Dependence Of The Characteristics Of Organic Solar Cells On Cathode Polymer Interface
Authors : Ourahmoun O. . Belkaïd M.s. .
Abstract
Increasing energy assumption and rising energy prices in the world forces to look for energy alternatives, one of the most promising is the photovoltaic energy. Solar cells made from organic materials are particularly attractive because they are relatively easy to produce, structurally flexible, and can be applied to large areas at low cost. Fill Factor is a more sensitive parameter compared to open-circuit voltage (Voc) and shortcircuits current density (Jsc). This FF depends also on the thickness of the active-polymer layer, on the morphology of the cathode-polymer interface and on temperature. In this article, we study the dependence of fill factor (FF) on different parameters in organic bulk heterojunction solar cells.
