An Indian scientist is developing a more cost-effective method of capturing cheap energy from solar power.
Dilip Joshi, superintendent engineer at the Gujarat Energy Transmission Corporation (Getco), has been devising a way to reduce the manufacturing costs of solar equipment by using less expensive materials such as film, reports the Times of India.
Mr Joshi presented two papers at the Photovoltaic World Conference organised by Renewable Energy World Council in the US earlier this year, outlining his findings.
"I had suggested using a thin film, which is cheaper than the currently-used silicon, for trapping solar energy and storing it in large quantities," he told the Times.
"The film will work even in diffused sunlight and it gets solar energy through heat instead of light."
Mr Joshi's work has attracted attention from international investors, who have shown interest in setting up solar energy plants in the western Indian state of Gujarat.
Meanwhile, researchers at the Massachusetts Institute of Technology recently became the first scientists to print solar cells on paper.
