Research Project Outline
Target of this research project is the realization of organic solar cells showing conversion efficiency of 15%. In order to accomplish this target, we establish the bandgap science for organic semiconductors, such as eleven nines (11N) high purification, pn-control by doping, built-in potential formation, ohmic junction formation, precise evaluation of semiconductor parameters, together with the science of excitons and organic/inorganic heterointerfaces.
