Quantum-Confined ZnO Nanoshell Photoanodes for Mesoscopic Solar Cells

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

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, Aravind Kumar Chandiran, Mohammad Ibrahim Dar

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 ...

Perovskite Solar Cells with 12.8% Efficiency by Using Conjugated Quinolizino Acridine Based Hole Transporting Material

Michael Graetzel, Mohammad Khaja Nazeeruddin, Norman Pellet, Peng Qin, Mohammad Ibrahim Dar, Sanghyun Paek

A low band gap quinolizino acridine based molecule was designed and synthesized as new hole transporting material for organic-inorganic hybrid lead halide perovskite solar cells. The functionalized quinolizino acridine compound showed an effective hole mob ...
