Abstract

original image

Bound for greatness: A sulfhydryl-capped photoactive polymer is synthesized and covalently bound to the anode consisting of a thin layer of gold on ITO by using self-assembly. A high power conversion efficiency is achieved for the device due to a reduction of the energy barrier between the anode and the active layer.
