Exfoliated 2D Layered and Nonlayered Metal Phosphorous Trichalcogenides Nanosheets as Promising Electrocatalysts for CO2 Reduction

Michael Graetzel, Dan Ren, Hong Zhang, Yelin Hu, Yunfei Jiao, Bing Wu, Chen Shen, Fei Liang

Two-dimensional (2D) materials catalysts provide an atomic-scale view on a fascinating arena for understanding the mechanism of electrocatalytic carbon dioxide reduction (CO2 ECR). Here, we successfully exfoliated both layered and nonlayered ultra-thin met ...

Carbazol-phenyl-phenothiazine-based sensitizers for dye-sensitized solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Felix Thomas Eickemeyer, Lukas Pfeifer, Wei Huang, Dan Ren, Zhongjin Shen, Yunfei Jiao, Yi Ding

Heteroaromatic units are commonly used as pi-spacers for sensitizers in dye-sensitized solar cells (DSSCs). Here, we investigated the influence of the pi-spacer on the photophysical properties, electrochemical properties and photovoltaic performance of car ...

First Principles Design of Dye Molecules with Ullazine Donor for Dye Sensitized Solar Cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Sheng Meng, Yunfei Jiao, Wanli Ma

We design a series of metal-free donor-pi-bridge molecules (denoted VB0-VB4) based on a new donor group-ullazine donor-as sensitizers for dye sensitized solar cell (DSSC) applications. Density functional theory (DFT) and time-dependent DFT calculations rev ...

Structure-Property Relations in All-Organic Dye-Sensitized Solar Cells

Michael Graetzel, Sheng Meng, Fan Zhang, Yunfei Jiao

A structureproperty relationship in all-organic dye solar cells is revealed by first-principles molecular dynamics and real-time time-dependent density functional theory simulations, accompanied with experimental confirmation. An important structural featu ...
