Graphene Solar Cells Produce Electricity from Sun and Rain

Mila Luleva — Fri, 08 Apr 2016 16:03:13 +0000

Adding graphene to solar cells makes them generate power from rain. Solar power has been on a continuous rise over the past decade. Rooftop solar is arguably the most common renewable energy source for home use, and solar power plants are arguably the biggest renewable energy large scale generators. But, regardless of all this, there […]

Grätzel's New Dye-Sensitized Solar Cells: Cheaper and More Efficient

Ovidiu Sandru — Wed, 09 Nov 2011 12:34:34 +0000

As our loyal readers already know, Michael Grätzel invented dye-sensitized solar cells 20 years ago, but, despite their low price, these organic cells have proved rather inefficient. However, Grätzel now found a solution for the cells to be cheaper and more efficient. Grätzel’s cells use organic dyes to absorb sunlight, which hits the titanium dioxide […]

Gases Much More Potent Than CO2 Monitored By QUT Master Student’s Project

Mike Sandru — Tue, 31 May 2011 17:20:55 +0000

When you think about air pollution, the first thing popping into your head is probably carbon dioxide, and that is because i’s the most common pollutant. CO2 is actually less powerful than the trio formed by nitrogen dioxide (NO2), nitrous oxide (N2O) and ammonia (NH3). Coming from engines, various combustions, manure and fertilizers, these three […]

Viruses are mostly seen as the bad side of nature, the fallen creation or just that unwanted flu during those sunny days when you were supposed to go play outside. For Angela Belcher viruses are working tools, since she and her MIT colleagues have just found a way to guide some of them so they make solar cells more efficient, by as much as a third.
