Optical and Photovoltaic Properties of CdS/Ag₂S Quantum Dots Co-Sensitized-Solar Cells

Abstract:

_{Subscript text}We present a co-sensitization of CdS/Ag₂S quantum-dot as sensitizers for solar cells. The optical properties of single and double-layered quantum-dot conditions were monitored using UV-Vis spectrophotometer. The results show that the different characteristics of absorption spectra depended on the types of QDs, indicating to the different energy gap of each QDs deposited on TiO₂ surface and the tunable absorption ranges of the sample of double-layered quantum-dot-sensitized TiO₂ electrodes are broader and the absorption intensity are higher than the single-layered quantum-dot, attributed to the co-absorption of two QDs to the light and both CdS and Ag₂S are activated in visible to near-infrared region (450-1100 nm). The photovoltaic data shows that the highest efficiency of 1.41% with a photocurrent density, J_sc of 20.6 mA/cm², an open-circuit voltage, V_oc of 0.32 V and a fill factor, FF of 21.3% were yielded by the sample of CdS(3)/Ag₂S(4) as an optimum condition of dipping cycles for CdS and Ag₂S under irradiance of 100 mW/cm² (AM 1.5G).
