Revolutionary Solar Cell Absorbs More Sunlight, More Efficiently

Janina Lazo-Cruz — Thu, 29 Nov 2012 13:10:30 +0000

Based on a computer model developed by MIT engineers, it is possible to capture a broad spectrum of sunlight using a very thin film (about 6 Angstroms) of molybdenum disulfide (MoS2) that is poked with a microscopic needle at the center, creating a field of varying (non-uniform) elastic strain, and thus, varying band gap across […]

A solar cell developed at the Unversity of Toronto, Canada, is able to harvest both visible and infrared light and can theoretically achieve efficiencies of up to 42 percent. Their tandem solar cell is based on colloidal quantum dots (CQD), and the team has been led by Professor Ted Sargent, a Professor of Electrical and Computer Engineering.

A team of researchers about whom we've been talking about more then two years ago, from the Idaho National Laboratory in Idaho Falls, has made advances in the study of a special kind of solar cells that can harvest the solar power even at night, in the absence of visible light.

If we learned to fly from birds, and to swim from fish, then why shouldn't we learn to extract our energy like plants do? The Australian Shark Bay gives us a clue on how we could.

Plastic Solar Cells Going to Make Their Market Breakthrough

Cristi — Tue, 05 May 2009 19:41:08 +0000

Even though plastic solar cells are cheaper to produce and they have some advantages like lightweight and flexibility , they still miss one important thing: the efficiency. Researchers are optimist that in the years to come, the polymer solar cells will be able to compete from the efficiency point of view with the silicon solar cells as well taking into account the fact that plastic solar cell have improved their efficiency each year.

Gold Nanoantennas Could Harvest Solar Power at Night Time

While the most high performance classic solar cells only use up to 20% of the solar power falling onto them, researchers from DoE, the laboratory from Idaho, found out a way to capture much more from the Sun's energy, the invisible light spectrum, even at night.
