TL;DR: The effectiveness of the n‐doping strategy highlights electron transport in NFA‐based OPVs as being a key issue and results in balanced hole and electron mobilities, higher absorption coefficients and increased charge‐carrier density within the BHJ, while significantly extending the cells' shelf‐lifetime.

TL;DR: A new narrow-bandgap polymer acceptor L14 is synthesized by copolymerizing a dibrominated fused-ring electron acceptor (FREA) with distannylated bithiophene imide, which not only shows a narrow bandgap and high absorption coefficient, but also low-lying frontier molecular orbital (FMO) levels.

TL;DR: Interestingly, thermal annealing does not alter film crystallinity, nor R-SoXS characteristic size scale, relative average phase purity, nor TEM-imaged phase separation, but rather facilitates Y6 migration to the BHJ film top surface, changes the PBDB-TF/Y6 vertical phase separa-tion and intermixing, and reduces bottom surface roughness.
