Time-Resolved Photocurrent Measurements on PbS Nanocrystal Schottky-Contact Photovoltaic Cells

Abstract:

Article Preview

We fabricated and characterized NIR-active Schottky-contact solar cells with PbS nanocrystals (NCs) as the active medium. The photovoltaic e ffect is due to carrier generation in the PbS NCs as proven by the comparison of the spectrally-resolved external quantum effciency of the devices and absorbance spectra of the PbS NCs. The operative regime is extended well beyond the Si bandgap into the infrared spectral region up to 1500 nm limited by our measurement setup. One sun I-V and time-resolved photocurrent measurements help to identify critical solar cell parameters for the further improvement of PbS NC Schottky-contact solar cells.
