    摘要: A fullerene derivative for electron acceptor is disclosed. Introducing a benzylalkyl group into the fullerene derivative can increase the affinity of the fullerene derivative with electron donors, and introducing an alkyl group into the fullerene derivative can increase the solubility of the fullerene derivative with an organic solvent. In addition, an organic thin-film solar cell and a method of manufacturing the same are further disclosed. An annealing process can be employed to improve the crystallization and to reduce the phase separation state of a photoactive layer that is formed by the fullerene derivative and the electron acceptor. Thereby, the fullerene derivative is facilitated to enhance the solar energy to electricity conversion efficiency of the resultant organic thin-film solar cell.
