Self-Assembly of Squaraine Dyes: A Thermodynamic Exploration of Aggregation on Device Properties

Spencer S., Murcia V., Heaphy P., Bougher C., Conrad B., Misture S., Cody J., Collison C., Rochester Institute of Technology, US

Using a comprehensive experimental and theoretical approach, we present a set of materials from the squaraine family that can serve as a unique energetic probe of the bulk heterojunction. We demonstrate successful devices and tight [...]

Statistical Analysis of Electroplated Indium (III) Sulfide (In2S3) Films, a Potential Buffer Material for PV (Heterojucntion Solar Cells) Systems, using Organic Electrolytes

Ali Mughal M., Newell M.J., Vangilder J., Thapa S., Hall J., McNew D., Felizco F., Wood K., Engelken R., Carroll B.R., Johnson J.B., Arkansas State University, US

Deposition conditions were optimized in order to avoid non-uniformity, cracks, and improper stoichiometry in electrodeposited indium (III) sulfide (In2S3)thin films using statistical analysis.

A New Class of Nonlinear Light Trapping for Photovoltaic Systems

Shepard S., Louisiana Tech University, US

Light trapping is a useful way of enhancing photovoltaic conversion via any means by which light not converted to electricity in a photovoltaic (PV) in one pass through its PN junction, is given another opportunity [...]

Three-dimensional panel configurations to reduce wind load and increase passive convection cooling of photovoltaic surface on solar tracking systems

Edgar R., Cochard S., Stachurski Z., Australian National University, AU

For photovoltaic power systems there is a new class of three-dimensional panel arrangements better adapted to strong wind conditions than contiguous plates of equivalent frontal. These arrangements are unique in having overlapping layers of non-overlapping [...]

Luminescent Solar Concentrator windows for sustainable electricity generation over agricultural land

Corrado C., Leow S.W., Osborn M., Alavi S., Bebout L.E., Prufert-Bebout L., Alers G.B., Prufert-Bebout L., Carter S.A., University of California, Santa Cruz, US

Luminescent Solar Concentrators (LSCs) consisting of a transparent plate embedded with a high quantum yield luminescent dye may be used in conjunction with Photovoltaic (PV) cells to enhance the power output of the cells, thus [...]

New route for growing of ZnO seed layer using SILAR method

Galego E., Serna M.M., Ramanathan L.V., IPEN-CNEN/SP, BR

In this work a new route was applied, it was utilized successively ionic layer adsorption reaction (SILAR) method to growth of the ZnO seed layer with low mis-orientation.

High Temperature Nanostructures for Thermophotovoltaics

Lee H.J., Smyth K., Kim S-G, Massachusetts Institute of Technology, US

A fundamental challenge in solar-thermal-electrical energy conversion is the thermal stability of nano-engineered materials and devices at high operational temperatures. Selective tungsten emitters based on 2-D photonic crystals have been found effective in controlling the [...]

Framework for Quantitative Exposure Assessment of Nanostructured Materials in Occupational Settings

Kreider M.L., Unice K.M., Panko J.M., ChemRisk, US

The purpose of this work was to provide a framework for assessing potential for risk and exposure to nanostructured materials in occupational settings. In doing so, we evaluated the characteristics of amorphous silica and carbon [...]

Occupational Safety and Health Management Systems for the Safe Commercialization of Nano-enabled Products

Heidel D., Segrave A., Baker J., Bureau Veritas North America, US

The value of an occupational health and safety management systems (OHSMS) approach for the safe synthesis of engineered nanoparticles and safe commercialization of nano-enabled products will be presented. An OHSMS framework integrates continual H&S improvement [...]
