Not any more
This is actually pretty nifty, if you’re a solar geek. This company, G24i, has been working for a long while to come up with solar cells covered in a dye that, when struck by light, discharges an electron, which is immediately captured by a neighboring crystal of titanium oxide.
It’s unlikely it will scale to industrial applications, but it’s cheap and can be put virtually anywhere, including on small electronic devices (iPods!), even fabrics. The company hopes it will enable renewable devices, moving awareness and engagement with renewable energy into an enormous new mass market.
Like I said, interesting times in the solar world.
