Abstract
Semiconductor quantum-dot-sensitized TiO2 thin-film solar cells have been assembled by incorporating CdS quantum dots into the TiO2 porous film. The influence of acid treatment on TiO2 electrode, dipping time, and the effect of electrolytes on the performance of solar cells have been investigated. Two types of solar cells have been fabricated, one using a liquid electrolyte and the other one using a quasi-solid-state polymer electrolyte. It has been found that quantum-dot-sensitized solar cells exhibits better photovoltaic performance when the TiO2 electrode was acid-treated. When the TiO2 electrode was acid-treated, the short-circuit current, open-circuit voltage, fill factor, efficiency, and even the amount of quantum dots absorbed by the TiO2 film was found to increase appreciably. The quantum dot solar cells fabricated using liquid electrolyte were observed to exhibit better efficiency than the quasi-solid-state polymerelectrolyte- based solar cells.
