Sun-Believable Solar Paint Could Help Power Your House

Wouldn’t it be grand if you could power your house with a can of paint instead of expensive solar panels? Someday that might be possible. Notre Dame researchers have developed a paste of cadmium sulfide-coated titanium dioxide nanoparticles, or simply referred to as spreadable solar cells.

“By incorporating power-producing nanoparticles, called quantum dots, into a spreadable compound, we’ve made a one-coat solar paint that can be applied to any conductive surface without special equipment,” says Prashant Kamat, John A. Zahm Professor of Science in Chemistry and Biochemistry and an investigator in Notre Dame’s Center for Nano Science and Technology.

According to Science Daily,

Nano-sized particles of titanium dioxide, which were coated with either cadmium sulfide or cadmium selenide. The particles were then suspended in a water-alcohol mixture to create a paste. When the paste was brushed onto a transparent conducting material and exposed to light, it created electricity.

According to Kamat, the new paste’s light-to-energy conversion efficiency is a mere 1 percent, but he hopes his research team will be able to boost that figure closer to 10-15% for commercial use. Kamat believes solar paste technology could truly benefit green living in the future, and appropriately named the paint Sun-Believable.

Would you use solar paint if it became commercially available?
