MIT Researchers Invent Solar Cells That Transform Heat Into Electricity

If you thought photovoltaics can only get energy from the Sun, then you were wrong. An MIT team of researchers have invented a device that produces electricity from heat. The process uses the photovoltaic effect as the middleman and is three times more efficient than the most efficient lithium ion batteries on market today.

New Colloidal Quantum Dots Solar Cells Gather Visible and Infrared Light

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.
