What I found most interesting here, is that there are already '3D cells' with much higher efficiency as commercial ones. These are patented however, so that apparantly only smart kids in schools can do research on further improvement (it's hard to find investors for 'professional' research, when all profits go to someone else). And ofcourse, noone is allowed to put this technique to use, without first paying up.
Luckily, there are things that cannot be patented. How about using light-coloured paints for roads and rooftops in urban areas?

And it's not even a new idea, as you can see in this article, from 1995.

Yes, solar energy is so easy to harvest, that it sometimes requires effort to avoid it :blink:
