Characterization of La-alloyed CdS QDs synthesized by the successive ionic layer adsorption and reaction (SILAR) technique

Abstract

In this present study, the photovoltaic, structural, elemental and optical properties of La-alloyed CdS quantum dots (QDs) synthesized at room temperature using the successive ionic layer adsorption and reaction (SILAR) technique were investigated for the first time. For La-alloyed CdS QDs with different La concentrations, incident photons to current efficiency (IPCE) was measured and the optimum La concentration giving the best solar cell efficiency was determined as 1%. Characterization procedures were then performed to determine the structural and optical properties of La-alloyed CdS QDs with 1% La. As a result, La-alloyed CdS QDs with 1% La have been proposed as promising materials for photovoltaic applications.
