제목 Synthesis and characterization of water-soluble fullerene derivatives as interfacial materials for organic solar cells
초록 Interface engineering in organic solar cells is one of the strategies for high performance devices. Recently, fullerene derivatives for inverted organic solar cells have been studied due to their high electron mobility, tunable energy level and improvement of electrical contact. Especially, water-soluble fullerene derivatives as interfacial layer have some advantages; water solubility, well-matched energy level by induced interface dipoles and accomplishment of tandem cells. In this study, we synthesized water-soluble fullerene derivative having amine groups with high-yield amination reaction methods. The synthesized amino fullerene can be dissolved in polar solvent, preventing intermixing of the multilayers. The structural, optical, thermal and electronic properties of the fullerene derivative was characterized by 1H-NMR, UV-vis spectroscopy, TGA/DSC and Kelvin probe measurement. Finally, the effects of using the interfacial layer in the organic solar cells will be discussed.
