Status and Potential of Organic Solar Cells — •Moritz Riede — Institut für Angewandte Photophysik, Technische Universität Dresden, Germany

Organic solar cells have attracted increasing attention in recent years and their development has reached a stage at which several companies are preparing to make them commercially available. Despite lower power conversion efficiencies than their inorganic counterparts, organic solar cells have the potential to become a low-cost alternative, due to low material consumption, simple processing methods as well as the possibility for flexible and light-weight devices. This presentation summarises important recent developments and describes how the synthesis of new organic semiconductors with tailored properties, tuning the morphology of the active layers, adaption of inorganic device concepts like tandem devices, and improved light incoupling have lead to major improvements. It further outlines the current research strategies for improving the basic physical understanding, obtaining higher device efficiencies and lifetimes. Finally, based on the investigated large area production technologies it is shown that the cost can potentially be very low and organic solar cells could address large markets.
