Electrochemıcal Synthesıs Of Indıum Oxıde Nanostructures And Desıgn Of Indıum Oxıde/Cadmıum Sulfıde Quantum Dot Sensıtızed Solar Cells

The exploration for alternative energy sources in order to meet the increasing energy need in the world with the rapidly developing technology has increased the interest especially in solar cells in recent years. This study reports the synthesis of indium oxide (In2O3) based photoanodes decorated with cadmium sulfide (CdS) quantum dots to be used for the first time in the literature in quantum dot sensitized solar cells with high conversion efficiency. The X-ray photoelectron spectroscopy, X-ray powder diffraction spectroscopy, Energy dispersive X-ray spectroscopy, Scanning electron microscopy and photocurrent density measurements were used for the structural, morphological and photoelectrochemical characterization of the synthesized material. Quantum dot sensitized solar cells were designed using the characterized photoanodes and the basic quality parameters, the filling factor, and the conversion efficiency were calculated with the photocurrent densityvoltage curves. As a result of the measurements, it has been determined that the designed solar cells have a filling factor of 0.324 and a conversion efficiency of 0.22%.
