Description
Summary:The effect of the gold nanoparticles on the quantum dots sensitized solar cells has been investigated. Gold nanoparticles were added in quantum dot CdSe before used as a sensitizer. The result showed that addition of colloidal gold nanoparticles could be enhanced the absorbance of quantum dot CdSe sensitizer. In this research, the QDSCs were arranged in the sandwich structure consecutively TiO2 as photoelectrode, gold nanoparticle, and quantum dot CdSe as a sensitizer, KI as electrolyte and black carbon as counter-electrode. The use of gold nanoparticles and quantum dot improved the average efficiency of the QDSC by about 104%.
