Panasonic Holdings announced on the 20th that it will begin full-scale mass production of next-generation “perovskite solar cells” in April 2029. Production will take place at a facility to be established in Nagahama City, Shiga Prefecture, Japan. Thinner than conventional solar panels, the product is integrated with building material glass and is expected to be installed on building windows and walls.
The product to be mass-produced measures 1.8 meters tall and 1.2 meters wide, and its product name is “ENEFACE.” It is manufactured by coating raw materials onto glass plates like ink, and its distinguishing feature is that the design can be changed according to customer requests. The company aims for adoption in commercial buildings and public facilities and is accelerating sales efforts with developers and local governments.
Perovskite solar cells are lighter and thinner than silicon-based types, so there are fewer constraints on installation locations. The company has also indicated a target of around 2030 for mass production of a type sandwiched between glass.
Waste disposal is an issue for widespread adoption. Panasonic Holdings plans to launch a recycling business for glass-integrated products in fiscal 2029, and by establishing a resource recovery system before mass production begins, it aims to curb waste problems and support market introduction.
