Growth and Exploration of Inorganic Semiconductor Electron and Hole Transport Layers for Low-Cost Perovskite Solar Cells

The perovskite exhibited outstanding performance and was a promising alternative material for low-cost, high power conversion efficiency (PCE) solar cell application. To avoid the high-cost organic materials as electron transport layers (ETL) hole (HTL) in cells (PSCs), here introduce inorganic semiconductor nanomaterials ZnS CuS work an ETL HTL, respectively. In this work, we selected chalcogenides such zinc sulfide (ZnS) copper (CuS) 2-electron utilized them For proposed structure FTO/ZnS/perovskite (CH3NH3PbI3)/CuS/Ag, deposition of has been achieved via different techniques thermal evaporation, spin coating doctor blade, X-ray diffraction Field effect scanning microscopy (FESEM) with Energy-dispersive spectroscopy were used to characterize structural morphological properties prepared samples. UV-Visible spectrophotometer current density-voltage curve measure optical electrical parameters deposited layers, From J-V characteristics, fabricated PSCs, estimated PCE is about 0.28 %, open-circuit voltage (VOC) = 0.29 V, short-circuit density (JSC) 3.96 mA/cm2. results are good nanomaterial study future studies. HIGHLIGHTS study, chalcogenide sulphide layer cadmium (CdS) applications investigated Use easy simple deposit methods chemical bath blade method possibility using field cells, although obtained very small, indication response application GRAPHICAL ABSTRACT
