Perovskite Solar Cells (PSC) have been elicited much interest within the photovoltaic industry due to their many performance advantages. One of the effective ways to enhance the Power Conversion Efficiency (PCE) of PSCs is to minimize light and electrical losses. To this end, we have focused on the use of nanostructured light absorbers in PSCs and have simulated these structures to understand their effects on the light absorption and electrical output of the cells. Given that perovskites do not absorb light of wavelengths higher than 800 nm, we used an extra absorption material - GeSe – which has a narrower bandgap and a wider absorption spectrum in order to increase the amount of light absorbed. GeSe Nano-pyramids (GSNPs) were also used in the active layer (perovskite) to manage input light. The use of such structures improved the short-current density (J_sc) of the cell. The effects of changing the height of GeSe NPs were also investigated to determine the best height of NPs that produced the highest PCE. The optimal structure had NP height of 100 nm and resulted in J_sc and PCE values of 24.83 mA/cm² and 18.49%, respectively, which were 25.65% and 21.80%, improvements over the planar design, respectively.

钙钛矿太阳能电池（PSC）由于其许多性能优势而引起了光伏行业的极大兴趣。增强PSC的功率转换效率（PCE）的有效方法之一是最大程度地减少光和电损耗。为此，我们集中研究了纳米结构光吸收剂在PSC中的使用，并模拟了这些结构以了解其对电池的光吸收和电输出的影响。考虑到钙钛矿不能吸收波长大于800 nm的光，我们使用了一种额外的吸收材料GeSe，该材料具有较窄的带隙和较宽的吸收光谱，以增加吸收的光量。GeSe纳米金字塔（GSNP）也用于活性层（钙钛矿）中以管理输入光。_sc）。还研究了改变GeSe NP高度的影响，以确定产生最高PCE的NP的最佳高度。最佳结构的NP高度为100 nm，其J _sc和PCE值分别为24.83 mA / cm ²和18.49％，分别比平面设计提高了25.65％和21.80％。
