Abstract

Electro-chemical polymerization has identified to be a facile and useful method for the preparation of electroactive and conducting polymer films, and capability of precise control of the film properties. With this strategy, a large number of conjugated polymers were developed as specific interface modification layers to meet the requirements from various electronic equipment. Here we report the synthesis of conjugated polymer film prepared by in situ electro-chemical polymerization as effective interface modification layer between ITO and ZnO in organic solar cells. By optimizing the polymerization potential to control accurately the thickness of conjugated polymer layer, the resulting devices show significantly enhancement of short-circuit current, with an optimized power conversion efficiency (PCE) of 14.9%. As a result, the reasonable interface modification strategy via electro-chemical polymerization seems to be able to bring a new design perspective for the development of high-performance organic solar cells.
