Multibandgap quantum dot ensembles for solar-matched infrared energy harvesting

Efficient harvest of solar energy beyond the silicon absorption edge of 1100 nm by semiconductor solar cells remains a challenge. Here Sun et al. mix high multi-bandgap lead sulfide colloidal quantum dot ensembles to further increase both short circuit current and open circuit voltage.
