ABSTRACTElectrochromic (EC) devices are able to vary their throughput of visible light and solar energy by the application of a voltage. They are of much interest for “smart” windows in buildings and are able to create energy efficiency, occupant well being, and security. This paper gives a survey over oxide-based EC device technology and also presents some recent advances regarding EC thin films of mixed metal oxides, nanoparticle-containing electrolytes to join these films, and metal-based transparent electrical conductors needed to apply the voltage.

Novel Strategy

In this study, a novel strategy for preparation of Cu2(MII)(MIV)S4 thin films was creatively proposed. Three light absorption materials Cu2MnSnS4, Cu2ZnSnS4 and Cu2ZnGeS4 were successfully synthesized based on combustion method. It was found that the combustion synthesized powder is mainly consist of several metal oxides. The band gap energy of Cu2MnSnS4, Cu2ZnSnS4 and Cu2ZnGeS4 are determined to be 1.3 eV, 1.49 eV and 2.15 eV, respectively, showing a promising application on thin film solar cells. According to our experiment results, the combustion method was confirmed to be an efficient tool to synthesize various Cu-based absorber materials by using a post-sulfurization process, which provides a new view for fabrication of high-efficient low-cost photovoltaics.

Chromogenic materials and devices allow the construction of glazings whose throughput of visible light and solar energy can be varied depending on the application of an electrical voltage or temperature. These glazings are of much interest for energy efficient buildings and are able to create energy efficiency along with indoor comfort. This paper outlines the basics of electrochromic and thermochromic technologies with foci on functional principles, materials, device and manufacturing technology, and selected results from research and development.
