Cleaning solar panels often not worth the cost, engineers find

Don't hire someone to wash your dirty solar panels. That's the conclusion of a study recently conducted by a team of engineers at the University of California, San Diego. Their findings were published in the July 25 online ...

Inverted polymer solar cell efficiency sets world record

(Phys.org)—For many years, researchers have strived to reach the goal of 10% efficiency for polymer-based organic photovoltaic (OPV) solar cells, a target widely considered to be the threshold for commercial applications. ...

Generating electricity from vibrations in road surface works

A pilot research project into vibration energy on the N34 provincial motorway near Hardenberg in the eastern Netherlands has shown that vibration energy as a local energy source is a sustainable alternative for the batteries ...

Toward home-brewed electricity with 'personalized solar energy'

New scientific discoveries are moving society toward the era of "personalized solar energy," in which the focus of electricity production shifts from huge central generating stations to individuals in their own homes and ...

Researchers build Quad HD TV chip

It took only a few years for high-definition televisions to make the transition from high-priced novelty to ubiquitous commodity—and they now seem to be heading for obsolescence just as quickly. At the Consumer Electronics ...

Using bacteria batteries to make electricity

(Phys.org) —Their idea is state of the art: Ten Bielefeld students have set their sights on constructing a bio-battery. They want to make use of the bacteria Escherichia coli to convert glucose into energy. With this project, ...
