摘　　要：报道了对p n型GaInP2 GaAs叠层太阳电池的研究结果 .采用低压金属有机物化学气相沉积工艺制备电池样品 .通过对GaInP2 顶电池中场助收集效应的计算机模拟 ,提出用p+ p- n- n+ 结构取代常用的p+ n结构 ,显著改善了GaInP2 顶电池和GaInP2 GaAs叠层太阳电池的光伏性能 ,使其光电转换效率 (Eff)分别达到 14 2 6 %和 2 3 82 %(AM0 ,2 5℃ ,2× 2cm2 )This paper reports the study on p-n GaInP 2/GaAs tandem cells. The cell samples were produced by metal_organic chemical vapor deposition at a low gas pressure. In order to optimize the device configuration, numerical modeling has been performed for the impacts of a field-aided collection on the performances of the top cells. On the basis of modeling results, a modified configuration of top cells is introduced, using p +-p --n --n + structure instead of p +-n structure. This modification has brought about much improved photovoltaic performance of the top and tandem cells, with the conversion efficiency Eff=14.26% and 23.82% (AMO, 25℃, 2×2cm 2), respectively.
