Innovative new windows that turn sunlight passing through them into energy have passed real-world testing.

SolarWindow Technologies has announced its transparent electricity-generating glass has survived the autoclave lamination process, which uses high heat and pressure to bond layers of glass together, as required for safety and architectural reasons.

Subsequent performance testing confirmed the photovoltaic modules continued to produce power. Its developers say the solar glass could mean tall towers and skyscrapers become clean power generators.

John Conklin, President and CEO of SolarWindow Technologies, said:”We’ve long championed the prospect of electricity-generating windows powering skyscrapers and tall towers, which alone consume almost 40% of all the electricity generated in the US.”

A single installation on a 50-storey building could reportedly halve electricity costs and cut annual carbon dioxide emissions by the equivalent of a car travelling two million miles.
