Abstract

Titanium dioxide (TiO2) possess superior electrical characteristics which is used for perovskite solar cells, that acts as an electron transport layer (ETL). However, TiO2 needs high temperature annealing for crystallization. The purpose of this study is to examine the problems regarding TiO2 as an ETL material in perovskite solar cells and to suggest potential methods to address these concerns. Using TiO2 as an ETL material, the research will comprise a thorough literature analysis of the state-of-the art in perovskite solar cells with an emphasis on the problems of morphological control, defect development, bandgap restrictions, and environmental considerations. Additionally, experimental work will be done to create and characterize TiO2-based ETLs for perovskite solar cells as part of the project. The management of the synthesis conditions and deposition techniques will optimize the shape of the TiO2 layer. The structural, electrical, and optical characteristics of the TiO2 layer will be examined utilizing a variety of characterization techniques to assess its quality. The study will suggest possible ways to get over the problems of using TiO2 as an ETL material in perovskite solar cells.
