Progress in High Efficient Solution Process Organic Photovoltaic Devices : Fundamentals Materials Devices and Fabrication This book presents an important technique to process organic photovoltaic devices. The basics materials aspects and manufacturing of photovoltaic devices with solution processing are explained. Solution processable organic solar cells polymer or solution processable small molecules have the potential to significantly reduce the costs for solar electricity and energy payback time due to the low material costs for the cells low cost and fast fabrication processes (ambient roll to roll) high material utilization etc. In addition organic photovoltaics (OPV) also provides attractive properties like flexibility colorful displays and transparency which could open new market opportunities. The material and device innovations lead to improved efficiency by 8% for organic photovoltaic solar cells compared to 4% in 2005. Both academic and industry research have significant interest in the development of this technology. This book gives an overview of the booming technology focusing on the solution process for organic solar cells and provides a state of the art report of the latest developments. World class experts cover fundamental materials devices and manufacturing technology of OPV technology
