Soft Color Composites with Tunable Optical Transmittance

Pedro Miguel Nunes Pereira de Almeida Reis

A class of soft color composites whose light transmittance can be actively tuned and controlled through mechanical actuation is studied. The design comprises thin sheets of polydimethylsiloxane, an optically clear silicone-based rubber, that is mixed with ...

Improving charge collection with delafossite photocathodes: a host–guest CuAlO2/CuFeO2 approach

Kevin Sivula, Nestor Guijarro Carratala, Yang Li, Mathieu Steven Prévot

p-Type delafossite CuFeO2 has recently been reported as a promising candidate for direct photoelectrochemical solar water reduction in alkaline conditions. However, despite its favorable optical band gap energy and light absorption, this material suffers f ...

High Absorption Coefficient Cyclopentadithiophene Donor-Free Dyes for Liquid and Solid-State Dye-Sensitized Solar Cells

Shaik Mohammed Zakeeruddin, Antonio Abate, Yelin Hu, Yiming Cao

We report a series of "donor-free" dyes featuring moieties of oligo(4,4-dihexyl-4H-cyclopenta[1,2-b:5,4-b']dithiophene) (CPDT) functionalized with cyanoacrylic end groups for mesoscopic titania solar cells based on I-/I-3(-) or Co(II)/Co(III) redox couple ...

Molecular Engineering of Potent Sensitizers for Very Efficient Light Harvesting in Thin-Film Solid-State Dye-Sensitized Solar Cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Fabrizio Giordano, Chenyi Yi, Norman Pellet, Yelin Hu, Marcel Roland Schreier, Xiaoyu Zhang, Yi Xu

Dye-sensitized solar cells (DSSCs) have shown significant potential for indoor arid building integrated photovoltaic applications. Herein we present three new D-A-pi-A organic sensitizers, XY1, XY2, and XY3, that exhibit high molar extinction coefficients ...

It is known that excitation by visible light of the singlet metal-to-ligand charge-transfer (1MLCT) states of Fe(II) complexes leads to population of the lowest-lying high-spin quintet state (T-5) with unity quantum yield. Here we investigate this so-calle ...
