Fabrication and Characterization of Graphene Incorporated Cu Based Perovskite in Application of Perovskite Solar Cell under Ambient Condition

Abstract

In this work, we demonstrate the synthesis and characterization of Cu-based thin film perovskites and their prospective application in photovoltaic cells and light-harvesting devices, which is lead(Pb) free and environmental friendly. We studied valuable part of graphene for stability issue in CH 3 NH 3 CuCl 3 (MACuCl 3 ) Perovskites solar cell and improved band gap 2.61 eV to 2.56 eV as well. Copper ions represented responsible of this materials for the bright green photoluminescence. For assimilating MACuCl 3 and G-MACuCl 3 based Perovskites, solar cells architectures and photovoltaic performance are argued among them. The main limitations for the solar cell efficiency were found the arrangement of insubstantial mass and high absorption coefficient of the electrons as well. As per as our knowledge, this work is demonstrated of the prospective of thin film MACuCl 3 and G-MACuCl 3 perovskite as light absorber and puts down the establishment for additional development of perovskite solar cell as alternative of lead-free materials.

Mixed Organic Halide Perovskite Energy Harvester for Solar Cells

“…In the XRD spectra it was able to identify the peaks, in which some of the peaks corresponds to the peaks of methyl ammonium copper chloride and the other is that of phenyl ethyl ammonium copper chloride. By studying the crystalline full width and half width maxima (FWHM) we can realize that smallest FWHM is in the plane (002)* at 16.09˚ [27]. Diffraction peaks at 16.09˚, 28.7301˚,37.69˚,38.55˚, 51.46˚ are indexed to be (002)*, (003)*, (221)*, (004)*, (005)* for methyl ammonium copper chloride and the rest of the peaks identified as that of phenyl ethyl ammonium copper chloride [28].…”

Characterization and Fabrication of Pb-Based Perovskites Solar Cells under Atmospheric Condition and Stability Enhancement

“…One of the most promising materials, lead halide perovskites have been demon-strated for next-generation photovoltaic and light-harvesting application [1] [2]. Organic-Inorganic lead halide perovskites have been attracted great interest from many researchers due to tremendous improvement of power conversion efficiency (PCE), 3.9% to more than 22% within short research of time 2009 to 2020 [3] [4] [5].…”
