Single Step and Solution Process Fabrication of Mesoporous ZnOS Thin Film as an Effective Electron Transport Layer for the Cs‐Based Halide Double PSCs

open access: yesEnergy Science &Engineering, EarlyView.
Mesoporous ZnOS thin films were fabricated by facile spin coating as an electron transport layer (ETL) for HDP solar cells, with undoped ZnO films analyzed for comparison. The best performance, achieving a power conversion efficiency of 16.21% in the FTO/ZnOS/Cs2AgBi0.75Sb0.25Br6/CuxO/Au configuration, was obtained with single‐coated ZnOS films.

Design and Simulation of an Autotransformer‐Based 18‐Pulse AC‐DC Converter for Enhanced Power Quality in Vector‐Controlled Asynchronous Motor Drives

open access: yesEnergy Science &Engineering, EarlyView.
18‐pulse AC/DC converter with T‐connected autotransformer for feeding VCAMD. ABSTRACT Reducing harmonics in alternating current (AC) input and ripples in direct current (DC) output enhances power quality, achievable through multi‐pulse converters (MPCs). This study presents the design, simulation, and analysis (in MATLAB/Simulink) of an autotransformer‐
