Solar paint is inefficient but simple to make
January 4, 2012
Notre Dame researchers have developed a simple, cheap alternative to traditional solar cells: solar paint, IEEE Spectrum Energywise reports.
The paint, made with semiconducting nanoparticles, achieved a one percent conversion rate when tested using artificial sunlight. This is far behind other solar technologies — which fall in the 10 to 15 percent range, generally — but the ease of manufacturing and use are clear advantages.
