Abstract

All-Polymer Solar Cells

In article number 2500148, Bin Liu, Sang Young Jeong, Xugang Guo, and co-workers develop a series of bithiophene imide (BTI)-based polymer donors with high number-average molecular weights ranging from 120.3 to 145.5 kDa, offering improved molecular aggregation property and optimized P_D:P_A miscibility. In the image, the iconic Shenzhen Civic Center serves as the backdrop, with the device structure of an all-polymer solar cell extending from it. Above the device lies PBTI-OD, the polymer donor that contributes to the performance of all-polymer solar cells.

基于双噻吩亚胺的高分子量聚合物供体用于高效耐用的全聚合物太阳能电池。抛光工艺。12/2025)

文章编号2500148，刘斌，郑尚永，郭旭刚等人开发了一系列基于双噻吩亚胺（BTI）的聚合物供体，具有高数平均分子量（120.3 - 145.5 kDa），改善了分子聚集性能，优化了PD:PA的混相性。在图像中，标志性的深圳市民中心作为背景，全聚合物太阳能电池的设备结构从它延伸出来。该装置的上方是PBTI-OD，这是一种聚合物供体，有助于提高全聚合物太阳能电池的性能。
