Plasmon induced transparency in cascaded pi-shaped structures

Hatice Altug, Arif Engin Cetin

We demonstrate a composite metamaterial composed of two asymmetrically oriented pi-shaped structures that exhibits plasmonic analogue of electromagnetically induced transparency (EIT). The structure exhibits fine tuning of EIT-like spectral behavior and sp ...

A selective co-sensitization approach to increase photon conversion efficiency and electron lifetime in dye-sensitized solar cells

Michael Graetzel, Kazuteru Nonomura

Ruthenium-based C106 and organic D131 sensitizers have been judicially chosen for co-sensitization due to their complementary absorption properties and different molecular sizes. Co-sensitization yields a higher light-harvesting efficiency as well as bette ...

Role of the Triiodide/Iodide Redox Couple in Dye Regeneration in p-Type Dye-Sensitized Solar Cells

Ulf Anders Hagfeldt, Yann Pellegrin

A series of perylene dyes with different optical and electronic properties have been used as photosensitizers in NiO-based p-type dye-sensitized solar cells. A key target is to develop dyes that absorb light in the red to near-IR region of the solar spectr ...

Measurement of the Open-Circuit Voltage of Individual Subcells in a Dual-Junction Solar Cell

Christophe Ballif, Matthieu Despeisse, Grégory Bugnon, Jakub Holovsky, Peter Cuony, Maximilien Joseph Marie Bonnet-Eymard

Dual-junction solar cells have the potential for higher conversion efficiencies than single junctions, thanks to a better utilization of the solar spectrum. However, their optimization is more complex because the monolithic interconnection makes the indivi ...
