TL;DR: A new, easy, and efficient approach is reported to enhance the driving force for charge transfer, break tradeoff between open-circuit voltage and shortcircuit current, and simultaneously achieve very small energy loss, very high open-Circuit voltage, and very high efficiency in fullerene-free organic solar cells via an energy driver.

TL;DR: A fused-undecacyclic electron acceptor (IUIC) was designed, synthesized and applied in organic solar cells (OSCs) and semitransparent OSCs (ST-OSCs), which showed higher values in opencircuit voltage, short-circuit current density, and thereby much higher power conversion efficiency (PCE) than those of the ITIC4-based counterpart as discussed by the authors.

TL;DR: A unidirectional extension of a smaller fused-ring system into a larger one in a single direction will increase the conjugation length, allowing a fine tuning of electronic properties, and a bidirectionally extended AOIC has the highest mo-bility.

TL;DR: A series of fused-ring electron acceptors (FREAs) based on naphthalene-fused octacyclic cores end-capped by 3-(1,1-dicyanomethylene)-5,6-difluoro-1- indanone (NOICs) using a bottom-up approach to improve power conversion efficiencies and performance of organic solar cells.

TL;DR: In this article , a series of fullerene dyads FP-Cn (n = 4, 8, 12) were designed to replace PCBM as an electron transport layer, where [60]fullerene is linked with a terpyridine chelating group via a flexible alkyl chain of different lengths as a spacer.
