Abstract The power conversion efficiencies (PCEs) of single‐junction organic solar cells (OSCs) have surpassed 19%, owing to the emerging Y‐series nonfullerene acceptors (NFAs). Undoubtedly, and flexibility chemical design has been a strong driver for this rapid efficiency improvement in OSC field. Over course past 3 years, variety modifications made structure Y6 acceptor, large number NFAs reported further improve performance. Herein, we present our insights into rationale behind acceptor...
Two new glycolated semiconducting polymers PgBT(F)2gT and PgBT(F)2gTT of differing backbone curvatures were designed synthesised for application as p-type accumulation mode organic electrochemical transistor (OECT) materials.

Small band gap molecular semiconductors are of interest for the development transparent electronics. Here we report two near-infrared (NIR), n-type small molecule semiconductors, based upon an acceptor–donor–acceptor (A-D-A) approach.

Both materials were synthesized by a one-pot, 6-fold nucleophilic displacement...

Salt rock is internationally recognized as an excellent medium for energy storage. However, most of the domestic salt mines are lacustrine laminated formations with mudstone interlayers, which have different creep characteristics to pure rocks. Therefore, in this paper, uniaxial compression tests were carried out on a interlayer Huai’an, Jiangsu, China, and multistage mechanical behavior was investigated using acoustic emission (AE) technology.
