钙钛矿硅串联太阳能电池结合了潜在的低生产成本和超越硅单结太阳能电池效率极限的能力。光学建模和优化对于在不久的将来实现这一雄心勃勃的目标至关重要。优化应寻求基于实际环境条件的能量产出最大化。本文基于实际实验数据分析了钙钛矿硅串联太阳能电池和组件的能量产量，重点研究了太阳能电池前后侧的表面纹理及其对反射和寄生吸收特性的影响。根据2014年德国弗莱堡的辐照度数据，与封装的高效单结太阳能电池相比，具有纹理前端的封装串联电池的能量产量提高了7.3%，收获效率为24.3%。
Perovskite silicon tandem solar cells combine potentially low production costs with the ability to surpass the efficiency limit of silicon single junction solar cells. Optical modeling and optimization are crucial to achieve this ambitious goal in the near future. The optimization should seek to maximize the energy yield based on realistic environmental conditions. This work analyzes the energy yield of perovskite silicon tandem solar cells and modules based on realistic experimental data, with a special focus on the investigation of surface textures at the front and rear side of the solar cell and its implication for reflection as well as parasitic absorption properties. The investigation reveals a 7.3%rel higher energy yield for an encapsulated tandem cell with a textured front side compared with an encapsulated high efficiency single junction solar cell with 24.3% harvesting efficiency for irradiance data of the year 2014 in Freiburg/Germany.
