New Technology Offers Spray-On Solar Power



Scientists of University of Toronto faculty of applied science and engineering have just invented a new way to spray solar cells onto flexible surfaces using miniscule light sensitive meterials known as colloidal quantum dots a major step forward making spray on solar cell easy and cheap to manufacture.
                Solar sensitive colloidal quantum dots printed on to a flexible film could be used to coat all kinds of surfaces from patio furniture to aeroplane wings .A surface ,the size of  your cars roof wrapped with colloidal quantum dots coated film would produce enough energy to power three 100 watts bulb
