Development of Film Dye-sensitized Solar Cell with Industry’s Highest Efficiency of 8%
R&D Center of Sekisui Chemical in a joint project with Chief Researcher Shingo Hirose, Prime Senior Researcher Jun Akedo and others of the Advanced Coating Technology Platform Research Team, Advanced Manufacturing Research Institute (Research Institute Director: Masanobu Awano), of the National Institute of Advanced Industrial Science and Technology (AIST), have manufactured world’s first successful trial of film dye-sensitize solar cells (DSSC) in a room temperature process using aerosol deposition method, a high speed ambient temperature coating process used for ceramic materials, called AD method, without any needs to use high-temperature firing.
Use of minute particle adhesive mechanism through high-speed collision instead of heat has made the use of standard high temperature fired ceramic forming process unnecessary, making it possible to create film at room temperature. Adoption of this new technology would allow the manufactures to take advantage of Roll-to-Roll (R2R) processing method for improved productivity. The new technology makes it possible to produce slim, light, large-surface, flexible DSSCs at low cost, paving the way for realization of solar cells at any time and any place.
