Abstract
Colloidal Quantum Dots (CQDs) are the route for low cost high eficiency
photodetectors. Photoconductors are limited by the noise arising from high dark current
densities, what is typically overcome reducing device's active area. However, this technique also
reduces their photoresponse, and their optical absorption must be maintained as the volume
is reduced. We study the use of plasmonics for that purpose, and present simulation results
for solution-processed structures compatible with these techniques, showing up to a 13-fold
enhancement in absorption. We present experimental results of a PbS CQDs photoconductor,
fabricated using a novel CQDs functionalization, and venture the potential of these devices
complemented with the shown promising techniques.
