P4T2F-HD belongs to the polythiophenes (PTs) family with either fluoro or alkyl groups on the main backbone of the polymer.
Fluorination can promote stronger interchain interaction to enhance polymer crystallinity. While P3HT can form completely mixed bulk heterjunction (BHJ) films with non-fullerene acceptors, P4T2F-HD has relatively low miscibility with them, i.e. Y6-BO (BTP-4F-12), which enables the blending active materials to form desired packing and nanoscale phase separation morphology for efficient OSCs.
Record device performance with PCE of 13.65% was achieved by using an active layer materials with P5TCN-F25 as the polymer donor and Y6-BO as the acceptor by the following device structure with excellent storage and thermal stability.
Device structure: ITO/ZnO/C60-SAM/P4T2F-HD:Y6-BO/MoO3/Ag .
