Showa Shell Sekiyu to start joint project on a large-scale solar power generation plant with Niigata Prefecture
Showa Shell Sekiyu K.K. (Chairman: Shigeya Kato, Headquarters: Daiba, Minato-ku, Tokyo) has decided to construct a large-scale solar power generation plant with Niigata Prefecture as a part of a subsidized project by the Prefecture and a promotion of new energies by New Energy Promotion Council. CIS thin-film photovoltaic modules produced by Showa Shell's 100% subsidiary, Showa Shell Solar K.K. (President: Shigeaki Kameda, Headquarters: Daiba, Minato-ku, Tokyo), will be used for the plant.

About Showa Shell Solar K.K.
Showa Shell Solar developed leading technology in manufacturing thin-film CIS photovoltaic modules (product name: "SOLACIS") and started commercial production at the first plant ("Miyazaki Plant" , annual production capacity 20MW) in 2007. This April, the second plant ("Second Miyazaki Plant" , annual production capacity 60MW) was completed, and commercial production started in June. At Atsugi Research Center, research and development of leading production technology for the third plant is conducted. In September, the company announced to start the construction of the third plant with annual production capacity of 900MW.
About CIS photovoltaic modules
CIS PV modules are leading edge solar panels, composed of Copper, Indium and Selenium, without the use of silicon. CIS modules are generally regarded as the most promising technology among all the thin-film photovoltaic applications. CIS modules have already achieved the highest efficiency level among the thin-film photovoltaic applications, and the potential is high for further improving the conversion efficiency with this technology. Compared to crystalline silicon photovoltaic modules that are the current mainstream, CIS modules can be produced at lower cost with fewer raw materials required and approximately half the manufacturing process steps. In addition, CIS modules are environmentally friendly products with a drastically reduced energy payback time (period required for the recovery of energy consumed during manufacturing through power generation), and Showa Shell's CIS modules do not contain toxic materials such as lead and cadmium.
