Thermally Fine-Tuned NiOx&ndash;MAPbI3 Interfaces Enabled by a Polymeric Surface Additive for High-Sensitivity Self-Powered Photodetectors

Published on 2026-01-30 by HyeRyun Jeong, Kimin Lee, Wonsun Kim, Byoungchoo Park @MDPI

Abstract: Self-powered perovskite photodiodes provide an attractive platform for low-power and high-sensitivity photodetection; however, their performance capabilities are often constrained by inefficient interfacial charge extraction and noise suppression. Here, we report a polymer-mediated interfacial engineering strategy for methylammonium lead iodide (MAPbI3) photodiodes by integrating thermally optimized nickel oxide (NiOx) hole-transport layers (HTLs) with a nonionic polymeric surfactant, poly(oxyet[...]


Our summary: A polymer-mediated interfacial engineering strategy enhances the performance of self-powered perovskite photodiodes.

Abstract: Chemical looping combustion (CLC) has been recognized as a promising CO2 capture technology, in which oxygen carriers (OCs) transport lattice oxygen to the fuel instead of the air. This study aims to evaluate a newly developed perovskite OC for biomass CLC and to clarify the role of staged fuel conversion in improving gas&amp;ndash;solid redox efficiency. This is the first application of perovskite OC CaMn0.625Ti0.125Fe0.125Mg0.125O3 in biomass CLC using a dual-stage fluidized bed. The perov[...]
