A Review of Preparation Techniques of Charge Transport Layer for Organic and Inorganic Perovskite Solar Cells

Abstract

The energy industry is currently very interested in designing and developing next-generation photovoltaic systems using organic-inorganic perovskite hybrid solar cells. They represent the most promising materials for high Power Conversion Efficiency (PCE), low-cost solar cells. They can also come up with answers to the global dilemma and the current energy requirements of civilization. Over the past few years, the power conversion efficiency of perovskite solar cells (PSCs) has rapidly increased, going from 3.8 to 24.2 %. The review, however, focuses on the most recent developments in the electron transport layer as perovskite solar cells are the most important element for enhancing the performance and stability of the device. These summaries include designs, electron transport (ETL) layers and perovskite active layers for efficient perovskite solar cells. The performance and stability issues with organic-inorganic halide perovskite solar cells are also covered in this article. Finally, recommendations for additional research on the ETL and perovskite active layer were offered.
