Abstract

We report for the first time a successful fabrication and operation of an InAs/GaAs quantum dot based
intermediate band solar cell concentrator photovoltaic (QD-IBSC-CPV) module to the IEC62108 standard
with recorded power conversion efficiency of 15.3%. Combining the measured experimental results at
Underwriters Laboratory (ULH) licensed testing laboratory with theoretical simulations, we confirmed that
the operational characteristics of the QD-IBSC-CPV module are a consequence of the carrier dynamics via
the intermediate-band at room temperature.
