Sensitized type solar cells available

Japan Peccell Technologies Inc. successfully developed about 12cm × 12cm, the output voltage above 4V, 0.1A output current over-type dye-sensitized solar cells, starting in 2006 suppliers of industrial samples. The company is based on Yin-Tung University, Graduate School of Yokohama Miyasaka Professor Li as the central risk of the establishment of enterprises, in addition to the company’s investor Yam Tong University and Miyasaka, there are islands of chemicals and Showa Denko, Fujimori industries.
To promote the dye-sensitized solar cells use and development objective is to achieve output voltage lithium-ion rechargeable battery level. In order to enhance the output voltage, in the 12cm square panel of six batteries in series the unit, the unit is said to seal in the isolation of the development of materials encountered many difficulties. Photoelectric conversion efficiency of 4.3% ~ 5.2%.
12cm square of the current solar panel production cost of about ¥ 700 (about 54 yuan). To switch to other alloys used in electrode materials to replace the high cost, such as platinum, the lower production costs. There is no alloy composition of the public. In 2006 before the supply of industrial samples, production costs will be reduced to ¥ 300 (about 23 yuan) around. In order to further cut costs, also plans by changing the synthesis methods, 1g to about ¥ 100,000 (about 7700 yuan) of the expensive pigment to about ¥ 20,000 (about 1500 yuan) / g.
Sharp metal roof will be listed on the integration of solar cell modules
Sharp announced on September 14, October 1 from the beginning of the listing without frame units can be directly over the roof of the “metal roof of a solar cell module body.” Divided into 5-watt type “NE-53Y1N” and 4-watt type “NE-38Y1N” two. Price for ¥ 26,880 (about 2070 yuan) and ¥ 22,050 (about 1700 yuan). Monthly production target of 2 million units.
Mainly oriented to Yamagata cap surrounded by cone-shaped roof and the roof installation. The use of steel roofing and solar modules to form one, direct coverage of the roof of the “cover construction method.” As the need to set up as the original bench, from the first class will be able to install the module roof Department. In particular, it is surrounded by cone-shaped roof, the largest installed capacity can be raised by 2 into.
In addition, the roof opened as there is no need can be completed as construction, it reached the lower construction costs and shorten the duration of the purpose of angle can also be expected to reduce processing cost. The design of the roof materials and solar cells using the separation may be based on the structure need to be replaced in the event of disasters and accidents are easy to maintain.
Roofing production Japanese JFE Steel’s “wing-watt.” With light weight, and corrosion characteristics of steel plate Galbarium (from aluminum, lead and silica sub-components of the plating alloy steel) for high durability coating. In addition, use of anti-seismic and wind design.
