Branched and bulky substituted ruthenium sensitizers for dye-sensitized solar cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Aravind Kumar Chandiran

We report on the synthesis, and photovoltaic performances of four novel Ru(II)-bipyridine heteroteptic complexes TT206-209, incorporating branched and bulkier alkyl chains compared to their linear analogues C106 and CYC-B11 previously reported. In both ser ...

The Application of Electrospun Titania Nanofibers in Dye-sensitized Solar Cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Ladislav Kavan, Aravind Kumar Chandiran

Titania nanofibers were fabricated using the industrial Nanospider (TM) technology. The preparative protocol was optimized by screening various precursor materials to get pure anatase nanofibers. Composite films were prepared by mixing a commercial paste o ...

Pyridyl- and Picolinic Acid Substituted Zinc(II) Phthalocyanines for Dye-Sensitized Solar Cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Jun Ho Yum, Aravind Kumar Chandiran

A series of tri-tert-butyl zinc(II) phthalocyanines (Pcs) substituted with pyridyl, carboxyl, or picolinic acid anchoring groups on the periphery were prepared. Photovoltaic (PV) studies on these dyes were carried out revealing some interesting features. I ...

Sub-nanometer Ga2O3 tunnelling layer by atomic layer deposition to achieve 1.1V open-circuit potential in dye-sensitized solar cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Robin Humphry-Baker, Chenyi Yi, Aravind Kumar Chandiran, Nicolas Tétreault

Herein, we present the first use of a gallium oxide tunnelling layer to significantly reduce electron recombination in dye-sensitized solar cells (DSC). The sub-nanometer coating is achieved using atomic layer deposition (ALD) and leading to a new DSC reco ...

Quantum-Confined ZnO Nanoshell Photoanodes for Mesoscopic Solar Cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Mohammad Ibrahim Dar, Chenyi Yi, Aswani Yella, Aravind Kumar Chandiran, Mojtaba Abdi Jalebi

We present a photoanode for dye-sensitized solar cell (DSC) based on ZnO nanoshell deposited by atomic layer deposition at 150°C, on a mesoporous insulating template. An ultrathin layer of ZnO between 3 and 6 nm, which exhibits quantum confinement effect, ...

Controlled synthesis of TiO2 nanoparticles and nanospheres using a microwave assisted approach for their application in dye-sensitized solar cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Mohammad Ibrahim Dar, Aravind Kumar Chandiran

Rapid and facile synthesis of similar to 7 nm and similar to 100-400 nm nano-structures of anatase titania is achieved by exploiting the chemical nature of solvents through a microwave based approach. After using these nanostructures as a photoanode in dye ...

Doping a TiO2 Photoanode with Nb5+ to Enhance Transparency and Charge Collection Efficiency in Dye-Sensitized Solar Cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Pascal Comte, Aravind Kumar Chandiran

The optoelectronic properties of our benchmark nanocrystalline anatase TiO2 photoanode were modified by means of aliovalent doping with Nb5+. Even for a low doping level, the charge collection efficiency can be noticeably improved as a result of a higher e ...
