Understanding the molecular structure and self-assembly of thiadiazole-derived non-fullerene acceptors (NFAs) is very critical for elucidating origin their extraordinary charge generation transport properties that enable high power conversion efficiencies to be achieved in these systems. A comprehensive crystallographic study on a state-of-the-art NFA, Y6, its selenium analog, CH1007, has been conducted which revealed face-to-face π-core interaction induced by benzo[2,1,3]thiadiazole S-N-containing moieties plays significant role governing geometries unique packing Y6 CH1007 ensure superior charge-transport properties. Moreover, benefitting from red-shifted optical absorption via substitution, photovoltaic devices based PM6:CH1007:PC71BM ternary blend delivered an exceptionally short-circuit current 27.48 mA/cm2 efficiency 17.08%.

Molecular doping has recently been shown to improve the operating characteristics of organic photovoltaics (OPVs). Here, we prepare neutral Diquat (DQ) and use it as n-dopant performance state-of-the-art OPVs. Adding DQ in ternary bulk-heterojunction (BHJ) cells based PM6:Y6:PC71BM is found consistently increase their power conversion efficiency (PCE) from 16.7 17.4%. Analyses materials devices reveal that acts n-type dopant morphology modifier for BHJ leading observable changes its surface topography. The resulting n-doped BHJs exhibit higher optical absorption coefficients, balanced ambipolar transport, longer carrier lifetimes suppressed bimolecular recombination, which are ultimately responsible increased PCE. was successfully extended OPVs on PM6:BTP-eC9:PC71BM a maximum PCE 18.3% (uncertified) achieved. Our study highlights promising application next generation solar cells.

The ternary blend is demonstrated as an effective strategy to promote the device performance of organic photovoltaics (OPVs) due dilution effect. 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 BTP-eC9). better miscibility BTP-eC9 can dramatically enhance open-circuit voltage (VOC ), while maximizes or short-circuit current density (JSC ). interplay BTP-17 enables recombination, thus leading 19.76% (certified 19.41%), best among single-junction OPVs. Further analysis on carrier dynamics validates efficacy diluents balancing be attributed more diverse energetic landscapes improved morphology. Therefore, this work provides commercialization.
