The influence of realistic interface morphologies on light trapping in amorphous silicon thin-film solar cells with periodic surface textures is studied. Realistic interface morphologies are obtained by a 3D surface coverage algorithm using the substrate morphology and layer thicknesses as input parameters. Finite difference time domain optical simulations are used to determine the absorption in the individual layers of the thin-film solar cell. The influence of realistic interface morphologies on light trapping is determined by using solar cells structures with the same front and back contact morphologies as a reference. Finally the optimal surface textures are derived.
研究了具有周期性表面纹理的非晶硅薄膜太阳能电池中实际界面形态对光捕获的影响。通过使用衬底形态和层厚度作为输入参数的三维表面覆盖算法获得实际界面形态。采用时域有限差分光学模拟来确定薄膜太阳能电池各层中的吸收情况。通过使用具有相同前后接触形态的太阳能电池结构作为参考，确定实际界面形态对光捕获的影响。最后得出最佳表面纹理。
