TL;DR: The composites exhibited photocatalytic activity to decompose rhodamine 6G efficiently under low-power ultraviolet (UV) light, which makes the composite a perfect candidate in applications of catalysis and other areas.

TL;DR: A formamidinium(FA)-based perovskite showns superior optoelectronic properties including better stability than methylammonium-based counterparts, and Interestingly, the LED clearly shows a sub-bandgap emission at 1.7 V (bandgap 2.3 eV).

TL;DR: In this article, a dimensionally graded perovskite formation approach was proposed to reduce the photovoltage loss through the simultaneous passivation of internal bulk defects and dimensional graded two-dimensional pervskite interface defects.

TL;DR: The present work incorporates chemically modified graphene into nanocrystal SnO2 as the electron transporting layer (ETL) for highly efficient planar perovskite solar cells with power conversion efficiency of 20.2% and improved fill factor of 82%, which could be mainly attributed to the augmented charge extraction and transport.

TL;DR: In this paper, the photoactive layer of small-molecule organic semiconductor tetracene∕C60 heterojunction was used for solar cells and the external power conversion efficiency of the devices under AM 1.5 solar illumination at 100mW∕cm2 (1 sun) is 2.3±0.5% with relatively high open-circuit voltage (Voc=0.58± 0.06V).
