dc.description.abstractIn this study, CdTe Quantum Dots (QDs) used in QD Sensitized Solar Cell (QDSSC) design were synthesized by Cannula method. Cannula method is a method used to minimize problems occurring in hot injection method, while reducing the Full Width Half Maximum (FWHM) value to 27.20 nm, QD's Photoluminescence Quantum Yield (PLQY) increased to 25.66 +/- 2.1%. This study was carried out to determine the effects of CdTe QDs synthesized by Cannula method on CdTe QDSSC application. Firstly, CdTe QDSSCs with the same parameter values (TiO2 thickness, redox couple, collecting electrode, coating technique and duration) were designed with CdTe QDs synthesized by using classical method and Cannula method. The Photo Conversion Efficiency (PCE) of QDSSCs using CdTe QDs synthesized by Cannula method was 0.234%, 2.68 times bigger than the PCE of the CdTe QDSSC synthesized by the classical method. Then, to determine how the size of CdTe QD affects the PCE of CdTe QDSSCs, 6 CdTe QDSSCs were designed by using different size CdTe QDs which were synthesized by Cannula method. In addition, the FTO/TiO2 surface was treated with TiCl4 in CdTe QDSSCs designed. The decrease in the size of the CdTe QD has been found to increase the PCE of CdTe QDSSC. As a result, the PCE of CdTe QDSSC was increased to 0.385% by using 2.80 nm CdTe QDs synthesized by Cannula method. This PCE is the highest value in CdTe QDSSCs designed using CdTe QDs synthesized in the literature by hot injection method. The current density (J(sc)) and open circuit voltage (V-oc) of the designed CdTe QDSSC were found to be 1.292 mA/cm(2) and 0.724 V, respectively.en_US
