The Japan Patent Office announced the results of its survey on trends in solar cell-related patent applications. According to the results, Japanese applicants took the lead in the area of silicon solar cells, while European applicants outpaced the others in the area of organic semiconductor solar cells.  About 7,970 solar cell-related patents were filed around the world during the period between 2000 and 2006. By nationality, Japanese applications accounted for 68.4%, far more than European (15.3%) and US (10.6%) applications. (more…)

A new type of dye-sensitized solar-cell module has achieved transparency and color choice, facilitating mass production.  Dye-sensitized solar cells (DSCs) offer various advantages, including freedom of design as well as lower costs and energy consumption, in production processes as compared to silicon-based solar cells.1,2 Monolithic series-interconnected modules—characterized by a structure similar to that of amorphous-silicon solar-cell architectures—are the most promising DSC-module type for mass production.3 However, these modules neutralize the unique transparency advantage of DSCs, because they use black, carbon-based counter electrodes (CEs) as well as rutile-based opaque separators between the photo-electrodes of porous anatase and the corresponding CEs.

The European Patent Office on Tuesday revoked a solar patent issued to a Swiss university in an apparent victory for chip gear-maker Applied Materials Inc (AMAT.O). The solar photovoltaic technology patent was issued to the University of Neuchatel and licensed exclusively to Oerlikon Corp (OERL.VX), a Swiss technology group, Applied Materials said. Oerlikon had alleged the patent was being violated by Germany’s SunFilm AG, a key customer of Applied Materials. (more…)

A Q-Cells (QCLSF.PK) subsidiary that makes micromorph thin-film solar panels is scaling up its production nicely, the company said Tuesday.  Sontor, founded in 2006, started mass production at its German factory last August and rolled out 3.6 megawatts worth of solar panels last year. A solar power plant in Lower Bavaria installed 1.6 megawatts worth of those panels, which are now producing power and hooked up to the grid, the company said. (more…)

Wafer–based solar cells aren’t done yet

The solar industry’s recent growth spurt has shown that success brings new challenges. Once content to salvage silicon scrap from the integrated circuit industry, wafer–based solar cells have become the largest consumer of high–purity silicon. As a result, manufacturers of wafer–based silicon solar cells are caught between rising raw material costs on one side, and less expensive alternative technologies on the other. (more…)

Spain Installed More Than 3GW of Solar in 2008

The latest estimates from the Spanish government show that the new capacity added last year exceeded some expectations by as much as threefold.

How big was the Spanish solar market in 2008? Three times bigger than many analysts have anticipated.  Spain’s National Energy Commission (CNE) this week estimated that about 3.1 gigawatts of solar power were connected to the grid from January through November 2008, said Gordon Johnson, head of the alternative energy research at Hapoalim Securities in New York City.  Since the Spanish program began, around 3.75 gigawatts have been installed there.

South Korea’s LG Electronics will sign a five-year deal this week to buy silicon wafers for solar panels from Norway’s REC Wafer, it said Sunday. The contract, which will be signed on Thursday in Seoul, is worth at least US$340 million and supply will begin in limited quantities next year. Supply will increase over the contract period from 2010 to 2014. (more…)

Waldpolenz energy park is now the biggest solar power plant in Germany

The juwi group commissions the next section of the 40-MW project in Brandis near Leipzig.

The juwi group based in Bolanden in the German state of Rhineland-Palatinate (southwest Germany) set yet another milestone in the development of the world’s biggest photovoltaic power station. Today another section of the Waldpolenz energy park was commissioned. Now
with more than 12.7 megawatts (MW) of production capacity connected to the electricity network, it is the biggest solar power station in Germany. Located in Brandis, east of Leipzig, the juwi group is building a 40-MW solar park based on the most sophisticated thin-film technology. The park is due for completion by the end of 2009. By now some 17,500 steel posts have been put into place and nearly 5,000 aluminum sub-structures constructed which support more than 215,000 solar modules facing south.

Upon completion the solar power station located in the Muldentalkreis
district in the eastern German state of Saxony will generate approximately 40 million kilowatt-hours of clean electricity annually, displacing about 25,000 tons of the greenhouse gas carbon dioxide (CO2) every year. “At a time when the whole world is discussing climate change we are demonstrating the capabilities of renewable energies,” says Matthias Willenbacher, co-head of the juwi group. “Solar electricity is not only good for the environment, it also builds independence from expensive energy imports and creates new jobs. Freestanding installations are an affordable segment of photovoltaics and contribute greatly to that success,” states Willenbacher.

As general contractor juwi is in charge of the planning, logistics and construction site management. The project is creating impetus for the regional and national labor market. During the construction phase up to 100 people, primarily from the region, are involved in the assembly of the Waldpolenz solar power park. Juwi employees are responsible for the operational management, service and maintenance of the park. Solar projects such as this one also create many jobs nationwide in related supplier sectors, such as the solar module, inverter and metal construction industries. Most of the 550,000 First Solar modules for this project, for instance, are being produced in Frankfurt (Oder) in eastern Germany. The inverters and sub-structures are also made in Germany.

Investment in the Waldpolenz solar park amounts to some !130 million. SachsenFonds GmbH has been offering owner’s equity of the project in the form of closed-end funds since late summer 2007. So inhabitants of the region also have the opportunity to participate in this unique project with investments starting at just  5,000. The juwi’s group philosophy is to produce solar electricity at competitive prices as quickly as possible. “With the Waldpolenz station we are demonstrating that there are no longer any limits to photovoltaics,” comments Willenbacher. The solar industry anticipates that in just 8 – 10 years solar electricity will have achieved grid parity, meaning that it will be equal in price or even cheaper than the regular
rates private consumers pay in their electricity bills. A key partner in this endeavor is world-leading thin-film technology company First Solar, which like juwi is actively pursuing speedy market penetration of solar electricity.

The innovativeness of this project is once again underscored by its selection as a designated site in 2008 in Germany’s “Land of Ideas” image campaign. “Germany – Land of Ideas” is an initiative co-sponsored by the German government and commerce and industry, represented by the Federation of German Industries (BDI). German President Horst Köhler is the patron of the initiative. Its mission is to convey positive arguments associated with Germany both at home and abroad and also to highlight the country’s strengths as a business location. The core message of all the campaign’s activities emphasizes “Germany’s leadership through inventiveness”. As part of the campaign juwi will host another open house at the Waldpolenz energy park on June 22nd, 2008. In all likelihood Germany’s Minister for Transport, Building and Urban Development, Wolfgang Tiefensee, will take part in the event.
