The Polyaniline thin films undergo electrochromatic color change between oxidation and reduction state. First, an in-situ cyclic voltammetry method is used to monitor the potential and current peak on oxide/redox change, while measuring the transmittance change to calculate the electrochemical efficiency. Secondly, the chemical-synthesized polyaniline is spin-coated on the semi-transparent thin-film solar cell, which provides the electricity for the electrochromaticity of the polyaniline. The color change process and the solar cell efficiency are observed. On the other hand, the electrochemical deposition of the polyaniline on the solar cell can be realized by the electricity of the solar cell itself. The resultant polyaniline can do solar-electrochromaticity as well. In summary, polyaniline thin-film can be produced by low-cost electrochemical deposition and chemical synthesis methods. The thin film has the desired optical modulation characteristics and can be used with the solar cell. In the future, it has big potential in the applications of windows of the green energy building.
