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.

Polymerized Small‐Molecule Acceptors for High‐Performance All‐Polymer Solar Cells

Angewandte Chemie International Edition, Journal Year: 2020, Volume and Issue: 60(9), P. 4422 - 4433

Published: Aug. 28, 2020

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.

Precisely Controlling the Position of Bromine on the End Group Enables Well‐Regular Polymer Acceptors for All‐Polymer Solar Cells with Efficiencies over 15%

Advanced Materials, Journal Year: 2020, Volume and Issue: 32(48)

Published: Oct. 29, 2020

Recent advances in the development of polymerized A-D-A-type small-molecule acceptors (SMAs) have promoted power conversion efficiency (PCE) all-polymer solar cells (all-PSCs) over 13%. However, monomer an SMA typically consists a mixture three isomers due to regio-isomeric brominated end groups (IC-Br(in) and IC-Br(out)). In this work, two isomeric are successfully separated, regioisomeric issue is solved, polymer acceptors, named PY-IT, PY-OT, PY-IOT, developed, where PY-IOT random terpolymer with same ratio acceptors. Interestingly, from absorption edge gradually redshifts electron mobility progressively increases. Theory calculation indicates that LUMOs distributed on entire molecular backbone contributing enhanced transport. Consequently, PM6:PY-IT system achieves excellent PCE 15.05%, significantly higher than those for PY-OT (10.04%) (12.12%). Morphological device characterization reveals highest PY-IT-based fruit absorption, more balanced charge transport, favorable morphology. This work demonstrates site polymerization SMAs strongly affects performance, offering insights into efficient all-PSCs.
