Printing Solar Cells

Close

This project developed new materials and solar cell designs with enhanced performance that significantly improve the efficiency and durability of organic photovoltaic (OPV) solar cells.Key resultsDuring the three year program, the consortium synthesised over 85 new materials divided into p-type materials (fifty nine polymers and nineteen small molecules), and seven new n-type materials. Of these 85 new materials 20 were rejected as they failed to pass the synthetic stage gate parameters, a further 12 were rejected as they failed to pass optoelectronic stage gates. A further 29 were rejected as they failed to pass initial device performance stage gates. Organic photovoltaics (OPVs) have emerged as a dynamic new technology that promises a low-cost way of mass-producing solar cells through the use of commercial printing processes.
