摘　　要：A new photoresponsive D--A dye, mPS, has been designed and synthesized. Compared to the parent dye PS, IPCE values in the region from 400 nm to 560 nm was greatly improved upon changing the attaching group from the p- position to the o- position of the p-conjugation bridge. A solar cell based on mPS generated a remarkably high overall yield of 5.4% under irradiation of 80.0 mW cm-2 white light from a Xe lamp. Compared with PS, the overall yield ?increased by 64%.A new photoresponsive D--A dye, mPS, has been designed and synthesized.
