Solar Windows

Solar Windows from Sony that generate electricity

Sony conducts research on proprietary technologies that contribute to reduction of environmental impact so that they can be applied to new products and services, as well as manufacturing processes.

Sony is engaged in research on dye-sensitized solar cells, which use photosensitive organic dyes adsorbed on the porous electrode surface to convert light energy to electrical energy. Unlike conventional silicon-based solar cells, dye-sensitized solar cells do not require a large vacuum process machine in fabrication. Also, because they use a coating and a printing process, these cells allow low-cost fabrication and exert less of an impact on the environment due to the fact that they require fewer materials and less energy. Dye-sensitized solar cells have the additional advantage of providing excellent power generation especially in low-light situations, such as indoors or under cloudy skies. Depending on the dye color, these cells can even provide color variations.
Owing to these advantages, dye-sensitized solar cells are viewed as one of the most promising next-generation solar cell technologies.
