NGK backs roll-to-roll perovskite solar cell startup
Japanese ultrathin battery maker NGK Insulators has invested in a startup developing perovskite solar cells.
EneCoat Technologies Co., Ltd is a spin-out of Kyoto University developing perovskite solar cells (PSCs) with higher efficiency and durability along with a roll-to-roll manufacturing process technology to reduce production costs.
Solar cells built with perovskite materials 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.
These cells 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.
NGK is already heavily involved with solar cells for sensors in the Internet of Things through its EneCera lithium battery business and NAS battery storage. NGK is using this investment to work on establishing production technologies that will contribute to improving the quality of PSCs to potentially work with NGK’s various types of storage batteries.
