When Is A Window Not A Window? When It Makes Solar Energy!

When Is A Window Not A Window? When It Makes Solar Energy!

When is a window just not a window? When it’s a solar energy generator, thanks to solar cells crafted of carbon nanotubes which are so transparent they can be sprayed on window glass and so flexible they can be woven into fabric like window curtains or drapes. Well, that’s not true either, since the solar cell-coated windows still act as windows, according to researcher/inventor Dr. Mark Bissett of Flinders University School of Chemical and Physical Sciences in Adelaide, South Australia. But these windows, besides offering light, fresh air and a view, also provide energy via the photovoltaic process. And, since windows are up to 75 percent of a modern building’s exterior, the amount of potential energy generated is enormous. The process of using solar-energy delivery materials on building surfaces is known as BIPV, for B uilding I ntegrated P hotov oltaics, and promises to...
