The displacement of CO2 emissions by renewable sources of energy critically depends upon the development of low-cost and widely accessible routes to clean energy generation. Solution processed organic solar cells based upon nanostructured donor-acceptor heterojunctions are currently attracting significant interest for this purpose. Substantial advances in the performance and efficiency of organic photovoltaic devices have been reported in recent years. This project focuses on three key challenges for the translation of these lab-scale efficiencies into, low cost, scalable photovoltaic device technologies. Specifically, the three aims of this project are: (i) development of indium and PEDOT -free transparent conducting electrodes which are compatible with high device-module efficiencies and cost effective scale up and (ii) development of new synthetic methods for the scale-up of high-performance organic semiconductors and (iii) the implementation of these materials into OPV modules fabricated employing processing methodologies compatible with high through put, low cost manufacture. To address these aims we have assembled a highly multidisciplinary team comprising academics and industries with world-leading expertise in inorganic oxide electrode film deposition, polymer synthesis, processing, thin-film printing, functional characterization, nanomorphology, device physics and manufacturing. This proposal builds directly on the substantial advances made in our Stage 1 Grand Challenge in Nanotechnology and Energy program funded by EPSRC, targeting the demonstration of a commercially viable production process for OPV devices with enhanced stability and reduced cost
