The Indian Scientists are once again in the news.
New research led by an Indian origin professor in the US heralds the day when one can apply a coat of paint on the outside walls of a house to generate electricity from sunlight that can be used to power the appliances and equipment on the inside.
The inexpensive "solar paint" uses semiconducting nanoparticles of titanium dioxide coated with either cadmium sulfide or cadmium selenide to produce energy.

The inexpensive "solar paint" uses semiconducting nanoparticles of titanium dioxide coated with either cadmium sulfide or cadmium selenide to produce energy.
The research led by chemistry professor Prashant Kamat in Notre Dame's Center for Nano Science and Technology is christened as "Sun-Believable Solar Paint".
By incorporating power-producing nanoparticles, called quantum dots, into a spreadable compound, they have made a one-coat solar paint that can be applied to any conductive surface without special equipment."
The paste of nanoparticles when applied on surfaces using simple conventional paint brush "could turn large surfaces into solar cells"
While the resulting output was far lower than conventional silicon methods, Prof Kamat is already working on further refining it.
Imagine the day when all surfaces become solar batteries to power homes, cars etc.
