Summary: Organic photovoltaics (OPVs) have undergone three stages of development, including optimizing bulk heterojunctions, improving donor-acceptor match, and developing non-fullerene acceptors (NFAs). NFAs have resulted in higher power conversion efficiencies (PCEs) surpassing 15% due to reduced energy losses and increased quantum efficiencies. The review provides an update on recent progress in OPV technology, including novel NFAs and donors, understanding structure-property relationships, and commercialization challenges.

Summary: This study introduces a highly emissive molecule with enhanced quenching resistance by segregating the planar MR-TADF skeleton using two bulky carbazolyl units, which significantly improves the performance of corresponding devices with a maximum external quantum efficiency of 40.0% and a full width at half maximum of 25 nm.
The steric effect of the bulky carbazolyl units largely removes the formation of detrimental excimers/aggregates, leading to an OLED example that can achieve narrow bandwidth and high EL efficiency surpassing 40% to date.
