Mercury Telluride Quantum Dots for Infrared Luminescent Solar Concentrators

摘要

Newly developed mercury telluride (HgTe) quantum dots (QDs) with peak emission in the infrared (IR) region (～1500nm) have been characterised using absorption and photoluminescence spectroscopy. The QDs have been encapsulated into poly(methylmethacrylate) (PMMA) and the effect of curing temperature has been investigated. It was found that temperatures above 40℃ have a detrimental effect on the emission intensity the QDs.rnRay-trace simulations were carried out for LSCs containing HgTe QDs using measured data for germanium (Ge) solar cells. Results show that host absorption in bulk samples reduces predicted module efficiency and that thin films are more suitable for the QDs investigated in this study.
