제목 The Change of Interfacial Property through Modifying a Cathode Buffer Layer in Polymer Solar Cells
초록 A simple modification of cathode buffer layer was developed to change the interfacial property in polymer solar cells (PSCs). In this presentation, 2-hydroxypyridine (2OH-Py) and 4-hydroxypyridine (4OH-Py) were introduced between a cathode and an active layer as a cathode buffer layer in PSCs, which showed the difference of interfacial dipole by utilizing different position of hydroxyl group in pyridine. It was found that the work function of 2OH-py and 4OH-py is -3.92 and -4.23 eV, respectively. This data is caused by the different interfacial dipole at the cathode interface. As a result, the power conversion efficiency (PCE) of the device based on 2OH-py is higher than the PCE of the device with 4OH-py.
