Outline of Final Research Achievements

In this study, we have developed a new method for obtaining the trap density function based on photo-carrier extraction experiments using a linearly increasing voltage (photo-CELIV). The photo-CELIV technique was originally developed in order to determine the time and field dependence of the hopping conduction mobility for charge carriers generated by a light pulse. In most CELIV studies, CELIV data are analyzed based on the assumption of an effective mobility and traps are not explicitly considered. We applied this technique to determine the trap density function of the photovoltaic cell composed of P3HT:PCBM bulk heterojunction. The gaussian-type trap density with an average energy of 0.087eV was obtained.
