Special Issue Information
Colloidal semiconductor nanostructures are outstanding materials with optical and electronic properties which are tunable via size and dimensionality due to quantum confinement effects. Further, heterostructures combining domains of different semiconductor materials within one particle offer additional adjustability with respect to spatial confinement or delocalization and separation of charge carriers. These properties can be exploited to tailor structures for optimal harvesting of light in a large part of the visible spectrum and for support of efficient separation of charges, which is the fundament for the application of these materials for light harvesting. The scope of this Special Issue is to cover the recent progress and advances in the research on designing colloidal semiconductor nanostructures and their application for light harvesting, e.g., in assemblies for light-driven catalysis or in photovoltaic devices. Reports on synthesis, characterization, device integration, and application will be collected in this issue. Further, insight from spectroscopic investigations on charge-carrier dynamics and computational studies are highly welcome. Potential topics include but are not limited to:
- Synthesis of colloidal nanostructures and functionalization with cocatalysts;
- Generation of nanoparticle/polymer hybrid materials;
- Self-assembly and deposition of layered structures;
- Theoretical studies and modeling;
- Spectroscopic characterization;
- Electrochemical characterization;
- Charge-carrier dynamics;
- Multiple exciton generation;
- Plasmonic effects;
- Device integration.
It is my pleasure to invite you to submit communications, full papers or reviews to this Special Issue.

Title: Optically Controlled Supercapacitors: The Effect of Colloidal Semiconductor and Additives

Abstract: Optically manipulated supercapacitors (S-C) may be of interest to the sensor community and could set the stage for optically controlled charging elements. The structures are constructed of two parallel, transparent and conductive electrodes (indium-tin-oxide, ITO). An active carbon (A-C) layer, which is embedded with semiconductor particles, such as TiO2 is then deposited on the ITO electrodes. As previously shown, the optically induced capacitance change is large [1,2] and is attributed to polarization and thermal effects. In order to further understand the role of the colloid size and its spectral response, a study is conducted on sub-micron and micron size TiO2 particles. Phase change material - 15 micron VO2 powder - is added to the A-C layer in an attempt to study the effect of increased conductivity under elevated temperatures. The results of 2- and 3-electrode experiments will be presented.
