"This solar "paint" would have the same function as the large photovoltaic (PV) solar collectors on buildings and "solar farms" around the world.
Korgel describes the tiny collection devices as a "solar sandwich."
"So these devices are 'sandwiches,' where you have the metal contact on the bottom and metal contact on the top to extract the charge out; and the middle part is the part that absorbs out the light," explains Korgel.
This paint, made of the CIGS nanocrystals, can be sprayed on plastic, glass and even fabric to create a solar cell."
The work being done on research & development of renewable energy is amazing.
