TL;DR: In this article, the surface plasmon resonance effect of carbon-dot-supported silver nanoparticles (CD-Ag nanoparticles) was used as reducing agent and template to fabricate solution-processable polymer light-emitting diodes and polymer solar cells.

TL;DR: This work exemplifies how the functionality of metal halide perovskites is extremely sensitive to the nature of the (nano)crystalline surface and presents a route through which to control the formation and migration of surface defects to achieve bandgap stability for light emission and could also have a broader impact on other optoelectronic applications-such as photovoltaics-for which band gap stability is required.

TL;DR: B Balanced charge injection and transport are a basic requirement for highly effi cient optoelectronic devices and poor electron injection continues to be a serious problem for realizing highly effI cient PLEDs.

TL;DR: Amine-based solvent treatment between the TiO2 and the perovskite layers enhances electron injection and extraction and reduces the recombination of photogenerated charges at the interface.

TL;DR: This work reports significant beneficial effects using a new treatment based on amine-based passivating materials (APMs) to passivate the defect sites of methylammonium lead tribromide (MAPbBr3) through coordinate bonding between the nitrogen atoms and undercoordinated lead ions.
