A ternary organic solar cell with 15.6% efficiency containing a new DPP-based acceptor

A new non-fullerene small molecule (MPU6) containing thienylethynylselenophene bridges, has been studied as an acceptor along with PC 71 BM and TDTBTA as a donor in ternary solution-processed bulk heterojunction polymer solar cells, showing a PCE of 15.60%.
