Abstract
Heterojunction solar cells based on PbS quantum dots (QDs) were prepared at room temperature via spin coating method. The PbS QDs were synthesized, characterized and utilized in p-n heterojunction solar cell structure. The effect of combining two different n-type nanoparticles on the solar cell photovoltaic performance was studied. The solar cells were characterized under 1 sun illumination (irradiation of 1,000 W/m2). The optimum solar cell by depositing PbS QDs layer onto ZnO/CdS nanoparticles layers exhibits a short-circuit current of 1.36 mA/cm2, open circuit voltage of 127 mV, and power conversion efficiency of 1.21 %, representing efficiency improvement more than 3 and 5 orders of magnitude compared with the case of employing only one n-type nanoparticles ZnO and CdS, respectively.
