Using a simple chemical process, scientists at Cornell and DuPont have invented a method of preparing carbon nanotubes for suspension in a semiconducting “ink,” which can then be printed into such thin, flexible electronics as transistors and photovoltaic materials.  The method, which involves treating carbon nanotubes with fluorine-based molecules, is reported in the Jan. 9 issue of the journal Science (Vol. 323 No. 234).

Imagine a manufacturer that took back its products after 25 years of use.  That’s exactly what watchdog group Silicon Valley Toxics Coalition is recommending that the solar industry do in a white paper released on Wednesday.   Solar is a renewable source of energy, and solar panels don’t pollute when they are generating electricity. But the upstream process of making solar panels involves a number of toxic chemicals.  Most solar cells are made out of silicon, the same material embedded in billions of electronic chips. As a result, the burgeoning solar photovoltaics (PV) industry faces an electronic-waste problem. (more…)

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE have achieved a record efficiency of 41.1% for the conversion of sunlight into electricity. Sunlight is concentrated by a factor of 454 and focused onto a small 5 mm² multi-junction solar cell made out of GaInP/GaInAs/ Ge (gallium indium phosphide, gallium indium arsenide on a germanium substrate).  “We are elated by this breakthrough,” says Frank Dimroth, head of the group “III-V – Epitaxy and Solar Cells” at Fraunhofer ISE. “At all times the entire team believed in our concept of the metamorphic triple-junction solar cells and our success today is made possible only through their committed work over the past years.” (more…)

Inexpensive solar cells, vastly improved medical imaging techniques and lighter and more flexible television screens are among the potential applications envisioned for organic electronics.  Recent experiments conducted by Greg Scholes and Elisabetta Collini of University of Toronto’s Department of Chemistry may bring these within closer reach thanks to new insights into the way molecules absorb and move energy. Their findings will be published in the journal Science on January 16. (more…)

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.

Sources inform ”Globes” that German industrial giant Robert Bosch GmbH is considering entering Israel’s solar power industry. The sources added that Bosch executives recently visited Israel and met Minister of National Infrastructures Benjamin Ben-Eliezer and other officials, including executives of solar energy companies.  Bosch is initially interested in supplying equipment and installing thermal and photovoltaic panels at companies and households. Industry sources believe that Bosch may later build solar power projects, possibly as part of a consortium with Israeli companies. (more…)

The solar photovoltaic (PV) industry is clearly in a rapid growth phase. The worldwide industry size was recently estimated at $50 billion. Over the past few years, production capacity is thought to have grown at an average of 48% each year and cumulative global production is now at 12.4 Giga Watts (GW). It is also an industry on the brink of change. New technologies are emerging that seem certain have an impact on the entire shape of the PV industry. (more…)

Cities wanting to remove the guesswork from solar power installations are turning to friendlier technology for citizens. Since typing a street address into a Web site is all it takes to determine how much solar power can be obtained from a rooftop installation, who wouldn’t take a look?  An exemplar is the San Francisco Solar Map that lets residents view buildings that are equipped with solar power. Users also can type their address into the Solar Map site to get an analysis of how much solar power their roof could harness.  (SF Solar map site URL:  http://sf.solarmap.org/) (more…)

Solar stocks in for another stormy year in ’09

As dismal as 2008 has been for solar stocks, next year doesn’t look any brighter.  Funding for solar projects and factory expansions remains scarce, prices on panels are falling faster than expected as supplies jump, and a dramatic drop in oil prices has tempered investor appetite for renewable energy stocks.  There is palpable optimism, however, that the new U.S. presidential administration will move rapidly on legislation to boost demand for alternative energy sources. Still, it remains to be seen how quickly that would get done and what form it will take.  “It will be a tumultuous year for most solar companies,” said Karina Funk, an analyst with Winslow Green Funds in Boston.
