High-efficiency all-polymer solar cells with less thickness-dependent behavior are demonstrated by using a low bandgap n-type conjugated polymer N2200 as acceptor and an absorption-complementary difluorobenzotriazole-based medium-bandgap J51 donor. As service to our authors readers, this journal provides supporting information supplied the authors. Such materials peer reviewed may be re-organized for online delivery, but not copy-edited or typeset. Technical support issues arising from...
The ternary strategy has been widely identified as an effective approach to obtain high-efficiency organic solar cells (OSCs). However, for most OSCs, the nonradiative voltage loss lies between those of two binary devices, which limits further efficiency improvements. Herein, asymmetric guest acceptor BTP-2F2Cl is designed and incorporated into a PM1:L8-BO host blend. Compared with L8-BO neat film, L8-BO:BTP-2F2Cl blend film shows higher photoluminescence quantum yield larger exciton...
A novel electron acceptor, BTP-H2, demonstrates a high efficiency of 18.5% with V oc 0.932 V. It also enables the ternary device to yield an 19.2%, ranking highest among single-junction organic photovoltaics.
Conjugated side-chain-isolated D–A copolymers, based on the donor unit of benzodithiophene (BDT) with a thiophene-conjugated side chain, thiophene π bridge, and acceptor benzotriazole (BTA) or without fluorine substitution (PBDT-FBTA PBDT-HBTA), were designed synthesized for elucidating their structure–property relationships. The copolymer films demonstrated well-defined absorption peaks steep edges, consistent rigid ordered structures in solid films. chain BDT copolymers aroused 15-nm...
A ternary structure has been demonstrated as being an effective strategy to realize high power conversion efficiency (PCE) in organic solar cells (OSCs); however, general materials selection rules still remain incompletely understood. In this work, two nonfullerene small-molecule acceptors 3TP3T-4F and 3TP3T-IC are synthesized incorporated a third component PM6:Y6 binary blends. The photovoltaic behaviors the resultant OSCs differ significantly, despite comparable energy levels. It is found...
We tackle the human motion imitation, appearance transfer, and novel view synthesis within a unified framework, which means that model once being trained can be used to handle all these tasks. The existing task-specific methods mainly use 2D keypoints (pose) estimate body structure. However, they only expresses position information with no abilities characterize personalized shape of individual person limbs rotations. In this paper, we propose 3D mesh recovery module disentangle pose shape,...

While compromise between charge generation and recombination remains a challenge. Here, mixed diluent for further improving efficiency OPV proposed. Specifically, high-performance system with polymer donor, i.e., PM6, nonfullerene acceptor (NFA), BTP-eC9, diluted by diluents, which involve high bandgap NFA BTP-S17 low BTP-S16 (similar that...

Supported by statistical analyses device degradation data, morphological characteristics...
Perovskite hybrid solar cells (pero-HSCs) were demonstrated to be among the most promising candidates within emerging photovoltaic materials with respect their power conversion efficiency (PCE) and inexpensive fabrication. Further PCE enhancement mainly relies on minimizing interface losses via engineering quality of perovskite film. Here, we demonstrate that PCEs pero-HSCs are significantly increased 14.0% by incorporation a solution-processed perylene–diimide (PDINO) as cathode layer...
Herein, a simple "Same-A-Strategy" (SAS), constructing p-type and n-type photovoltaic materials with the same electron-accepting (A) unit of benzotriazole, is adopted to initially control energy offsets. Then, chlorine atoms are introduced into conjugated side chain benzo[1,2-b:4,5-b′]dithiophene (BDT) donor polymer fine-tune optoelectronic properties. The chlorinated J52-Cl, blended non-fullerene small molecule acceptor BTA3, yields very offsets (ΔEHOMO = 0.10 eV, ΔELUMO 0.28 eV) decreased...

Abstract Polymerization sites of small molecule acceptors (SMAs) play vital roles in determining device performance all‐polymer solar cells (all‐PSCs). Different from our recent work about fluoro‐ and bromo‐ co‐modified end group IC‐FBr (a mixture IC‐FBr1 IC‐FBr2), this paper, we synthesized purified two regiospecific substituted groups (IC‐FBr‐ o & IC‐FBr‐ m ), which were then employed to construct regio‐regular polymer named PYF‐T‐ , respectively . In comparison with its isomeric...
