Nanotechnology cuts costs and improves efficiency of photovoltaic cells
Researchers have summarised the most effective ways that nanostructures can improve the efficiency and lower costs of photovoltaic (PV) solar cells in a recent analysis. Sculpting ultra-thin solar cell surfaces at the nano-scale has been found to effectively boost their efficiency. Making solar cells ultra-thin reduces their material costs, but often at the expense of their efficiency. These ...

Greenest pope in history
The green credentials of Pope Benedict XVI were increased yet again when he received an electric car to use within the grounds of the Vatican and his summer residence at Castel Gandolfo. French car maker Renault presented the Pope with his very own white Kangoo, pimped out with the Papal coat of arms on its doors. The Kangoo Maxi van has a 44 kilowatt electric motor and lithium-ion battery ...

High-power, self-cleaning solar panels
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 reflected back into the sky rather than being converted into electricity. Secondly, they get dirty with dust and debris caught on the wind and residues left behind by rain and birds. Now, research published in the International Journal of ...

Idea could lead to cheap solar cells using plant waste
Remote communities could eventually make their own solar cells using waste vegetation, thanks to a design developed by researchers in Switzerland and the United States. The technology is inspired by photosynthesis. In plant cells, sunlight separates electrical charges with almost 100 per cent efficiency. Electrical charges must also be separated to create currents in solar cells. For the past ...
