TL;DR: In this article, a Fourier-transform photocurrent spectroscopy and electroluminescence was used to show the existence of a low but non-negligible charge transfer state as the possible origin of VOC loss.

TL;DR: A simple strategy is reported to produce filter-free narrowband OPDs with outstanding performances by manipulating exciton dissociation with a hierarchical device structure to intentionally manipulate the dissociation of Frenkel excitons.

TL;DR: In this article, a ternary blend bulk-heterojunction (BHJ) all-polymer solar cells with a high fill factor of 78% was proposed.

TL;DR: A series of new electron acceptors containing a truxene core with intense optical absorption were synthesized and used for non-fullerene organic solar cells as discussed by the authors, which led to complementary light spectra with narrow band-gap donor polymers and high open circuit voltage (Voc) in solar cells.

TL;DR: High-performance all-PPDs developed by using a narrowband-gap p- type polymer NT40 and an n-type polymer poly{[ N, N'-bis(2-octyldodecyl)-naphthalene-1,4,5,8-bis(dicarboximide)-2,6-diyl]- alt-5,5'-(2,2'bithiophene)} exhibited a high working frequency over 10 kHz
