NGK Invests in Perovskite Solar Cell Spin-off from Kyoto University

March 28, 2022

NGK INSULATORS, LTD. (“NGK”) has invested in EneCoat Technologies Co., Ltd. (Kyoto, “EneCoat Technologies”), which is involved in development of perovskite solar cells.

Perovskite solar cells (PSCs) are a new type of solar cell that uses a material with a crystal structure called perovskite. PSCs are thinner and more light weight than conventional crystal silicon solar cells and feature flexibility, enabling them to be installed and generate power on curved surfaces and other places impossible for crystal silicon solar cells until now. Furthermore, PSCs can maintain a relatively high-power generation efficiency even in low light illumination such as on cloudy days or with indoor lights and are therefore expected to accelerate carbon neutrality as next-generation solar cells.

EneCoat Technologies, a spin-off company from Kyoto University, is developing PCSs with greater power generation efficiency and durability and is engaged in establishing manufacturing process technologies to realize larger products that can be implemented in society.

NGK is using this investment to work on establishing production technologies that will contribute to improving the quality of PSCs, seeking to discover the possibilities of working with NGK’s various types of storage batteries*, and aiming to be a solution to achieve carbon neutrality.

The NGK Group regards carbon neutrality as a social issue to address under its mid- to long-term vision, NGK Group Vision: Road to 2050. We have also established a goal of “New Value 1000” to achieve net sales of 100 billion yen from new businesses in 2030. To do so, we established Corporate NV (New Value) Creation in April and are proactively advancing the creation of new products and businesses in such ways as collaboration with outside alliances. Going forward, NGK will continue to contribute to achieving carbon neutrality by 2050 by developing and providing various ceramic technologies and products.

* NGK’s various types of storage batteries:
 NAS batteries for power storage
 ZNB zinc rechargeable batteries
 EnerCera small, thin lithium-ion batteries
