| More Details: | Perovskite solar cells (PSCs) are in the focus of the photovoltaic industry. Lead-free double perovskite solar cells (DPSCs) have become an essential alternative of lead-based PSCs as a promising photovoltaic material. The double perovskite layer is a remarkable choice as active layer because of intrinsic carrier stability, low exciton binding energy, and low toxicity. Herein, the optimization of a planar DPSC with a multifunctional double perovskite absorber layer, that is, La2NiMnO6 (LNMO), is studied with the organic and inorganic hole transport layers (HTLs) Cu2O and PEDOT:PSS. Our study yields a significant improvement in the power conversion efficiency (PCE) of perovskite solar cells with two types of HTLs. The optimized devices achieved a maximum PCE of 27.84% and 27.38% for Cu2O and PEDOT:PSS, respectively, with corresponding open-circuit voltages of 1.27 and 1.22 V, short-circuit current densities of 28.60 and 28.91 mA/cm2, and fill factors of 76.31% and 77.15%, respectively. These results highlight the potential of these HTLs for enhanced device performance. |
