Multifunctional ionic liquid boosts the efficiency of hole transport layer‐free carbon‐based perovskite solar cells beyond 20%

FlexMat, EarlyView.
HTL‐free carbon‐based PSCs are promising in stability but limited by efficiency. Systematic screening identifies DMAFo as an optimized ionic‐liquid additive: the DMA+ regulates lattice distortion and relieves residual stress, while Fo‒ passivates halide vacancies, and ameliorates band‐alignment.

Low‐threshold FAPbBr3 lasers based on a dual‐additive strategy

FlexMat, EarlyView.
This study developes a dual‐additive strategy to fabricate high‐quality FAPbBr3 perovskite films, exhibiting a low surface RMS roughness of 1.36 nm and a high photoluminescence quantum efficiency of 63.6%. Based on the superior film, lasing with a record‐low threshold of 15.5 μJ/cm2 for FAPbBr3 under nanosecond‐pulsed pumping at room temperature are ...
