Unlocking the potential of MgF2 textured surface in enhancing the efficiency of perovskite solar cells

In this work, we explored the use of magnesium fluoride (MgF2) based textured surfaces in perovskite solar cells (PSCs) to enhance light trapping and increase conversion efficiency. We studied the impact of different positions of random pyramid arrays (RAs) on reflectance, EQE, JV curve, and PV parameters. Our results showed that this approach led to a conversion efficiency of 24.8% with JSC of 26.12 mA/cm2.
