Abstract

A method of fabricating an organic photovoltaic device. The method includes providing a first electrode which by applying a layer of conductive material onto a transparent substrate. The conductive material forms the first electrode. The method also includes placing an active layer of organic photovoltaic material on top of the first electrode. The active layer is configured to convert photonic energy into electrical energy. Placing an active layer of organic photovoltaic material includes placing an active layer of organic photovoltaic material having ferroelectric dipoles dispersed therein. The method further includes applying a second electrode on top of the active layer of organic photovoltaic material.
