Semi-transparent solar cells that could be added to windows to efficiently harvest energy from indoor light as well as the sun have been developed by an international team led by UCL researchers.
I wonder why solar window shutters aren’t a thing.
Because the source of light is mostly up in the sky, and solar panels work best when they are mostly perpendicular to the direction the light is shining.
Soooooo how about: shutters
Already addressed.
IMO solution is a ‘european tilt and turn’ window system with an inner window (tint or shade optional) and a solar panel shutter.
With drive motors and suntrackers for the luxury version.
