TL;DR: In this paper, high performance polymer heterojunction solar cells fabricated from an alternating copolymer of 2,7-silafluorene (SiF) and 4,7di(2′-thienyl)-2,1,3-benzothiadiazole (DBT) (PSiF-DBT), with [6,6]-phenyl-C61-butyric acid methyl ester as the electron acceptor were investigated.

TL;DR: High performance solar cells fabricated from an easily synthesized donor-acceptor polymer show maximum power point up to 6.0 mW cm−2, with an open-circuit voltage of 0.89 V, making this polymer a particularly promising candidate for high-efficiency low-cost polymer solar cells.

TL;DR: This work demonstrates a rational design for fine-tuned crystallinity of polymer acceptors, and reveals the high potential of all-PSCs through structure and morphology engineering of semicrystalline polymer:polymer blends.

TL;DR: This work demonstrates the great potential of isoindigo moieties as electron-deficient units for building donor-acceptor-type polymers for high-performance polymer solar cells.

TL;DR: This review is an attempt to summarize the structures and properties of the isoindigo-based polymers and small molecules that have been reported in the literature since their inception in 2010 and is expected that this review will present useful guidelines for the design of efficient isoindio-based materials for applications in solar cells and FETs.
