Panasonic advances glass-type perovskite solar cell mass production to April 2029
Panasonic has brought forward planned mass production of glass-type perovskite solar cells from fiscal 2030 to April 2029. It has begun selling initial production models made at its research and development base in Moriguchi, Osaka, preparing for full-scale production in Nagahama, Shiga. The company says these products can use windows and walls as power-generating sites.

What to know
