Abstract

Lead sulfide quantum dots represent an emerging photovoltaic absorber material. While their associated optical qualities are true for the colloidal solution phase, they change upon processing into thin-films. A detailed view to the optical key-parameters during solid-film development is presented and the limits and outlooks for this versatile and promising absorber are discussed.

Keywords: atomic ligands; lead sulfide quantum dots; quantum dot photovoltaic cells; spectroscopic ellipsometry; time-resolved photoluminescence.
