Abstract

Defect passivation is increasingly becoming a viable method of performance optimization in organic–inorganic methylammonium lead iodide perovskite-based solar cells. In this research, synthesized manganese dioxide (MnO₂) material via chemical method was used to sensitize all-solid-state halide perovskite solar cells (PSCs). Additionally, titanium dioxide (TiO₂) and reduced graphene oxide synthesized through Sol gel and Hummers’ methods, respectively were incorporated as electron transporting layer, and MnO₂ was used to enhance graphite counter electrode. ITO/rGO/TiO₂/CH₃NH₃PbI₃/Gr and ITO/rGO/TiO₂/CH₃NH₃PbI₃/Gr-MnO₂ planar PSCs were fabricated via spin coating technique, and exposed to solar illuminator in order to evaluate their photovoltaic performance. ITO/rGO/TiO₂/CH₃NH₃PbI₃/Gr-MnO₂ film showed a power conversion efficiency of 11.34% compared to 8.22%, for ITO/rGO/TiO₂/CH₃NH₃PbI₃/Gr film. The percentage enhancement value of 27.50% was realized with MnO₂ passivation. This research demonstrates that wide bandgap two-dimensional materials can tune the functionality of PSCs and afford a lead on designing of advanced passivation media to further tailor halide perovskite properties via grain boundary functionalization.

期刊介绍： The Journal of Materials Science: Materials in Electronics is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics, covering the ground between fundamental science, such as semiconductor physics, and work concerned specifically with applications. It explores the growth and preparation of new materials, as well as their processing, fabrication, bonding and encapsulation, together with the reliability, failure analysis, quality assurance and characterization related to the whole range of applications in electronics. The Journal presents papers in newly developing fields such as low dimensional structures and devices, optoelectronics including III-V compounds, glasses and linear/non-linear crystal materials and lasers, high Tc superconductors, conducting polymers, thick film materials and new contact technologies, as well as the established electronics device and circuit materials.
