5-Bromo-4-(2-ethylhexyl)-2-thiophenecarboxaldehyde (EHThCHO-Br) is the intermediate that is used for the synthesis of low band-gap non-fullerene acceptors (NFAs). semiconducting materials bearing 5-bromo-4-(2-ethylhexyl)-2-thiophenecarboxaldehyde such as IEIC and IEIC-4F exhibit good thermal stability, strong absorption in the 500–750 nm region with great extinction coefficients.
Ternary non-fullerene polymer solar cell based on PBDB-T:ITCN:IT-M mixture gained a power conversion efficiency of 12.16% with increased short-circuit current density (Jsc) and open-circuit voltage (Voc) comparing PBDB-T:ITM-based device.
