrease in conversion efficiency after more than 1000 hours of simulated AM1.5 illumination. The stabilized efficiencies are 9.6% and 9.1%, respectively, for small area cell and large area Module. We also present some findings from the computer simulations of multijunction solar cell performance using a simple lump-circuit device Model.
