چکیده
In this study, we analyzed the maximum power conversion efficiency (PCE) of a photovoltaic cell with an ITO/ZnO/CsPbIxBr3?x/NiOx/Au structure, using ZnO and NiOx as inorganic charge transport layers CsPbIxBr3?x absorption layer. We optimized thickness each layer investigated effects defect density interface density. To achieve highest PCE, optimal thicknesses were 300 nm for electron (ZnO), 60 hole (NiOx), 1000 The absorber was maintained at approximately 1015 cm?3, 1011 cm?3. PCE obtained through optimization these factors 23.07%. These results are expected to contribute performance perovskite solar cells that use carrier layers.

Optimization of an Electron Transport Layer to Enhance the Power Conversion Efficiency of Flexible Inverted Organic Solar Cells
The photovoltaic (PV) performance of flexible inverted organic solar cells (IOSCs) with an active layer consisting of a blend of poly(3-hexylthiophene) and [6, 6]-phenyl C(61)-butlyric acid methyl ester was investigated by varying the thicknesses of ZnO seed layers and introducing ZnO nanorods (NRs). A ZnO seed layer or ZnO NRs grown on the seed layer were used as an electron transport layer an...
