Slow cooling and highly efficient extraction of hot carriers in colloidal perovskite nanocrystals

Michael Graetzel, Nripan Mathews, Mingjie Li

Hot-carrier solar cells can overcome the Schottky-Queisser limit by harvesting excess energy from hot carriers. Inorganic semiconductor nanocrystals are considered prime candidates. However, hot-carrier harvesting is compromised by competitive relaxation p ...

Low threshold and efficient multiple exciton generation in halide perovskite nanocrystals

Michael Graetzel, Nripan Mathews, Qiang Xu, Mingjie Li

Multiple exciton generation (MEG) or carrier multiplication, a process that spawns two or more electron-hole pairs from an absorbed high-energy photon (larger than two times bandgap energy E-g, is a promising way to augment the photocurrent and overcome th ...
