A solution-processed high performance organic solar cell using a small molecule with the thieno[3,2-b]thiophene central unit.


A solution processed acceptor-donor-acceptor (A-D-A) small molecule with thieno[3,2-b]thiophene as the central building block and 2-(1,1-dicyanomethylene)-rhodanine as the terminal unit, DRCN8TT, was designed and synthesized. The optimized power conversion efficiency (PCE) of 8.11% was achieved, which is much higher than that of its analogue molecule DRCN8T… (More)
