The best materials for carrier multiplication in solar cells

Researchers in the Netherlands have sought to identify all those semiconductor materials that may make the application of carrier multiplication in photovoltaics much more than a mere suggestion. According to them, the bandgap of the materials should be between 0.6-1.0 electronvolt (eV), which would result in maximum theoretical efficiency of around 44%. 2D and bulk materials were indicated as the most promising with near-ideal carrier multiplication.New research from the Delft University of Technology (TU Delft) and the University of Amsterdam in the Netherlands has described all the new advances ...
