Abstract

A solar cell is a device that uses the photovoltaic effect to convert light energy into electricity, producing an electrical charge that can move freely in a semiconductor. High -performance solar cells nowadays are first generation solar cells that are mostly based on silicon wafers. Silicon has several advantages over other competitive materials, but ultra -pure semiconductor wafers are indeed expensive in terms of finance and energy. However, the third-generation solar cell, perovskite solar cell (PSC) has come a long way and has produced a lot of high-quality work, in contrast to silicon solar cells, perovskite solar cells (PSCs) are inexpensive. The electron transport layer (ETL) plays an important role in the photovoltaic performance and overall stability of perovskite solar cells. This project proposes the potential of SnO2 as an ETL in perovskite solar cell (PSC) applications. Lanthanum is doped together with SnO2 as an electron transport layer (ETL) to obtain solar cell parameter results in terms of efficiency and fill factor (FF), designed and simulated in wxAMPS software. Thus, this project is expected to demonstrate the suitability of doping as a promising approach that promises efficient, stable and reproducible perovskite solar cells.
