Abstract

In this work, we have successfully demonstrated that device performance of Bulk Heterojunction (BHJ) Hybrid Solar Cells can be greatly enhanced by optimization CdSe Quantum Dots (QDs) loading in photoactive layer. Optimization was reached by various blend concentration, the ratio (w/w) of donor to acceptor was varied between 80% and 90% of CdSe QDs weight content. An optimum QDs loading was found at 86 wt.%, resulting high photo conversion efficiency (PCE) of 3.1 % The efficiency enhancement is attributed to optimum photon absorption and electron transport leading to an increased short-circuit current density of devices.
