Surface texturing is an indispensable way of increasing absorption in solar cells. In order to properly characterize the effect of texturing, the angular dependence of the incidence light should be addressed. This is particularly important when the actual application where the incidence angle of the sunlight varies during the day is considered. This study presents the angular dependence of solar cell parameters in the case of periodically textured crystalline silicon (c‐Si) solar cells with microholes. A standard solar cell with pyramid texturing is also studied for comparison. It is shown that the incidence angle for the highest efficiency depends on the surface structure. While a standard pyramid‐textured surface performs best at the zero angle of incidence, it is needed to tilt the sample with microholes textures 15° with respect to the surface normal. This is also confirmed by the simulation study performed for the structures presented in this study.

带有周期性微孔阵列的晶体硅太阳能电池中太阳能电池参数的角度依赖性

表面纹理化是增加太阳能电池吸收的必不可少的方法。为了适当地表征纹理化的效果,应该解决入射光的角度依赖性。当考虑到白天的入射角在一天中发生变化的实际应用时,这尤其重要。这项研究提出了在具有微孔的周期性纹理化晶体硅(c-Si)太阳能电池情况下太阳能电池参数的角度依赖性。还研究了具有金字塔纹理的标准太阳能电池以进行比较。结果表明,最高效率的入射角取决于表面结构。虽然标准的金字塔纹理表面在零入射角下表现最佳,需要将带有微孔纹理的样品相对于表面法线倾斜15°。对本研究中提出的结构进行的模拟研究也证实了这一点。
