Abstract
Raw materials such as silicon and indium are insufficient as the photovoltaic generation grows up rapidly.Amorphous obtains an economy high because it is possible to deposit it to the glass with past 1/100 raw materials to use the vacuum deposition technology. Moreover, only about six % power generation efficiency enables the power generation efficiency of 10% by overlapping a different raw material of tandem type, and will become possible as much as 12% one of these days. The expansion with rapid United States first solar has been proven to the amorphous of the processing technology in future though sees. In the present study, the power generation efficiency is made to improve the basic technique of the semiconductor developed in Europe and to reach up to 10%, and the performance guarantee shows the content that enables 20 years. The color was enabled to be able to construct to the window and the roof as it was, and for the transparency to exist, and to prepare five kinds as materials for building construction, too. The one that the photovoltaic generation doesn't integrate with construction materials was also few the subsidy, requested harmony with the spectacle in France, and became the age of the design that secured the balance of the performance and construction.
