These solar glass blocks would make great skylights for your solar roof

If you’re going to be decking your roof out with solar tiles, there’s a possibility that you may forgo what might be the best placement of a skylight in favor of more solar cell square footage. Luckily solar glass is fast becoming an option, and these clever glass blocks are the best option I’ve seen yet.

Other solar glass options generally harvest in the infrared range, since if you captured the full spectrum — well, that wouldn’t be a window, it’d be a wall. But the energy you can capture is limited.

Researchers at the University of Exeter thought up an interesting alternative that may be the best of both worlds (until the next breakthrough, anyway). They created these thick blocks of glass with optical features — not quite lenses or tunnels, but sort of light…
