The solar energy is one of the potential renewable green energy source considering the availability of sunlight in abundance and the need for clean and renewable source of energy. Quantum dots are semiconductor nanocrystals having considerable interest in photovoltaic research areas. Cadmium sulfide-sensitized solar cells are synthesized by Chemical bath deposition and titanium nanowires were fabricated by hydrothermal method. The synthesized CdS quantum dots are sensitized to nanoporous TiO2 films to form quantum dots-sensitized solar cell applications. The introduction of TNWs enables the electrolyte to penetrate easily inside the film which increases the interfacial contact between the nanowires, the quantum dots and the electrolyte results in improvement in efficiency of solar cell. The goal of our research is to understand the fundamental physics and performance of quantum dot-sensitized solar cells with improved photoconversion efficiency at the low cost based on selection of TiO2 nanostructures, sensitizers and electrodes through an integrated experimental and modeling study.

Highly Uniform

Tricolor microbeads for biological assay have been prepared by embedding three quantum dots (cadmium selenide semiconductor nanocrystals) of different size into carboxyl-functionalized polystyrene (PS-COOH) microbeads. These efforts can render CdSe nanocrystals water-solubility, chemical stability and good photostability. The results indicate that QDs-tagged microbeads are highly uniform, reproducible and strong in fluorescence emission. Based on the properties it possesses, QDs-tagged microbead may have great potential for bio-detection.
