Summary: This study investigates the influence of processing solvent on the morphology and performance of organic photovoltaic devices. The results demonstrate that chloroform processing solvent can achieve optimal power conversion efficiency by forming a fibrillar network morphology that facilitates exciton dissociation, charge transport and extraction. The addition of chloronaphthalene leads to over-crystallization and lower device efficiency. Chlorobenzene and toluene suppress crystallization, resulting in decreased short-circuit current and fill factor.

Summary: While polymer/polymer blend systems still have lower power conversion efficiencies compared to small-molecule-acceptor-based systems, the use of a ternary blending strategy holds promise in achieving a desired nanoscale blend morphology to bridge the efficiency-stability gap in all-polymer solar cells. In this study, a narrow-band-gap chlorinated polymer acceptor (PY-2Cl) was incorporated into the PM6:PY-1S1Se host blend, resulting in extended absorption spectra, improved molecular packing, solidified blend microstructure, and reduced non-radiative recombination. The resulting ternary blend achieved a PCE of 18.2% (certified value 17.8%), the highest reported for all-PSCs. Furthermore, the ternary blend demonstrated lower Urbach energy and better operational stability compared to corresponding binary systems. This work paves the way for enhancing the development of high-performance all-polymer systems through molecular design and ternary strategies.

Summary: Organic photovoltaics (OPV) is an effective method for collecting solar energy, achieving a power conversion efficiency (PCE) of over 19% when processed with halogenated solvents. Tailoring the absorption band of photoactive materials can further enhance OPV performance, and by developing a series of non-fullerene acceptors (NFAs) with varied side-group conjugations, an enhanced absorption band in the short-wavelength region (SWR) is observed. The molecular structures and geometries that improve SWR absorption are elucidated, and a clear relationship between enhanced SWR absorption and reduced singlet-triplet energy gap is established, both of which can be tailored through rational structure design of NFAs. Finally, a rationally designed NFA, BO-TTBr, achieves a decent PCE of 18.5% when processed with a non-halogenated green solvent.
