Abstract
Optimal light management in perovskite solar cells (PSCs) is very crucial to increase the photon absorption and overall performance of the device. In the present study, an MgF2 textured front surface has been applied to the PSCs followed by the optimization of different parameters including pyramid angle (54°–55°), offset (0–1 μm), and refractive index of textured surface (1.4–2.0). The presence of a textured surface with optimized parameters of pyramid angle (54.4°), offset (0 μm), and reflective index (1.4) resulted in an enhanced photogeneration rate and short circuit current density (JSC) 26.24 mA cm−2 with remaining photovoltaic (PV) parameters: open circuit voltage (VOC) 1.228 V, fill factor (FF) 77.86 % and power conversion efficiency (PCE) 25.10 %. All the PSC devices are analyzed with the help of the current density voltage curve (J-V), external quantum efficiency (EQE), photogeneration rate, and optical intensity profile within the device structure. The proposed front surface design may pave the way for the efficient utilization of optical spectrum and for the development of advanced high-efficiency PSC.
