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 [...]

Infrared Sensor Interference Isolation for Low-Cost Three-Dimensional Anemometers

Hirano J., Garmire D., University of Hawaii at Manoa, US

The further integration of wind power generation into our power grids from residential and industrial building installations increases the need to gather high spatial resolution wind data. This results in a need for low-cost three-dimensional [...]

Self-Sustaining Meteorological Wireless Sensor Networks

Carland J., Oberbeck A., Umeda M., Cumming J., Wilkey T., Fripp M., Kuh A., Garmire D., University of Hawaii at Manoa, US

Existing electrical grid infrastructure designs cannot reliably handle large intermittent power production fluctuations. Providing an autonomous, self-powered, and easily deployable meteorological sensor network can provide the tools to help mitigate this issue. With proper data [...]

Demand-Side Response from Industrial Loads

Starke M., Letto D., Alkadi N., George R., Johnson B., Dowling K., Khan S., ENBALA Power Networks, CA

With the adoption and integration of renewable resources that are often intermittent in nature, there appears to be an increased need for ancillary services and flexible resources to improve the reliability and efficiency of the [...]
