ABSTRACT: A novel strategy is proposed for controllable synthesis of lyaniline nano?bers by introducing high gravity into the interfacial polymerization system. During the polymerization of the aniline monomers, overgrowth and aggregation of the polyaniline nano?bers were e?ectively suppressed by virtue high gravity. By adjustment of high gravity levels, polyaniline nano?bers with various diameters can be obtained, and the diameter of the nano?bers becomes smaller as the gravitational acceleration increases (from 9.8 m/s to 78.4 m/s
2). By application of these materials as hole conductor media in quasi-solid-state dye-sensitized solar cells, it was found that the electrochemical behaviors are strongly dependent on the high gravity that is applied for the synthesis of the polyaniline nano?bers. Electrochemical impedance spectroscopy characterization indicates that both of the transport properties of charge in the bulk of the electrolyte and charge transfer on the counter electrode are a?ected by the diameter of the nano?bers. The quasi-solid-state photovoltaic devices employing the polyaniline nano?bers obtained under a high gravity level of 78.4 m/s
2
achieved energy conversion e?ciency of 1.375%, which is ~76% higher than that obtained under normalgravitational acceleration on Earth (9.8 m/s2). |
