A solar cell developed at the Unversity of Toronto, Canada, is able to harvest both visible and infrared light and can theoretically achieve efficiencies of up to 42 percent. Their tandem solar cell is based on colloidal quantum dots (CQD), and the team has been led by Professor Ted Sargent, a Professor of Electrical and Computer Engineering.

Cost-efficient and energy-efficient solar cells could be right around the corner. These so-called "third-generation" photovoltaics begin to emerge nowadays and dismiss a theory stated in 1961 by William Shockley and Hans Queisser, who showed that there is a theoretical 31 percent limitation in what regards the maximum efficiency for a single solar cell.
