Inexpensive Solar Cell Paint One Step Closer After "Major Advance" in Research


Not the actual paint...

TreeHugger has covered paint-on or spray-on solar cells on a number of occasions. The idea isn't new by any means. But some researchers from the University of Notre Dame say they have made a "major advance" towards making an inexpensive solar paint. They've called it (be prepared to groan) Sun-Believable.

Lead researcher Prashant Kamat:

By incorporating power-producing nanoparticles, called quantum dots, into a spreadable compound, we've made a one-coast solar paint that can be applied to any conductive surface without special equipment.
The best light-to-energy conversion efficiency we've reached so far is 1%, which is well below the usual 10-15% efficiency of commercial silicon solar cells. But this paint can be made cheaply and in large quantities. If we can improve the efficiency somewhat, we may be able to make a real difference in meeting energy needs in the future.

The efficiency is still far below what's needed to make this competitive with traditional solar products, but painting on solar cells remains an appealing dream.
