3M shows photovoltaic film for windows
-- 3M drew press and viewer interest earlier this week at CEATEC with its show of special film that the company has developed to coat ordinary, existing windows and convert them into solar panels. The product was shown on curved and regular glass surfaces. This “windows-transformative” film is to debut next year. Not only does the panel generate energy in sunlight, but it also serves as a heat-blocking layer.
