Performance enhancement of organic perovskite solar cell with graphene oxide as electron transport layer

In this paper, effective work is conducted on performance optimization in methylammonium lead triiodide with MXene absorber layer-based solar cells incorporating Spiro-OMeTAD and GO as HTL and ETL, respectively. The influences of temperature, work function of back contact, interface defect density (ETL/absorber) and parasitic resistance on the cell output parameters have also been analyzed. The solar cell device architecture of FTO/GO/CH3NH3PbI3+ MXene/Spiro-OMeTAD/Au optimized in terms of thickness and defect density of absorber layer respectively have shown a theoretical PCE of 21.37%, FF of 74.87%, Vocof 1.2220 V and Jscof 23.3594 mA/cm2. The outcome of this article offers valuable perspectives on enhancing the effectiveness, durability, and fine-tuning of MXene-based solar cells for their use in various energy applications.
