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.
“This is the front-runner of low-cost solar cell technologies,” said Hiroshi Segawa, a professor at the University […]
Getting closer to turning the corner…lets hope this happens sooner than later because the entire world needs to move forward with cheap flexible clean energy. silicon has not delivered.
