采用Afors-het太阳能电池异质结模拟软件, 模拟了不同工作温度下, 微晶硅窗口层对μc-si(p)/c-si(n)/μc-si(p+)异质结太阳能电池性能的影响, 结果表明: 随着微晶硅窗口层帯隙的增加, 转化效率先增加后下降、开路电压不断增加; 掺杂浓度的增加, 电池性能整体呈现先上升后小幅下降的趋势; 厚度的增加, 电池的性能整体上呈现下降的趋势。随着工作温度的增加, 微晶硅窗口层对应的最佳厚度和掺杂浓度值都有明显的减小趋势; 但其对应的最佳帯隙有明显的增加的趋势。该实验结果为在不同温度下工作的电池提供了商业化生产的实验参数。

The influence of window layer of microcrystalline silicon on the μc-si(p)/c-si(n)/μc-si(n+) heterojunction solar cell is simulated with Afors-het software at different operation temperatures. It is shown that the conversion efficiency increases first and then decreases and the open circuit voltage raises with the increasing of the band gap of Microcrystalline silicon window layer. The cell performance rises at first and then drops slightly with the doping concentration increases. The overall performance of the battery shows the tendency of decline when the thickness is increased. The trend of decrease is obviously shown with the increase of operation temperature, the optimal thickness and doping concentrations corresponding to the Microcrystalline silicon window layer. However, the correspond best band gap increase clearly. The experimental parameters for commercial production of battery working under different temperature are thus provided.
