The power conversion efficiencies of polymer solar cells were largely improved by introducing a non-conjugated small-molecule electrolyte as a cathode interlayer.

Three luminogens were designed and synthesied by integrating TPE with hole-transporting carbazole (Cz) and/or electron-transporting 1,2-diphenyl-1H-benzimidazole (PBi), and the bare tetraphenylethene and another donor−acceptor (D−A) compound of aggregation-caused quenching (ACQ)...

An improved concentration of phosphorescent dopant for highly-efficient hybrid white organic light-emitting diodes based on a high radiative exciton ratio (80%) deep-blue emitter has been developed.
