Surprising Effects upon Inserting Benzene Units into a Quaterthiophene‐Based D‐A Polymer–Improving Non‐Fullerene Organic Solar Cells via Donor Polymer Design
Source abstract
Abstract
Benzene units are inserted into the backbone of a quaterthiophene-based polymer named PffBT4T, and the resulting polymer, PffBT4T-B, exhibits remarkably tight alkyl chain interdigitation, which can expel the ITIC-Th molecules from the polymer domains thus forming more pure and crystalline ITIC-Th domains. As a result, PffBT4T-B-based non-fullerene organic solar cells achieve a high power conversion efficiency of 9.4%.
