Optical Durability of Contemporary PV Encapsulants Through Artificial UV Weathering

Progress in Photovoltaics: Research and Applications, EarlyView.
Encapsulant choice can be used to mitigate UV‐induced degradation in modern silicon photovoltaic modules, but this strategy is only effective if encapsulants are durable under UV weathering. This study identifies optical changes to 14 commercial encapsulants as a function of UV weathering and identifies that, while changes to material transmittance ...

A novel sulfur‐containing photoinitiator based on benzophenone derivatives for rapid photopolymerization

Smart Molecules, EarlyView.
This study develops a series of unimolecular photoinitiators, BP‐S1‐5, by incorporating hydrogen‐donating groups into a benzophenone framework. This method reduces the reliance on co‐initiators, and enables BP‐S1‐5 with efficient photoinitiation and excellent molding capability.

Visible‐light‐promoted catalyst‐free benzylic C‐H oxidation using molecular oxygen as a green oxidant

Smart Molecules, EarlyView.
A green and simple photo‐oxygenation of benzylic C‐H bond with molecular oxygen was developed for the preparation of a series of carbonyl compounds. The straightforward C‐H carbonylation strategy features catalyst‐ and additive‐free reaction conditions, only oxygen as a green oxidant, broad scope and scalable, and the simple‐operation nature.
