Aggregation state tuning via controlling molecular weights of D–A1–A2 type polymer donors for efficient organic photovoltaics

Autor: Shanlu Wang, Tianyi Chen, Shuixing Li, Lei Ye, Yuang Fu, Xinhui Lu, Haiming Zhu, Lijian Zuo, Minmin Shi, Hongzheng Chen

Publikováno v: Journal of Materials Chemistry A. 11:6997-7005

A polymer donor with a D–A1–A2 type structure was developed, whose aggregation state was tuned by molecular weight control, finally leading to over 15% power conversion efficiency.

Bridging the inter-grain charge transport via organic semiconductors for high-performance thickness-insensitive perovskite solar cells

Autor: Yuying Cao, Fei Wu, Chang Xu, Haotian Wu, Shuixing Li, Xinru Wang, Tianyi Chen, Boyu Peng, Hanying Li, Hongzheng Chen, Lijian Zuo

Publikováno v: Materials Chemistry Frontiers. 7:1803-1812

The solution-processability of perovskite solar cells (PVSCs) reduces the production cost, but renders a multi-crystalline film with a large number of grain boundaries, which hinders the charge transport and induces defects.

Mapping polymer donors with a non-fused acceptor possessing outward branched alkyl chains for efficient organic solar cells

Autor: Qing Shen, Chengliang He, Shuixing Li, Lijian Zuo, Minmin Shi, Hongzheng Chen

Publikováno v: Journal of Materials Chemistry A. 11:3575-3583

A fully non-fused electron acceptor BO-4T with condensed π–π stacking and obvious face-on orientation was developed. The D:A pairing principles for NFREA-based OSCs were explored and PM6 works the best with BO-4T.
