Using CuO/ZnO as Two-Dimensional Hole/Electron Transport Nanolayers in Unleaded FASnI Perovskite Solar Cells.

A Pb-free FASnI perovskite solar cell improved by using CuO/ZnO as two-dimensional-based hole/electron transport nanolayers has been proposed and studied by using a SCAPS-1D solar simulator. To calibrate our study, at first, an FTO/ZnO/MAPbI/CuO/Au multilayer device was simulated, and the numerical results (including a conversion efficiency of 6.06%, an open circuit potential of 0.

Effects of electron transport layer type on the performance of Pb-free CsAgBiBr double perovskites: a SCAPS-1D solar simulator-based study.

Recently, due to the superior stability and lower risk of toxicity, the development of Pb-free halide double perovskite materials has revived excellent interest. In this work, Pb-free perovskite solar cells (PSCs) with ITO/ETL/CsAgBiBr/CuO/Au multilayer structures with CsAgBiBr double perovskite as the solar light absorber layer, some electron transport layers (ETLs) and CuO as a hole transport layer have been introduced. Then, the effects of various thicknesses of the absorber layer and also ETL materials, like ZnO, C, CdS, SnO, phenyl-C-butyric acid methyl ester (PCBM), and TiO, on the device performance (including photoelectronic conversion efficiency (PCE), fill factor (FF%), short circuit current density (Jsc), and open-circuit voltage (V)) were examined with the help of a solar cell simulator (SCAPS-1D).

Lead-free MAGeI as a suitable alternative for MAPbI in nanostructured perovskite solar cells: a simulation study.

The lead is a heavy metal with hazardous impacts on environment and human life. Lead-free perovskite solar cells have attracted much attention in recent years, due to eco-friendly characteristics. Meanwhile, Pb-containing cells showed the highest efficiencies among the various types of cells.
