Development of Low-profile Dye-sensitized Solar Cell

November 15, 2016

Fujikura Ltd. (President and CEO: Masahiko Ito) is pleased to announce the development of a new dye sensitized solar cell, which is the most suitable for energy harvesting use.

Various types of sensor network systems are expected to be used for IoT worldwide and find many applications in different fields. To operate these sensor network nodes, energy harvesting devices will be the most effective than other common power sources since it does not require any field installation work or periodical replacement of batteries and consequently is an eco-friendly solution.

Last year, the company released dye-sensitized solar cells (DSSCs) as a light energy harvesting device with a high power conversion efficiency in low and scattered light conditions. As sensor network nodes are required to be smaller in size and thick to fit into various places, thinner in profile is also one of the challenges for DSSCs.

The company has successfully developed a DSSC with a wider cell area and 2.5 millimeter thickness, which is almost half that of the conventional products, by introducing a simple moisture-proof structure. Reference samples of this new version DSSC will be showcased together with conventional models at booth I12 and M19 in Energy Harvesting USA 2016 to be held on November 16 and 17.

We will further work on DSSCs as power sources of sensor network nodes used for IoT, which will be expanding rapidly in the near future, and continuously contribute to building an eco-friendly society.
