In this talk, the development of organic conjugated materials, which are applicable to various solar cell devices, will be discussed. To design and synthesize appropriate organic materials for the solar cell application required to consider their optical and electrical properties in addition to the energy levels. In the case of organic photovoltaic (OPV), the bandgap and energy levels for the electron donors and electron acceptors should be concerned to optimize the photon absorption and charge separation, while the charge mobility is essential for the efficient charge collection. The p- and n-type organic semiconductors were synthesized and used as the photoactive materials for OPVs. At the same time, the p-type materials were also employed as the hole-transport materials in quantum dot and perovskite solar cells. |
