Mechanism of carrier accumulation in perovskite thin-absorber solar cells
Nature Publishing Group (2013)Photovoltaic conversion requires two successive steps: accumulation of a photogenerated charge and charge separation. Determination of how and where charge accumulation is attained and how this accumulation can be identified ... -
Selective contacts drive charge extraction in quantum dot solids via asymmetry in carrier transfer kinetics
Nature Publishing Group (2013)Colloidal quantum dot solar cells achieve spectrally selective optical absorption in a thin layer of solution-processed, size-effect tuned, nanoparticles. The best devices built to date have relied heavily on drift-based ...
