Small size enhances charge transfer in quantum dots

(Phys.org) —Quantum dots—tiny semiconductor crystals with diameters measured in billionths of a meter—have enormous potential for applications that make use of their ability to absorb or emit light and/or electric charges. ...

Characterizing solar cells with nanoscale precision

(Phys.org) —Researchers from the NIST Center for Nanoscale Science and Technology (CNST) have demonstrated a new low energy electron beam technique and used it to probe the nanoscale electronic properties of grain boundaries ...

Power boosting self-cleaning solar panels

High-power, self-cleaning solar panels might be coming soon to a roof near you. There are two obvious problems with photovoltaic cells, solar panels. First, they are very shiny and so a lot of the incident sunlight is simply ...

Low-priced plastic photovoltaics

Photovoltaic devices, which tap the power of the sun and convert it to electricity, offer a green—and potentially unlimited—alternative to fossil fuel use. So why haven't solar technologies been more widely adopted?

World record solar cell with 44.7% efficiency

German Fraunhofer Institute for Solar Energy Systems, Soitec, CEA-Leti and the Helmholtz Center Berlin announced today that they have achieved a new world record for the conversion of sunlight into electricity using a new ...
