Organic solar cells fabricated from PhI-based polymers and DPP-based small molecules
【摘要】:正Organic solar cells have been a rather active area in organic electronics due to their potential applications to afford low-cost and green energy. In order to obtain high efficiency materials, we choose phthalimide (PhI) and diketopyrrolopyrrole (DPP), respectively, as basic units to construct a series of copolymers and solution-processed small molecules. The effects of intermolecular and intramolecular interactions on photovoltaic performances were investigated.
