Synergistic Doping of Fullerene Electron Transport Layer and Colloidal Quantum Dot Solids Enhances Solar Cell Performance
IMO, QMC Solterra QDSC will use tetrapod QD which already have excellent electron transport due to shape. The problem with adding a layer of fullerene is that it is another layer of complication. Ideal construction would be one pass of the inkjet or surface deposition printing and then seal the cell.
