Participation in NEDO's Green Innovation Fund Project/Development of Next-Generation Solar Cells
- Towards Developing Peripheral Materials to Reduce Costs and Improve Performance of Perovskite Solar Cells -

Mitsubishi Materials Corporation is pleased to announce its participation in the Green Innovation Fund Project/Development of Next-Generation Solar Cells (the Project) by the New Energy and Industrial Technology Development Organization (NEDO) as a company commissioned by EneCoat Technologies Co., Ltd. (EneCoat Technologies), which it finances through the MMC Innovation Investment Limited Partnership (our CVC).

A perovskite solar cell is a type of solar cell formed by applying a layer of perovskite crystal* on a substrate, and it is expected to become widely used as the next-generation solar cell because it is lighter than the crystalline silicon solar cells commonly used at present, enables the thickness to be reduced to about 1/100, and can be folded or bent for installation in various places. EneCoat Technologies, a startup originating from Kyoto University, is working on its development. EneCoat Technologies is also developing a low-lead solar cell by replacing the lead contained in perovskite solar cells with an alternative material.
We financed EneCoat Technologies in May 2020 through our CVC and we are examining collaboration with them regarding technologies that will contribute to improving the durability of perovskite solar cells and development of the peripheral materials required for eliminating lead.

In the course of these developments, EneCoat Technologies has recently been selected for the Project based on the theme "development of technology for the practical application of perovskite solar cells featuring a high degree of installation freedom." Towards adopting solar power generation in places where installation of the existing types of solar cells has not been possible, such as for example on the roof of a small factory or a wall of a building with low load capacity, the Project aims to achieve the practical application of perovskite solar cells, which not only realize weight reduction and provide sufficient flexibility for installation on curved surfaces of buildings but also compare favorably with existing types of solar cells in terms of performance including conversion efficiency and durability. We participate in the Project as a company commissioned by EneCoat Technologies and work on the development of peripheral materials to reduce costs and improve performance for the purpose of facilitating the wide use of perovskite solar cells.
