First-Principles Modeling of Optically Active Organic Molecules in Solar Cell Devices and Biological Environments

Jun Ren

With the increasing cognition of the importance of organic molecules, they are widely applied in printing, biological and pharmacological fields, because of their special capabilities of harvesting solar light, scavenging free radicals, and chelating metal ...

Energy and Hole Transfer between Dyes Attached to Titania in Cosensitized Dye-Sensitized Solar Cells

Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Robin Humphry-Baker, Peng Wang, Thomas Moehl

Cosensitization of broadly absorbing ruthenium metal complex dyes with highly absorptive near-infrared (NIR) organic dyes is a clear pathway to increase near-infrared light harvesting in liquid- based dye-sensitized solar cells (DSCs). In cosensitized DSCs ...

High-voltage (1.8 V) tandem solar cell system using a GaAs/AlXGa(1-X)As graded solar cell and dye-sensitised solar cells with organic dyes having different absorption spectra

Michael Graetzel, Jun Ho Yum, Paul Liska, Péter Kalman Péchy, Pascal Comte

Stacked multijunction (tandem) solar cells have been prepared by mechanically stacking dye-sensitised solar cells (DSCs) and a GaAs/AlXGa(1-X)As graded solar cell (GGC) as the top and bottom cells, respectively. Three organic dyes with different absorption ...

High-throughput nanofabrication of plasmonic structures and metamaterials with high resolution nanostencil lithography

Hatice Altug, Serap Aksu, Min Huang

We demonstrate a novel fabrication approach for high-throughput fabrication of engineered plasmonic antenna arrays and metamaterials with Nanostencil Lithography (NSL). NSL technique, relying on deposition of materials through a shadow mask, offers the fle ...

Comparative study between dye-sensitized and CdS quantum-dots-sensitized TiO2 solar cells using photoinduced absorption spectroscopy

Ulf Anders Hagfeldt

Two 8 μm thick TiO2 photoelectrodes have been sensitized sep. by N719 dye mols. and CdS quantum dots for a comparison study. Photoinduced absorption (PIA) spectroscopy was employed to investigate the mechanistic properties of electrons under illumination c ...

Plasmon induced transparency in cascaded pi-shaped metamaterials

Hatice Altug, Arif Engin Cetin

We experimentally and numerically demonstrate a planar metamaterial consisting of two asymmetrically positioned pi-structures in a single unit that exhibits plasmonic analogue of electromagnetically induced transparency (EIT). Through the coupling of the c ...

Fundamental limits in the external quantum efficiency of single nanowire solar cells

Anna Fontcuberta i Morral, Martin Heiss

The fundamental limits for the measurement of the efficiency of single nanowire solar cell devices are presented. We evaluate the effect of the substrate, light polarization, and existence of Mie resonances in the absorption of the solar spectrum for nanow ...

Incorporating Multiple Energy Relay Dyes in Liquid Dye-Sensitized Solar Cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Shaik Mohammed Zakeeruddin, Jun Ho Yum

Panchromatic response is essential to increase the light-harvesting efficiency in solar conversion systems. Herein we show increased light harvesting from using multiple energy relay dyes inside dye-sensitized solar cells. Additional photoresponse from 400 ...

High external quantum efficiency and fill-factor InGaN/GaN heterojunction solar cells grown by NH3-based molecular beam epitaxy

Elison de Nazareth Matioli

High external quantum efficiency (EQE) p-i-n heterojunction solar cells grown by NH3-based molecular beam epitaxy are presented. EQE values including optical losses are greater than 50% with fill-factors over 72% when illuminated with a 1 sun AM0 spectrum. ...
