Perovskite Cells Based on Carbon Quantum Dots: Structure, Optimization

Abstract

Perovskite ( ) photo voltaic cells (PSCs) based totally on blended perovskite minerals have attracted lots interest on the grounds that their inception. Due to its giant absorption coefficient, low cost, and convenient preparation, many researchers have conducted enormous lookup on it and explored whether or not exceptional buildings and supplies can enhance the performance of PSCs. Through the continuous efforts of researchers, the effectivity of PSCs has expanded from 3.8% when it was first born in 2009 to 25.5% now.Perovskite cells do, however, also have a number of flaws and room for development, including ility, insufficient photovoltaic performance, and perovskite skinny film crystal defects.Researchers have additionally tried many methods to enhance them, and one of the more tremendous techniques is to use carbon quantum dots (CQDs) as correction layers to enhance their performance. In this paper, the performance enhancement of CQDs on perovskite cells will be comprehensively confirmed from factors such as electron transport layer (ETL), perovskite thin films and hole transport layer (HTL) and the future PSCs will be prospected based on the modern-day results.
