Molecular ordering effect of semi-paracrystalline polymers on the solution aggregation structure, morphology, and performance polymer/nonfullerene blends has been thoroughly investigated by advanced neutron scattering complementary techniques.
Achieving environmentally friendly solvent-processed high-performance organic photovoltaic cells (OPVs) is a crucial step toward their commercialization. Currently, OPVs with competitive efficiencies rely heavily on harmful halogenated solvent additives. Herein, the green and low-cost 9-fluorenone (9-FL) employed as solid additive. By using o-xylene/9-FL system, PM6:BTP-eC9-based devices deliver power-conversion of 18.6% 17.9% via spin-coating blade-coating respectively, outperforming all...
Abstract Stretchable electrodes are critical to the development of advanced technologies such as human–machine interaction, flexible sensing, and wearable power supply, making them significant research value. However, current preparation methods for high‐performance stretchable complex inefficient, posing challenges their large‐scale application in realm wearables. To address this need, a straightforward efficient embedding strategy is reported fabricating silver nanowire/thermoplastic...

Compared to broadly used...
Abstract Current state‐of‐the‐art organic photovoltaic (OPV) films, composed of conjugated polymer donors and small molecule acceptors, are often limited by the high brittleness their rigid backbones, which restricts application in wearable devices. In contrast, all‐polymer OPVs have demonstrated enhanced intrinsic stretchability, but further advancements necessary to meet demands. Here, an uncharted strategy is reported enhance mechanical stretchability performance incorporating a...
A comprehensive and critical review of state the art hybrid quantum dots organic solar cells is presented with goal advancing their commercial applications.
The past decade has witnessed the prosperity of organic photovoltaic cells (OPVs). In addition to efficiency and cost, stability is another challenge that OPVs face in their practical application. Continuous thermal stress often accelerates crystallization phase separation active layers, leading a decreased performance. Developing simple effective strategies prolong lifetime under heating attracted increasing attention. this work, an unexplored random copolymer named PY was incorporated as...
The strong aggregation of Poly(3-hexylthiophene) (P3HT) severely limits its use as the hole-transport material in emerging quantum dot photodetectors and photovoltaics. Herein, we propose a facile cost-effective strategy to control solution-state hole transporting layers by designing dual polythiophene blend based on P3HT alkylthio-substituted analogue named Poly(3-hexylthiothiophene) (P3HTT). In our photodetector device, have used transport layer achieved specific detectivity (D*) order...
Owing to the advantages of low synthetic cost and high scalability synthesis, polythiophene its derivatives (PTs) have been interest in community organic photovoltaics (OPVs). Nevertheless, typical efficiency PT based photovoltaic devices reported so far is much lower than those prevailing push-pull type conjugated polymer donors. Recent studies underscored that excessively miscibility between nonfullerene acceptor major reason accounting for unfavorable active layer morphology inferior...
