A Santa Barbara, California, company called Solar3D plans to make silicon solar cells that are more efficient than conventional cells by borrowing the light-trapping concept behind optical-fiber technology. The company claims that its three-dimensional design will funnel light into silicon and keep it trapped—giving the material more time to convert it into electricity. Silicon has a theoretical maximum light-to-electricity conversion efficiency of 29 percent, but panels on the market today are only 15 to 18 percent efficient. Three-Dimensional Design Leads to Better Solar Cells
New Solar Panels Produced at Less Than $1 Per Watt Solar panels that cost less than $1 per watt to produce are on their way, as Colorado State University's new method for low-cost, high-efficiency solar panels looks set to begin mass production. The panels will be made by AVA Solar, and production should start towards the end of next year at a huge factory employing 500 people.The cost reduction comes from the new, continuous manufacturing process which uses cadmium telluride thin film rather than the more expensive crystalline silicon. Once manufactured, the cost to buyers could be brought down to $2 per watt, which is roughly half the current cost of solar panels. The process is also greener, with less wastage than previous systems.
HelioVolt: Solar Innovation Powering a Sustainable World
Within a few years, people in remote villages in the developing world may be able to make their own solar panels, at low cost, using otherwise worthless agricultural waste as their raw material. That’s the vision of MIT researcher Andreas Mershin, whose work appears this week in the open-access journal Scientific Reports. The work is an extension of a project begun eight years ago by Shuguang Zhang, a principal research scientist and associate director at MIT’s Center for Biomedical Engineering. Zhang was senior author of the new paper along with Michael Graetzel of Switzerland’s École Polytechnique Fédérale de Lausanne. In his original work, Zhang was able to enlist a complex of molecules known as photosystem-I (PS-I), the tiny structures within plant cells that carry out photosynthesis.

Photovoltaics Photovoltaic SUDI shade is an autonomous and mobile station in France that provides energy for electric vehicles using solar energy. Photovoltaics (PV) is a method of generating electrical power by converting solar radiation into direct current electricity using semiconductors that exhibit the photovoltaic effect. Photovoltaic power generation employs solar panels composed of a number of solar cells containing a photovoltaic material. Mainstream materials presently used for photovoltaics include monocrystalline silicon, polycrystalline silicon, amorphous silicon, cadmium telluride, and copper indium gallium selenide/sulfide. Due to the increased demand for renewable energy sources, the manufacturing of solar cells and photovoltaic arrays has advanced considerably in recent years.
Spin-cast quantum dot solar cell built by the Sargent Group at the University of Toronto. The metal disks on the front surface are the electrical connections to the layers below. Quantum dot solar cells are an emerging field in solar cell research that uses quantum dots as the absorbing photovoltaic material, as opposed to better-known bulk materials such as silicon, copper indium gallium selenide (CIGS) or CdTe. Quantum dots have bandgaps that are tunable across a wide range of energy levels by changing the quantum dot size. Quantum dot solar cell

Posted by Ryan Scott There are many new forms of green energy, but perhaps none as interesting as the Cool Earth Solar “Balloon.” Here’s the concept behind the design: An inflatable plastic thin-film balloon (solar concentrator) is created Upon inflation, the balloon focuses sunlight onto a photovoltaic cell held at its focal point The design produces 400 times the electricity that a solar cell would generate without the Cool Earth’s concentrator Cool Earth Solar: News Archive
Tamera - SolarVillage We did it! We have a new workshop! We spent the last two weeks getting the machines, tools and materials from Jürgen Kleinwächter's workshop into the new shelves in our workshop. It fits perfectly! So far, with all of the big machines, workbenches and much of the materials and infrastructure in place, and a good deal of the hand-tools, it is striking how much MORE space we have to work than ever before.
If you live anywhere in America other than the shores of the Pacific, you are probably sweating right now. A lot. And it's likely that the paint job and materials on your building's roof are making it worse. As we've reported on GOOD before, painting white the black roofs that top many of American cities can deflect 70 percent more sun, keeping interiors cooler, reducing the urban heat island effect, and curbing global warming. This Is Why We're Hot: Sun-Absorbing Black Roofs Need a Coat of White Paint - Cities

Solar Power Rocks! Use Solar Energy to Power your Home, your Business, your LIFE! Our environment and economy are in rough shape – We think solar power can help both. While some of the brightest minds have created innovative technologies to help us overcome pollution and our reliance on imported non-renewable resources, we face an enormous challenge – implementation We noticed a lack in the accuracy and availability of state-specific solar incentives online. Moreover, many solar panel payback calculations provided by various sources were flat out wrong. This left us to reason many of those interested in solar may have given up or were frustrated by the task of seeking out these important facts. In 2007, we created SolarPowerRocks.com to provide the clear, easy to understand information people need to install solar energy across the country.
Welcome to the first website that makes solar energy accessible and understandable to you. The Solar Guide aims to give consumers the practical information they want, about buying solar and renewable energy systems. Get straight facts about solar and renewable energies. We'll also tell you everything you want and need to know about solar energy systems, including solar panels and solar water heaters, plus other alternative energy sources such as wind energy systems and geothermal energy.

Government to slash subsidies for solar power
5 July 2011Last updated at 19:00 ET By Nick Rosen Author and film-maker Zhu Gongshan's company GCL-Poly is now China's largest producer of polysilicon, the main material in solar panels There is little information in the public domain about energy company boss Zhu Gongshan - and one gets the impression he prefers it that way. While other billionaires invited me to their offices or even their homes, Zhu preferred to talk in a hotel suite hired solely for the occasion. China's super-rich: Zhu Gongshan
