Abstract
To efficiently transform light energy into electrical via developing smart and environmentally benign materials is one of the most investigated ways of producing renewable energy. Here, inorganic-lead free and non-toxic double perovskite La2NiMnO6 material is employed as an active layer along with fullerene as ETL and NiO as HTL to form heterostructure perovskite solar cell. To determine the highest power conversion efficiency for the current photovoltaic device, an extensive theoretical analysis is implemented using the SCAPS-1D simulation tool. The best performing devices showed power conversion efficiency of 24.46% with excellent solar cell characteristics, whereas the performance can be tuned via careful modulation of metal work function. The theoretical finding suggests that with a systematic investigation of these materials can be utilized as probable successors for highly efficient active material in photovoltaic utilities.
