Ternary blend organic solar cells (TB-OSCs) incorporating multiple donor and/or acceptor materials into the active layer have emerged as a promising strategy to simultaneously improve overall device parameters for realizing higher performances than binary devices. Whereas introducing also results in more complicated morphology their counterparts. Understanding is crucially important further improving performance of TB-OSC. This review introduces solubility and miscibility that affect ternary blends. Then, this summarizes recent processes study on blends from aspects molecular crystallinity, packing orientation, domain size purity, directly observation morphology, vertical phase separation well morphological stability. Finally, summary prospects TB-OSCs are concluded.

Here, we combine two donor polymers with a relatively short synthesis method and fabricate ternary organic solar cells (OSCs) high efficiency decent figure-of-merit. A series of characterizations show that the optimal morphology blend is result coupling competition PTQ10 PTVT-T, where molecular packing phase separation motif broken but strong aggregation PTVT-T suppressed, resulting in efficient charge transport collection, as well suppressed bimolecular recombination. Moreover, previously reported solvent-vapor-assisted casting method, taken an understanding-guided optimization, pushes system's to 19.11%. Furthermore, PTVT-T-containing systems clearly better light soaking thermal stability than binary control system, benefiting from durable polymer matrix. Our work provides useful approach for developing efficient, stable, low-cost OSCs based on state-of-the-art donor/acceptor through design.

All-polymer solar cells (All-PSCs) are considered the most promising candidate in achieving both efficient and stable organic photovoltaic devices, yet field has rarely presented an in-depth understanding of corresponding device stability while efficiency is continuously boosted via innovation polymer acceptors. Herein, a ternary matrix built for all-PSCs with optimized morphology, improved film ductility importantly, better operational than its parental binary counterparts, as platform to study underlying mechanism. The target system PQM-Cl:PTQ10:PY-IT (0.8:0.2:1.2) exhibits alleviated burn-in loss morphology under light soaking, which supports promoted lifetime. comprehensive characterizations fresh light-soaked active layers lead clear illustration opposite morphological physical degradation direction PQM-Cl PTQ10, thus resulting delicate balance at optimal system. Specifically, enlarging tendency shrinking preference PTQ10 terms phase separation leads their mixing phase; hole transfer kinetics PQM-Cl:PY-IT host stabilized by incorporating PTQ10. This work succeeds reaching deep insight into all-PSC's promotion rational design, booms prospect gaining high-performance all-PSCs.

Abstract Layer‐by‐layer all‐polymer solar cells (LbL all‐PSCs) are prepared with PM6 and PY‐IT by using sequential spin coating method. The exciton dissociation efficiency in acceptor layer near electrode is rather low due to the limited diffuse distance impossible energy transfer from narrow bandgap wide donor. In this study, less incorporated into enhance electrode. A power conversion (PCE) of 17.45% achieved LbL all‐PSCs incorporating 10 wt% layer, which much larger than 16.04% PCE PM6/PY‐IT‐based all‐PSCs. Over 8% enhancement can be realized attributed enhanced utilization layers confirmed quenched photoluminescence (PL) emission PY‐IT:PM6 films. Meanwhile, charge transport optimized PM6, as molecular arrangement. This study indicates that strategy donor has great potential fabricating efficient improving
