Use life cycle assessment and risk assessment tools to oversee the development of nanomaterial in building industry

Hu M., Catholic University of America, US

While nanotechnologies offer tremendous benefits for society, they may also pose significant risks. The same properties that make nanomaterial’s promising-those that make them behave quite differently from bulk forms of the same materials-could lead to [...]

Enhancement of GaAs solar cell efficiency by type-II GaSb quantum dots located outside of the depletion region

Afanasev A., Kechiantz A., Lazzari J.-L., The George Washington University, US

Experiments have shown that extrinsic intermediate band (IB) states, for instance, formed by artificial quantum dots (QDs), located in the depletion region participate in electron-hole recombination. This facilitates dramatically the dark current and reduces the [...]

High open-circuit voltage bulk-heterojunction solar cells by using new dendritic acceptor material

Alshahrani T., EL-Betany A., Mabrook M., McKeown N.B., Tai H., Bangor University, UK

Light harvesting solar cells and energy transfer are currently of great challenges for the 21st century in the field of solar cells energy. Academic and industrial scientists are searching for a detailed understanding of light [...]
