Li, Mingjie; Saikat Bhaumik; Teck Wee Goh; Muduli Subas Kumar; Natalia Yantara; Michael Gra¨tzel; Subodh Mhaisalkar; Nripan Mathews; Sum, Tze Chien, 2019, "Replication Data for: Slow cooling and highly efficient extraction of hot carriers in colloidal perovskite nanocrystals", https://doi.org/10.21979/N9/U8RXH5, DR-NTU (Data), V1
Hot-carrier solar cells can overcome the Shockley–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 pathways (for example, in... |
