CdS quantum dot sensitized solar cells were fabricated by a solvent modified<br />

successive ionic layer adsorption and reaction (SILAR) method. The use of two<br />

different solvents in the Cadmium precursor solution and the wash step instead<br />

of one unique solvent in the SILAR method enhanced the photovoltaic<br />

parameters of the QDSSC by increasing the light absorption and reducing the<br />

recombination rate of electrons in the device. The reference power conversion<br />

efficiency (PCE) of the device (TiO2/CdS/ZnS) was increased from 2.8% to above<br />

3.23%. A maximum PCE of 3.70% has been obtained by using the solvent<br />

modified approach and optimizing the TiO2 transparent layer thickness.<br />
