In his research at PNNL, Dr. Polikarpov is focused on thin film solar cells and organic light-emitting devices (OLEDs). He demonstrates the principles of rational design of organic ambipolar host materials to build high power efficiency OLEDs. His work on photovoltaics has lead to improved efficiency in CdTe-based solar cells as a result of implementing multilayer window structures. He currently explores new absorber and window materials for thin film solar cells. Dr. Polikarpov has co-authored over 20 research publications.
