Journal ArticleDOI

Recombination in Quantum Dot Sensitized Solar Cells

TL;DR: The strategies for depositing CdSe quantum dots on nanostructured mesoporous TiO(2) electrodes are summarized and the methods that facilitate improvement in the performance and stability of QDSCs are discussed.
Journal ArticleDOI

Improving the performance of colloidal quantum-dot-sensitized solar cells.

TL;DR: Several factors cooperate to improve the performance of quantum-dot-sensitized solar cells: an open structure of the wide bandgap electron collector, which facilitates a higher covering of the internal surface with the sensitizer, a surface passivation of TiO2 to reduce recombination and improved counter electrode materials.
Journal ArticleDOI

CdSe Quantum Dot-Sensitized TiO2 Electrodes: Effect of Quantum Dot Coverage and Mode of Attachment

TL;DR: In this paper, the authors investigated the sensitization of nanoporous titanium dioxide by previously synthesized CdSe quantum dots (QDs) protected with trioctylphosphine.
Journal ArticleDOI

Factors determining the photovoltaic performance of a CdSe quantum dot sensitized solar cell: the role of the linker molecule and of the counter electrode.

TL;DR: The linker molecule plays a determinant role in the solar cell performance, as illustrated by the fact that the incident photon to charge carrier generation efficiency (IPCE) could be improved by a factor of 5-6 by using cysteine with respect to MPA.
Journal ArticleDOI

The Electrochemistry of Nanostructured Titanium Dioxide Electrodes

TL;DR: The main conceptual tools needed to address the study of the electrochemical properties of TiO(2) nanostructured electrodes are reviewed, as well as the electrochemistry methods to prepare and modify them.
