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 [...]

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 [...]

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 [...]

Electrospinning of decorated nanofibers with active cerium oxide nanoparticles

Shehata N., Hassounah I., Meehan K., Camelio J., Virginia Tech, US

Cerium oxide nanoparticles (ceria NPs) attract a great research and commercial interests due to its observable capability to capture radicals and dissolved oxygen molecules. Keeping ceria NPs in active form; containing Ce+3 ions with O-vacancies, [...]

Life cycle considerations for engineered nanomaterials: A case study for nano-enabled coatings on drywall

Sayes C.M., Rothrock G.D., Norton C.A., West C.S., RTI International, US

Engineered nanomaterials are being incorporated into elements of the building industry. Advantages such as increased resistance to ultraviolet damage, wear and fouling of construction materials are relevant to coatings. Particles engineered at the nanometer size [...]
