英文摘要: Alcohol-soluble fullerene derivatives with different functional groups will be designed and synthesized for the applications as cathode buffer layer and acceptor materials in fabricating the inverted structured organic solar cells (OSCs) by “one-step” method with environmental-friendly non-halogenated solvent. Suitable conjugated polymer donor materials, which is solubale in environmental-friendly non-halogenated solvent, will be selected for matching with the fullerene derivative acceptors. The working mechanisms of the fullerene derivatives as acceptor and cathode buffer layer in the OSCs will be studied via atomic force microscopy (AFM), scanning kelvin probe (SKP), photoelectron spectroscopy (AC2), contact angle and surface energy measurement, space charge limited current measurements (SCLC), organic field effect transistor (OFET), X-ray photoelectron spectroscopy (UPS), femtosecond transient absorption (TA) spectroscopy measurements and so on. The green, environmentally friendly organic solar cells can be achieved. This project is in accord with the new direction of energy development and environmental protection in the international society.
