In situ investigation of the early stage of TiO2 epitaxy on (001) SrTiO3

We report on a systematic study of the growth of epitaxial TiO2 films deposited by pulsed laser deposition on Ti-terminated SrTiO3 (001) single crystals. By using in situ reflection high energy electron diffraction, low energy electron diffraction, x-ray p ...

Application of Cu(II) and Zn(II) coproporphyrins as sensitizers for thin film dye sensitized solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Mingkui Wang, Pascal Comte, Joël Teuscher, Davide Di Censo, Leila Alibabaei

We synthesized the Cu(II) and Zn(II) complexes of the 2,7,12,17-tetrapropionic acid of 3,8,13,18-tetramethyl-21H,23H porphyrin (coproporphyrin-I) and successfully employed them as sensitizers in dye-sensitized solar cells. Copper(II) coproporphyrin-I exhib ...

The Influence of Local Electric Fields on Photoinduced Absorption in Dye-Sensitized Solar Cells

Ulf Anders Hagfeldt

The dye-sensitized solar cell (DSC) challenges conventional photovoltaics with its potential for low-cost prodn. and its flexibility in terms of color and design. Transient absorption spectroscopy is widely used to unravel the working mechanism of DSCs. A ...

Molecular design of metal-free D–π-A substituted sensitizers for dye-sensitized solar cells

Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Mingkui Wang, Robin Humphry-Baker, Joël Teuscher, Davide Di Censo, Nuttapol Pootrakulchote, Yuxiang Yu, Leila Alibabaei

Novel donor-p-acceptor (D--A) dyes, coded as SD-1, SD-2 and SD-5, were designed and synthesized for dye-sensitized solar cells. All these dyes comprised the same donor and acceptor units while the oligo thiophene units were introduced as linkers between th ...

Efficient organic dye-sensitized solar cells based on an iodine-free electrolyte

Xiaoqing Jiang, Ulf Anders Hagfeldt

An org. redox couple (McMT-/BMT) was used in dye-sensitized solar cells. Based on a low-cost org. dye, TH305, an efficiency of 4.0% was achieved under simulated sunlight (100 mW/cm2). Photoelectrochem. measurements provided insight into the difference betw ...
