Stability of Organic Photovoltaics: From Root Causes to Advanced Analytical Techniques
Advanced Energy Materials, EarlyView.This review explains the causes and mechanisms of degradation in organic photovoltaics (OPVs). It explores how various factors, including heat, light, oxygen, and inherent material properties, influence OPV stability. The study categorizes degradation pathways and analyzes their impact on device performance, providing insights into the fundamental ...

Angewandte Chemie, EarlyView.Stability is the key challenge for Sn─Pb perovskites. This work tackles the critical stability issue by introducing phenol hydroxylation in the hole transporting material (HTM). The phenol group enhances oxidation resistance and regulates crystallization kinetics, while fluorine improves energy alignment.

Advanced Energy and Sustainability Research, EarlyView.Two crosslinkable molecules are introduced into the buried interface of perovskite to regulate the interfacial contact between [2‐(3,6‐dimethoxy‐9H‐carbazol‐9‐yl)ethyl]phosphonic acid and perovskite. The cross‐linked interfacial layer can control the crystallization process of the perovskite thin film and adjust the energy level alignment.

Angewandte Chemie, EarlyView.The introduction of both PMAI and 2PACz into the precursor effectively cleaves edge‐shared Pb‐I octahedra to facilitate the transformation from PbI2 to PbI3− complexes as prenucleation clusters, and thus produces much larger colloidal particles with accelerated nucleation. Simultaneously, the crystallization in both spin‐coating and annealing processes

Angewandte Chemie, EarlyView.In a solution of two metastable photoacids with contrasting absorption maxima, the solution pH may be control by varying the wavelength of the visible light input. This pH change governs the interaction between the Zn2+ cation and two competing anionic chiral ligands, detected by a change in circular dichroism (CD) spectra.
