Conducting Polymer/CdSe Hybrid as Bulk Heterojunction Solar Cell

Abstract

We report a hybrid system based on conducting polymer-semiconductor from poly(o-toluidine) doped with camphor sulfonic acid and cadmium selenide CdSe capped with trisodium citrate by physical mixing method. The influence of CdSe nanoparticles weight percent on the electrical properties of hybrid thin films have been investigated. The conductivity of the hybrid films increases with increasing CdSe content, and then decreases with excess CdSe content. This work introduces a novel bulk heterojunction solar cell from the poly(o-toluidine)/camphor sulfonic acid hybrid nanocomposite material and provides useful evidence apropos the optimum use of CdSe nanoparticles in conductive polymer-based optoelectronics.
