A community portal about Solar cells with blogs, videos, and photos. According to Wikipedia.org: A solar cell is a device that converts photons from the sun into electricity. In general, a solar cell that includes both solar and nonsolar sources of light is termed a photovoltaic cell. Fundamentally, the device needs to fulfill only two functions: photogeneration of charge carriers in a light-absorbing material, and separation of the charge carriers to a conductive contact that will transmit the electricity. This conversion is called the photovoltaic effect, and the field of research related to solar cells is known as photovoltaics.
Professor Guillermo Bazan and a team of postgraduate researchers at UC Santa Barbara's Center for Polymers and Organic Solids (CPOS) have announced a major advance in the synthesis of organic polymers for plastic solar cells. Bazan's team reduced reaction time by 99%, from 48 hours to 30 minutes, and increased average molecular weight of the polymers by a factor of more than 3. The reduced reaction time effectively cuts production time for the organic polymers by nearly 50%, since reaction... Read Full Story
So-called thin-film photovoltaic devices are usually based on mixtures of elements other than silicon — most notably copper indium gallium selenide (CIGS) — applied in a thin layer to plastic, even organic, components. Using nanotechnology and advanced materials science, thin film is able to produce power with a fraction of the materials. Similar techniques are being tried using ultra thin layers of silicon on a glass substrate, reducing what is now a 250 - micrometer (um) - thick wafer to... Read Full Story
Dow Chemical, the chemical manufacturer that plans to release roofing tiles with integrated copper indium gallium selenide (CIGS) solar cells next year, has inked a multimillion dollar research alliance with Caltech to experiment with next generation solar cells.
The goal will be to identify relatively earth-abundant materials
that can be exploited to develop future, cheaper solar cells. Caltech
doesn’t get the same sort of adulation in the…

1394 Industry Association (1394 Trade Association) executive director James Snider, said: "Symwave's FirePHY-800 will lead to a new generation of high-speed storage devices, providing consumers with a myriad of tangible benefits. We are very pleased to see Symwave to provide a robust and reliable high-speed 1394b firewire hard drive dock . Users of multimedia content demand is growing rapidly, requiring larger and faster external storage devices. " Many have a FireWire 800 (1394b) interface... Read Full Story
Usually when we meet, we are all the side show PowerPoint presentations, while express their views. Person in charge while also recording the discussion to everyone for the timely revised and finalized, it is very hard. In fact, we can use wireless presenter trackball mouse to do "e-notes", you can show your presentation, while the content can be easily recorded in the slide. In this way, we both see the actual playback also capable of writing the record, and all work is done simultaneously... Read Full Story
In the fossil energy and carbon emission reductions under the constraints and other issues, people began right after several big new energy to pursue. The hottest areas in which course ought to solar energy . Soalr energy produced by the Earth for an hour, enough to the world's annual energy needs. This is precisely why the use of solar energy as our dependence on oil from the ultimate way. If we are able to save resources, utilization of solar energy, access to energy net profit, we truly...

Ascent Solar Technologies,
which makes copper indium gallium selenide (CIGS) solar cells, says it
has boosted the efficiency on its commercial solar cells and modules
once again.
Back in November, it’s champion solar cell – the best of a
manufactured bunch – exhibited around an 11 percent efficiency and the
best modules came with a 9.5 percent efficiency, according to Farhad
Mogahadam, CEO, in an interview. In March, the company could…

Solar cells could soon be produced more cheaply using nanoparticle “inks” that allow them to be printed like newspaper or painted onto the sides of buildings or rooftops to absorb electricity-producing sunlight.
Brian Korgel, a University of Texas at Austin chemical engineer, is hoping to cut costs to one-tenth of their current price by replacing the standard manufacturing process for solar cells – gas-phase deposition in a vacuum chamber, which requires high... Read Full Story
