Japanese Printing Company Invents Independent Solar Power Lighting Lamps

On September 12, 2012, the Japanese photo printing company launched the “AKARIE,” an independent power lighting device using a dye-sensitized solar cell, and the printing company has since acquired a new “secondary industry”.

The dye-sensitized solar cell works by adsorbing a pigment on the surface of a titanium oxide electrode and converting the light energy absorbed by the pigment into electric energy. New products can depict colorful patterns. AKARIE uses the “EneLEAF” dye-sensitized solar cell developed jointly by the Japanese photo printing and the Shimane Industry Technology Center.

AKARIE is a stand-alone power system that is powered by EneLEAF assembled in the airframe during the day and illuminated by a built-in LED at night. It combines the three functions of power generation, storage and lighting, so no electrical construction is required for installation. It is a transparent product made of glass material for a two-electrode substrate. The design can be customized. Although the corresponding design and weather will be different, on sunny days, it can be lighted for about 15 hours after charging for about 2 hours. The brightness is about 10 Candela.

The dimensions are 200 mm wide x 200 mm long x 85 mm high. The weight is 3.7 kg. The price is 210,000 yen. Japanese photo printing is expected to have certain demand in the food and beverage industry and strives to reach 200 million yen in 2014 sales.
