Fujikura Develops Next-generation Solar Battery

Fujikura, Ltd. announced on Friday that it developed large area module panel of dye-sensitized solar cell (DSC). The firm declined internal resistance of elemental device throughout its forming power collection wiring on the surface of transparent electrode, applying its self-developed technology of glass substrate with low-resistance transparent conductive film and high conductive printing paste, etc. Fujikura adopted screen printing during the production process and solved the problems of leak and volatile of electrolyte through adoption of solidified electrolyte which has ion liquid without volatile. Fujikura wants to put into practical use of the panel throughout outdoor exposure tests, etc. Multicrystalline silicon is mainly used to Fijikura’s solar battery, which is currently being put into practical use as a raw material. The supply and demand is tight thanks to sharp expansion of the solar battery market. The material price has the tendency to rise. On the other hand, DSC solar battery is low-cost and next-generation product without vacuum process and toxic substance. Fujikura developed the module of its panel size of 1,190×840 millimeters by structure of fitting together 16 units of the cell with 410×140 millimeters. Further, Fujikura developed the transparent conductive glass forming fluorine dope tin oxide film continuously after forming indium tin oxide on the glass substrate in 2003. The technology, etc. promoted development of the next-generation solar battery.
