NSK's Exhibit at PV EXPO 2015-The 8th International Photovoltaic Power Generation Expo

Exhibit of Dye-Sensitized Solar Panels with Superior Hue, Transparency and Design

NSK Ltd. (NSK; Headquarters: Tokyo, Japan; President and CEO: Norio Otsuka) today announced that it has developed an electrolyte with greater transparency than conventional units, thereby making it possible to produce dye-sensitized solar cell (DSSC) that feature a superior hue, transparency and design. Electrolytes are constructional elements that carry electrons between the pigment and electrodes of DSSC, thereby playing a critical role in the performance of solar cells. NSK will exhibit this newly developed product at the PV EXPO 2015-The 8th International Photovoltaic Power Generation Expo from Wednesday, February 25 to Friday, February 27 at Tokyo Big Sight in Tokyo. In these ways, NSK is contributing to the realization of the Internet of Things.

DSSC are different from mainstream silicon and compound semiconductor solar cells in that they can contribute to hue and design. Also, DSSC are better than conventional solar cells at generating power under conditions of low incidence angle dependency and low illumination. They are the next generation of solar cells with potential applications such as use, for example, in power supply for sensors used to light interior posters and stained glass.

NSK developed this new electrolyte that has a greater level of transparency than conventional units by applying electrochemical technology fostered through its development of core material technology and organic material technology fostered through its development of lubrication technology as applied to development to DSSC. In carrying this out, NSK has made it possible to produce DSSC panels that provide superior hue, transparency and design.

Features of the Newly Developed DSSC Panels

(1) Improved Hue
Using this kind of electrolyte that has greater transparency makes it possible to produce solar panels that have hues closer to real colors than that of conventional panels.
(2) Improved Transparency
This new technology makes it possible to produce colorless solar panels with a greater level of transparency compared to conventional technology (iodine-based materials).
(3) Greater Freedom of Design
This new technology also makes it possible to use printing technology to make designs of the desired size in the production of solar panels.

Application Examples

NSK is committed to research that will further improve conversion efficiency and durability. In addition, NSK will continue to explore application possibilities related to the Internet of Things, such as stand-alone power generation elements used in sensor network terminals and battery chargers for handheld devices.

NSK's Commitment to Renewable Energy Technology

As a mechanical components manufacturer, NSK is contributing to the advancement of renewable energy technology by leveraging its Motion & Control technology toward the development of bearings used in solar cell manufacturing devices as well as large bearings for wind power. NSK is committed to contributing to the development of a sustainable society through application of its core technology to state-of-the-art renewable energy technologies through the development of bearings and other mechanical components.
