While great progress has been achieved in all-polymer solar cells (all-PSCs), the efficiency of all-PSCs is primarily limited by polymer acceptors that lack a high extinction coefficient, electron mobility, and good compatibility with donors. Here we designed developed acceptor PFA1 based on non-fullerene framework fluorine substituent 1,1-dicyanomethylene-3-indanone unit. In combination an electron-donating polymer, PTzBI-oF, blend film presents extended intensified absorption profile, enhanced favorable morphology. The optimized exhibit remarkably 15.11%, which is, to best our knowledge, highest performance yet reported for all-PSC. Of particular importance applicability as universal range donors achieve impressively efficiencies. These properties enable new molecular design strategy construction toward applications high-performance all-PSCs.

Organic photovoltaics (OPVs) have progressed steadily through three stages of photoactive materials development: (i) use poly(3-hexylthiophene) and fullerene-based acceptors (FAs) for optimizing bulk heterojunctions; (ii) development new donors to better match with FAs; (iii) non-fullerene (NFAs). The application NFAs an A–D–A configuration (where A = acceptor D donor) has enabled devices efficient charge generation small energy losses (Eloss < 0.6 eV), resulting in substantially higher power conversion efficiencies (PCEs) than FA-based devices. discovery Y6-type (Y6 2,2′-((2Z,2′Z)-((12,13-bis(2-ethylhexyl)-3,9-diundecyl-12,13-dihydro-[1,2,5]-thiadiazolo[3,4-e]-thieno[2″,3″:4′,5′]thieno-[2′,3′:4,5]pyrrolo-[3,2-g]thieno-[2′,3′:4,5]thieno-[3,2-b]indole-2,10-diyl)bis(methanylylidene))bis(5,6-difluoro-3-oxo-2,3-dihydro-1H-indene-2,1-diylidene))dimalononitrile) A–DA′ D–A further propelled the PCEs go beyond 15% due smaller Eloss values (∼0.5 eV) external quantum efficiencies.

All-polymer solar cells (all-PSCs) consisting of polymer donors (PDs) and acceptors (PAs) have drawn tremendous research interest in recent years. It is due to not only their tunable optical, electrochemical, structural properties, but also many superior features that are readily available conventional polymer-fullerene (fullerene-PSCs) including long-term stability, synthetic accessibility, excellent film-forming properties suitable for large-scale manufacturing. Recent breakthroughs material design device engineering driven the power conversion efficiencies (PCEs) all-PSCs exceeding 11%, which comparable performance fullerene-PSCs. Furthermore, outstanding mechanical durability stretchability been reported all-PSCs, make them stand out from other small molecule-based PSCs as a promising supplier wearable electronic devices. This review provides comprehensive overview important work pertinent examples deliberately chosen. First, we describe key components enabled progresses rational rules efficient PDs PAs, blend morphology control, light harvesting engineering. We on understanding stability under various external conditions, highlights importance future implementation commercialization. Finally, because yet achieved full potential still undergoing rapid development, offer our views current challenges prospects.

Abstract All‐polymer solar cells (all‐PSCs) have drawn tremendous research interest in recent years, due to their inherent advantages of good film formation, stable morphology, and mechanical flexibility. The most representative widely used n ‐CP acceptor was the naphthalene diimide based D‐A copolymer N2200 before 2017, power conversion efficiency (PCE) all‐PSCs on reached over 8% 2016. However, low absorption coefficient near‐infrared (NIR) region limits further increase its PCE. In we proposed a strategy polymerizing small‐molecule acceptors (SMAs) construct new‐generation polymer acceptors. polymerized SMAs (PSMAs) possess band gap strong NIR region, which attracted great attention drove PCE 15% recently. this Minireview explain design strategies molecular structure PSMAs describe progress. Finally, current challenges future prospects are analyzed discussed.

Abstract Combining traditional textiles with triboelectric nanogenerators (TENGs) gives birth to self-powered electronic (e-textiles). However, there are two bottlenecks in their widespread application, low power output and poor sensing capability. Herein, by means of the three-dimensional five-directional braided (3DB) structure, a TENG-based e-textile features high flexibility, shape adaptability, structural integrity, cyclic washability, superior mechanical stability, is designed for sensing. Due spatial frame-column structure formed between outer yarn inner axial yarn, 3DB-TENG also endowed compression resilience, enhanced output, improved pressure sensitivity, vibrational energy harvesting ability, which can miniature wearable electronics respond tiny weight variations. Furthermore, an intelligent shoe identity recognition carpet demonstrated verify its performance. This study hopes provide new design concept high-performance textile-based TENGs expand application scope human-machine interfacing.

Despite the significant progresses made in all-polymer solar cells (all-PSCs) recently, relatively low short-circuit current density (Jsc) and large energy loss are still quite difficult to overcome for further development. To address these challenges, we developed a new class of narrow-bandgap polymer acceptors incorporating benzotriazole (BTz)-core fused-ring segment, named PZT series. Compared commonly used benzothiadiazole (BT)-containing PYT, less electron-deficient BTz renders derivatives with significantly red-shifted optical absorption up-shifted levels, leading simultaneously improved Jsc open-circuit voltage resultant all-PSCs. More importantly, regioregular (PZT-γ) has been achieve higher regiospecificity avoiding formation isomers during polymerization. Benefiting from more extended absorption, better backbone ordering, optimal blend morphology donor component, PZT-γ-based all-PSCs exhibit record-high power conversion efficiency 15.8% greatly enhanced 24.7 mA/cm2 0.51 eV.
