제목 Investigation of the initial thermal degradation in Organic Solar Cells
초록 Many studies about the causes of thermal degradation in Organic Solar Cells(OSCs) have been researched, however, different D/A materials, device structure, and annealing conditions have been used for the studies. In order to overcome the thermal degradation defects, we need to know the precise cause of thermal degradation objectively. In this study, several series of inverted OSC were fabricated and thermally aged in dark and inert conditions. All devices demonstrated a PCE decrease at certain temperatures(Td), even in the short term (10 min). AFM results and pre-annealing test, we figured out that the performance of OSCs is not affected by thermal stress at Td. Dark current test and Light intensity dependence results show that current decrease is originated from leakage current and recombination. To check the electrical properties of OSCs, we will employ UPS for work function changes and EIS for diode resistance.
