TL;DR: In this paper, a ladder-type electron-deficient core-based central fused ring (Dithienothiophen[3.2-b]- pyrrolobenzothiadiazole) with a benzothiadiadiazoles (BT) core was proposed to fine-tune its absorption and electron affinity.

TL;DR: The effects of the fluorine atom number and position on electronic properties, charge transport, film morphology, and photovoltaic properties are investigated.

TL;DR: In this article, an alloy-like composite is formed between Y6 and a newly designed derivative, BTP-M. Employing an electron-pushing methyl substituent as a replacement for the electron-withdrawing F atoms on Y6, the obtained Y6:BTP-m alloy can simultaneously optimize energy levels to reduce energy loss as well as the morphologies of the active layers to favor photocurrent generation, leading to an enhanced open-circuit voltage (Voc) of 0.875 V together with a larger shortcircuit current density (Jsc

TL;DR: A fused hexacyclic electron acceptor, IHIC, based on strong electron-donating group dithienocyclopentathieno[3,2-b]thiophene flanked byStrong electron-withdrawing group 1,1-dicyanomethylene-3-indanone, is designed, synthesized, and applied in semitransparent organic solar cells (ST-OSCs).

TL;DR: In this article, a non-fullerene electron acceptor, called SF(DPPB)4, was designed and synthesized for poly(3-hexyl thiophene) (P3HT) donor in polymer solar cells (PSCs).
