Published: June 27, 2024

Abstract Inverted perovskite solar cells (PSCs) have attracted considerable attention due to their distinct advantages, including minimal hysteresis, cost‐effectiveness, and suitability for tandem applications. Nevertheless, the solution processing low formation energy of perovskites inevitably lead numerous defects formed at both bulk interfaces layer. These can act as non‐radiative recombination centers, significantly impeding carrier transport posing a substantial obstacle stability further enhancing power conversion efficiency (PCE). This review delves into detailed discussion nature origin characterization techniques employed defect identification. Furthermore, it systematically summarizes methods detection approaches passivating interface within film in inverted PSCs. Finally, this offers perspective on employing upscaling passivation engineering modules. It is hoped provides insights PSCs

Inorganics, Journal Year: 2024, Volume and Issue: 12(4), P. 123 - 123

Published: April 21, 2024

In this study, a novel systematic analysis was conducted to explore the impact of various parameters, including acceptor density (NA), individual layer thickness, defect density, interface and metal electrode work function, on efficiency within FTO/ZnO/CsSnI3/NiOx/Au perovskite solar cell structure through SCAPS-1D (Solar Cell Capacitance Simulator in 1 Dimension) simulation. ZnO served as electron transport (ETL), CsSnI3 absorption (PAL), NiOx hole (HTL), all contributing optimization device performance. To achieve optimal power conversion (PCE), we determined ideal PAL (NA) be 2 × 1019 cm−3 thicknesses 20 nm for ETL (ZnO), 700 (CsSnI3), 10 HTL (NiOx), with remaining Au. As result process, increased from 11.89% 23.84%. These results are expected contribute performance enhancement eco-friendly, lead-free inorganic hybrid cells Sn-based PAL.
