Organic & Perovksites photovoltaic devices as other organic electronics (OLEDs, sensors, etc.) have the promise to provide lightweight, flexible alternatives to traditional, rigid semiconductor technologies and other inorganic thin film PV technologies. The principle of organic and Perovskites semi-conductor technologies will be presented with a particular focus on photovoltaic applications. The goal of the course is to give students awareness of the largest alternative form of energy and how organic/polymer and emerging Perovskites solar cells can harvest this energy. The course provides an insight into the theory behind these technologies and describes the three main research areas within the field i.e. materials, stability and processing. The main challenges of this emerging industry will be highlighted in order to illustrate the path from research to market.
