Research on new solutions in organic electronics is conducted by scientists from the Department of Molecular Physics at TUL: Prof. Wojciech Pisula and Dr. Tomasz Marszałek together with Dr. Jasper Michels from Mainz. Together, the researchers managed to link the theoretical model with experimental results.
As Dr Eng. Tomasz Marszałek, winner of the FIRST TEAM program, co-author of the publication, explains,: As part of the cooperation, our German partner developed a theoretical model showing how the application process affects the quality of thin semiconductor layers. We have been able to experimentally confirm the use of this model. We have thus demonstrated that the size and shape of semiconductor crystals determine their subsequent applications, e.g. in thin film displays, photovoltaic cells or electronic integrated circuits.
There is a very fast growing interest in organic electronic devices, which have many advantages compared to traditional silicon. First of all, they can be printed on a large scale. The experience of the Lodz organic electronics research group so far has confirmed that the performance of the manufactured devices is strongly dependent on the quality of thin semiconductor layers.
