Chemical engineering Professor Brian Korgel tests one of his printed solar cells
At the core of Korgel’s research are the sunlight-absorbing nanoparticle 'inks'
Turning rooftops into solar cells ... researchers apply the nanoparticle 'inks'
Cheaper solar cells – roughly one-tenth the cost of current day prices – could be available within three to five years thanks to a manufacturing procedure that uses nanoparticle ‘inks’ to print them like newspaper or to spray-paint them onto the sides of buildings or rooftops. Even windows could become solar cells thanks to the semi-transparent inks. 'Painting' solar cells on buildings has been an idea in the making for some time – Gizmag investigated the possibilities of 'solar paint' in 2008.
