Scientists at the U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL) have set a world record in solar cell efficiency with a photovoltaic device that converts 40.8% of the light that hits it into electricity. This is the highest confirmed efficiency of any photovoltaic device to date. The inverted metamorphic triple-junction solar cell was designed, fabricated and independently measured at NREL. The 40.8% efficiency was measured under concentrated light of 326 suns. One sun is about the amount of light that typically hits Earth on a sunny day. The new cell is a candidate for the space satellite market and for terrestrial concentrated photovoltaic arrays, which use lenses or mirrors to focus sunlight onto solar cells.

""Private companies like Anwell, Hanergy and Hareon Solar have many photovoltaic projects in the pipeline and they are expected to pump billions of dollars in the industry to take full advantage of the conducive environment and regulatory policies in China." "

Last week the Spanish government announced plans to cut subsidies for solar photovoltaic (PV) power by about 75%. Although the nation expects to surpass its 2010 goal for installed solar by four fold, the down side is that generous subsidies for the industry have resulted in a ballooning tariff deficit for the country, which has risen to 4.85 billion euros, upfrom 745 million last year. Reuters reported that lending to the Spanish photovoltaic plants has risen to $3.59 billion in the year to day, up from $230.9 million euros last year and $192.44 million in 2006. As a result, the Spanish government will as the energy regulator to cap subsidies for new PV solar capacity at 300 megawatts (MW) per year--200 MW for rooftop systems and 100 MW for ground-mounted systems, which have been the highest growth area. CSP has been slower than PV technology in its emergence on the renewable energy scene, but expectations for the technology, which focuses the heat of the sun to produce steam to drive electricity producing turbines. Projects underway in the U.S. and Spain are expected to produce electricity that is cost-equivalent to electricity produced from burning coal or natural gas.

The solar industry and semiconductor industry are intimately connected. Both industries rely on silicon and both use much of the same processing technology and supply chain to produce their products. Nowhere has this connection been on better display than last week at the Moscone Center in San Francisco California, where the Intersolar North America made its debut in conjunction with SEMICON West 2008. The show provided an opportunity for those in the two industries to connect and allowed those companies that work in both spaces to showcase their collective efforts. According to Chris O'Brien, Head of Market Development and Government Relations for North America for Oerlikon Solar, holding the two conferences together gave companies greater exposure and showed the promise of the U.S. solar market. In recent months a number of traditional semiconductor companies including Intel and National Semiconductor have made announcements that they are making plans to enter the solar industry in one way or another. Intel spun off it's solar research area into a new solar company called SpectraWatt. National Semiconductor announced that it will be introducing it's first solar product, SolarMagic, that could raise the efficiency of residential and industrial solar systems. Kevin Kayser, Senior Marketing Manager at National said that he product will be targeted at installers and integrators and much planning went into the company's decision to enter the solar space. "Photovoltaics currently has less than 1% of the energy market, but we think it has potentially one of the fastest growth rates of any alternative energy source. Now certainly we're looking at wind, we're looking geothermal, we're looking at other sources, but from an electronics point of view we saw that we had the most immediate potential impact in solar photovoltaics," Kayser said.

DuPont Photovoltaic Fluoromaterials (PVFM) announced that it has signed a Technology Licensing Agreement with Toppan Inc. Printing Co. LTD, located in Tokyo, Japan, to commercialize its new backsheet for solar photovoltaic (PV) modules. This technical and business deal with Toppan is in line with the PVFM strategic intent to significantly increase the availability of DuPont Tedlar films and backsheet for the fast growing PV market, according to the company. "This collaboration combines DuPont's proprietary technology for Tedlar polymer in backsheets, with Toppan's unique coating capability," said Kelly Kolliopoulos, global business manager of DuPont's Tedlar Division. "We view the new backsheet technology as complementary to our continuing activities to increase the supply of Tedlar films in order to meet the industry's growth and demand for Tedlar."

Sierra Pacific Power and Nevada Power Company have announced that they are expanding their SolarGenerations renewable energy programs to include cash incentives for wind and hydroelectric power systems as well as solar photovoltaic (PV) systems. Both Nevada utilities are wholly-owned subsidiaries of Sierra Pacific Resources. "These projects deliver benefits on many levels: they reduce energy bills, provide learning opportunities, help the environment, and increase our energy independence by taking advantage of abundant natural energy sources right in our own backyard." -- John Hargrove, Program Manage, Sierra Pacific & Nevada Power The last session of the Nevada State Legislature made the SolarGenerations demonstration program permanent, doubling the total amount of installed photovoltaic energy eligible for rebates from 1,900 kilowatts (kW) to 3,760 kW, and adding the new WindGenerations and HydroGenerations programs. Together, these programs are called RenewableGenerations.

Solar Thin Films, Inc. (OTC BB:SLTN.OB), a developer, manufacturer and marketer of manufacturing equipment for the production of "thin-film" amorphous silicon photovoltaic modules, has entered into a strategic alliance and cross license agreement with Amelio Solar Inc. \n\nUnder the agreement, Solar Thin Films will market and sell photovoltaic products using copper indium gallium diselenide (CIGS) technology developed and commercialized by Amelio Solar, and has rights to manufacture PV module manufacturing equipment using CIGS technology subject to certain terms and agreements\n

Last week, IBM announced a research breakthrough in photovoltaics (PV) technology that could significantly reduce the cost of harnessing the sun's power for electricity.

"Carbon Nanotubes (CNTs) have not yet met commercial expectations from a decade ago, and now hot on its heels is graphene. Graphene is considered a hot candidate for applications such as computers, displays, photovoltaics, and flexible electronics. IDTechEx market forecasts indicate that CNT and graphene transistors may be commercially available in volume from 2015 onwards, according to the new report \"Carbon Nanotubes and Graphene for Electronics Applications 2011-2021\". According to IDTechEx, the biggest opportunity for both materials is in printed and potentially printed electronics, where the value of these devices that partly incorporate these materials will reach over $44 billion in 2021."

"Their main finding was that companies using low-cost financing to buy PV systems, and households taking out solar-specific loans, can achieve savings of up to 30% compared to leasing a PV system through a conventional third-party owner."

Dwarfed by any of the north African nations, it represents an area slightly smaller than Wales but scientists claimed yesterday it could one day generate enough solar energy to supply all of Europe with clean electricity. Speaking at the Euroscience Open Forum in Barcelona, Arnulf Jaeger-Walden of the European commission's Institute for Energy, said it would require the capture of just 0.3% The scientists are calling for the creation of a series of huge solar farms - producing electricity either through photovoltaic cells, or by concentrating the sun's heat to boil water and drive turbines - as part of a plan to share Europe's renewable energy resources across the continent. A new supergrid, transmitting electricity along high voltage direct current cables would allow countries such as the UK and Denmark ultimately to export wind energy at times of surplus supply, as well as import from other green sources such as geothermal power in Iceland. Energy losses on DC lines are far lower than on the traditional AC ones, which make transmission of energy over long distances uneconomic. The grid proposal, which has won political support from both Nicholas Sarkozy and Gordon Brown, answers the perennial criticism that renewable power will never be economic because the weather is not sufficiently predictable. Its supporters argue that even if the wind is not blowing hard enough in the North Sea, it will be blowing somewhere else in Europe, or the sun will be shining on a solar farm somewhere.
