Colloidal quantum dot solar cell breakthrough - Electronics News

Latest from News LEDs to light the Louvre Nitride semiconductor key to artificial photosynthesis DRAM oversupply a vicious circle: GBI Expert Cheaper semiconductor packaging material Autonomous robots to fight it out RESEARCHERS from the University of Toronto and King Abdullah University of Science & Technology have made a breakthrough in the development of colloidal quantum dot (CQD) films. This breakthrough has led to the most efficient low-cost CQD solar cell ever, with a 7.0 percent efficiency, representing a 37 percent increase on efficiency over the previous certified record. Previously, quantum dot solar cells have been limited by the large internal surface areas of the nanoparticles in the film, which made extracting electricity difficult. The researchers used a combination of organic and inorganic chemistry to completely cover all of the exposed surfaces. Quantum ...
