Spray-On Solar Cells

Researchers Think They're Getting Closer to Making Spray-On Solar Cells a Reality

Once the conversion efficiency of perovskite, a synthesized crystal, rose above 10 percent for the first time, thousands of researchers from other projects switched over to work on these cells accelerating development and producing results over 20 percent.  This compared to the efficiency rate of silicon cells, which has been stuck at approximately 25% for 15 years.  

From the Bloomberg article:

Imagine a future when solar cells can be sprayed or printed onto the windows of skyscrapers or atop sports utility vehicles -- and at prices potentially far cheaper than today’s silicon-based panels.

It’s not as far-fetched it seems. Solar researchers and company executives think there’s a good chance the economics of the $42 billion industry will soon be disrupted by something called perovskites, a range of materials that can be used to harvest light when turned into a crystalline structure.

The hope is that perovskites, which can be mixed into liquid solutions and deposited on a range of surfaces, could play a crucial role in the expansion of solar energy applications with cells as efficient as those currently made with silicon. One British company aims to have a thin-film perovskite solar cell commercially available by the end of 2018.
