Abstract

Various CdS quantum dots (QDs) have been synthesized on the TiO2 nano porous by chemical bath deposition method with times different immersing. The size and morphology of CdS QDs can be observed from scan electron microscope and transmission electron microscopy images. Based on UV- Vis absorption measurement and photocurrent density-voltage characterization, the results display that compared with the device with the uniform size particles, the device with various size CdS QDs shows the better performance with higher short-circuit current density, open-circuit voltage, and power conversion efficiency.

Key Words   
CdS QDs, solar cells
