Controlling organic semiconductor band gaps by electron-acceptor fluorination

Researchers synthesized a fluorinated electron-acceptor for use in organic semiconductors. The high electronegativity of the fluorine substituents enhanced the electron-accepting properties of the widely used electron-acceptor. The power conversion efficiency of a thin film solar cell based on the fluorinated product was shown to be significantly higher than that of a cell containing an unmodified analogue. The synthesized material could be applied in thin film organic solar cell devices.
