Quantum dot sensitized solar cell design with surface passivized CdSeTe QDs
Solar Energy, 2020 Abstract One of the main factors affecting the performance of quantum dot sensitized solar cells (QDSSCs) is charge recombination caused by surface traps. It is important to passivize the surface traps of the synthesized QDs as much as possible in order to raise the power conversation efficiency (PCE).
