Organic Semiconductor Devices for Light Detection

Dr. Kublitski obtained his master's degree at Paraná Federal University in Brazil. In 2016, he moved to Germany to join the group of Prof. Dr. Karl Leo at the Dresden Integrated Center for Applied Physics and Photonic Materials, where he pursued his PhD. During this period, he worked on organic photodetectors (OPDs), investigating fundamental mechanisms, such as dark and noise current generation and photomultiplication in narrowband devices. During his PhD, Dr. Kublitski also contribute to several projects involving organic solar cells and properties of organic semiconductor materials, where charge-generation, charge-transfer and band-gap engineering were target. These projects resulted in over 15 important publications. Currently, he is a postdoctoral fellow in the same group. His research topics go towards the development of new OPD structures, formation of trap states and their relation with noise current in optoelectronic devices as well as charge transport.
