Evidence is provided for nonradiative resonant energy transfer (NRET) from excitons in nanocrystal quantum dots (NCQDs) to the confined states of an adjacent quantum well (QW) at low excitation power and rate competitive with the quantum dot radiative decay. This indicates that NRET in optimized NCQD−QW/nanowire systems may provide a solar energy conversion approach with a viable tradeoff with the bottlenecks of charge carrier generation and/or transport to/in electrodes faced by excitonic solar cells.
