Abstract

The optical characteristics used in the photovoltaics of nano- and microstructure, evaluated using electromagnetic radiation transfer computation software, mismatch with data obtained at high estimated times. The ability to apply the geometric optics approximations is shown for this purpose. Relevant computations using a 3D ROKS-RG programming tool (the Monte Carlo method) are performed for various experimental results on the optical parameters of nano- and microstructures available in the scientific literature. Given that surface roughness exists as a byproduct of etching during the preparation of structures, the theory is found to satisfactorily agree with experiment. Moreover, most of the radiation is absorbed on account of the surface roughness of substrates, which is expected to induce a nonuniform charge carrier distribution over the structure height and may be among the reasons for the insufficiently high efficiency of solar elements with radial p–n geometry.

应用几何光学技术来计算光伏器件中的纳米和微结构的可能性

摘要

使用电磁辐射传输计算软件评估的纳米和微结构光伏电池中使用的光学特性与在高估计时间获得的数据不匹配。为此显示了应用几何光学近似的能力。使用3D ROKS-RG编程工具（蒙特卡罗方法）进行了相关计算，以获取有关科学文献中可用的纳米和微观结构的光学参数的各种实验结果。考虑到表面粗糙度是在结构制备期间作为蚀刻的副产物而存在的，因此发现该理论与实验令人满意。此外，由于基材的表面粗糙度，大部分辐射被吸收，p–n几何。
