A company named Octillion announced in a press release yesterday their development plan to use “nanosilicon photovoltaic solar cells that have the potential to convert normal home and office glass windows into ones capable of converting solar energy into electricity.”
“When thin films of silicon nanoparticles are deposited (sprayed) onto silicon substrates, ultraviolet light is absorbed and converted into electrical current. With appropriate connections, the film acts as nanosilicon photovoltaic solar cells that has the potential of converting solar radiation to electrical energy.”
