Mitsubishi Chemical Corporation and Dacheng Construction Co., Ltd. announced on March 24, 2014 that the two companies have jointly developed a building facade unit that uses organic thin-film solar cells to generate electricity, and will soon launch an empirical test aimed at performance evaluation. Mitsubishi Chemical has been working on the development of coating type organic thin-film solar cells and achieved a conversion efficiency of 11.7%, which is the highest level among organic products. A coating type organic thin film solar cell is manufactured by coating an organic semiconductor material. Therefore, if a thin material such as plastic and metal is used as a substrate, a lightweight flexible solar cell can be obtained. Because it can also be produced on a three-dimensional surface, the field of installing or installing solar cells is expected to increase substantially. The building exterior unit developed this time uses the technology and experience related to exterior materials owned by Daesung Construction. It not only pursues the diversified appearance and color required by the building, but also can be easily replaced as the building's service life increases. To increase the use of photovoltaic power generation in urban areas where solar panel installation space is limited, besides installing on the roof and roof surfaces, it is also an effective method to provide power generation functions such as external walls and windows. Dacheng Construction is currently constructing the “ZEB (Zero Energy Building) Empirical Building†in the technical center of Totsuka-ku, Yokohama City. The two companies will use newly developed solar cells on the exterior wall of the building to verify their performance and performance. Construction materials and durability.
