Suitability of LBSO/CuI as an Effective ETL/HTL for Perovskite Solar Cells: A Dry Lab Approach
With rapid breakthroughs in power conversion efficiency (PCE), hybrid halide perovskites (HHPs) based solar cells have been considered as the potential candidates for the next generation solar cell technology. However, these perovskite solar cells (PSCs) are still far from the door of the photovoltaic market owing to their instability issue involved with various used materials during fabrication. In this work, we deal with the numerical simulation of PSC devices via SCAPS-1D software. For better performance, several prominent materials for absorber layer have been proposed with a combination of La-doped BaSnO3 as ETL and CuI as HTL. The strong dependency of proper ETL, absorber layer and HTL on the overall device performance has been observed. Moreover, the FAPbI3-based device outperformed other devices with different absorber materials, yielding an overall PCE of 22.09 %. Thus, the dry lab approach using computer simulations will be helpful for experimentalists to design and fabricate similar PSCs by reducing the cost of experimental trials.
