Thin-Film Solar Cells: Sharp develops Mass-Production Technology for Triple-Junction-Technology

Sharp Corporation has developed mass-production technology for stacked triple-junction thin-film solar cells, the company reports in a press release. Sharp turned a conventional two-active-layer structure (amorphous silicon plus microcrystalline silicon) into a triple-junction structure with amorphous silicon (two active layers) and microcrystalline silicon (single active layer). This new architecture boosts cell conversion efficiency from 11 % to 13 % and module conversion efficiency from 8.6 % to 10%. Industrial production is slated to begin in May 2007 at Sharp’s Katsuragi Plant in Nara Prefecture.

Creating two amorphous silicon active layers significantly increases voltage levels, and structuring the cell to have three active layers in combination with microcrystalline silicon decreases light-induced degradation (drop in conversion efficiency)The result is high conversion efficiencies at the top levels in the industry, with cell conversion efficiency at 13% and module conversion efficiency at 10%, Sharp emphasizes.

Large-scale production without additional equipment
Normally, the shift from a two-layer structure to a three-layer structure would demand an increase in production equipment, but these newly developed thin-film solar cells can be fabricated on the same equipment as conventional tandem (two-layer) cells, Sharp illustrates. Consequently, the shift to multiple active layers enables increases in conversion efficiencies and thus a lower price per watt without the need for expensive, large-scale equipment. In addition, using this triple-junction thin-film solar cell in Sharp’s Lumiwall Illuminating Solar Panel, a combination of solar module and LEDs, or in transparent thin-film solar modules designed for use as architectural elements, will enable higher power output. Expectations are high that this new development will expand the range of applications for these products even further.
Sharp has ranked No. 1 in the world for solar cell production for the past six years in a row. As the world leader, Sharp will press ahead in the future with aggressive development of thin-film solar cells in addition to crystalline solar cells based on technological capabilities accumulated over long years of experience in this field.

aleo solar signs contracts in Germany worth EUR 35 million

aleo solar AG, producer of solar modules can already report firm orders in Germany for 2007 of EUR 35 million. These orders are for the sale of aleo modules, the company announces in a press release. Corresponding agreements were signed with a number of fitters at the end of December and will take effect in 2007. "Our business in Germany picked up again significantly in Q4. We were able to run down our inventories to a large extent and will exceed our forecasts for the year" Heiner Willers said, member of the Management Board of aleo solar AG. In a buyer’s market, module prices now again would be seen as an incentive for investment, while the mild winter has allowed fitters to continue working to date.

Bread-and-butter business in Germany; new facility in Spain

Jakobus Smit, the second Management Board member of aleo solar AG, is also cautiously optimistic: "At a strategic level, we are driving forward the internationalisation of our business at full speed. We finished construction of our facility in Spain at the end of last year as planned, and it has now started production. Our bread-and-butter business in Germany is going well. Our total production capacity of 100 MW (Prenzlau 90 MW, Barcelona 10 MW) gives us precisely the capacity we need to service the continued market upturn."

East Germany turning into a "Solar Valley"

The current debate about the reliability of energy supplies underlines the need for renewable energies, and East Germany is turning into a "Solar Valley". aleo solar AG, which is headquartered in Prenzlau, Brandenburg, has approximately 280 employees and holds a 19 % stake in the thin-film facility in Brandenburg on the Havel that is currently being constructed by Johanna Solar Technology.

ESTIF: EU Commission fails to deliver Directive proposal on renewable heating and cooling

Renewable heating and cooling is now definitely recognised as essential for the future of Europe’s energy supply, this is good news from the Renewable Energy Roadmap, presented on January 10th by the European Commission. Bad news is that the Commission did not deliver the Directive proposal requested by the European Parliament, the European Solar Thermal Industry Federation (ESTIF) reports in a press release. "We are pleased to see that solar thermal and other renewable heating and cooling technolgies are now fully integrated as a crucial element of Europe’s renewables strategy, at least in the discourse of the Renewable Energy Roadmap" said Mr Raffaele Piria, Policy Director of the European Solar Thermal Industry Federation (ESTIF), “but we are missing concrete measures”.

Joint Declaration for a European Directive to promote Renewable Heating and Cooling.

Until a few years ago, solar thermal was neglected at EU level and by most Member States, though it is one of the most cost effective renewable technologies, which can be directly applied on most of Europe’s buildings. EU Directives have been adopted to promote renewables in the electricity and in the transport sector, but no legislative framework exists for renewable heating and cooling
(RES-H).


Joint Declaration for a European Directive to promote Renewable Heating and Cooling: Picture Source: ESTIF

A broad alliance supported the European Parliament’s resolution

In 2004, ESTIF initiated a campaign to set RES-H on the European agenda. This concern has been endorsed by a broad coalition of renewable and conventional heating industries, NGOs, energy agencies, municipalities, academics and citizens. In February 2006, the European Parliament adopted, by an overwhelming multi-party and cross-country majority, a resolution asking the Commission to present a Directive proposal to promote RES-H, including specific targets at EU and national level.

Industry disappointed about lack of concrete measures

"Almost one year after the European Parliament’s resolution, we are very disappointed that the Commission is not yet prepared to follow up with action and table a Directive proposal with clear targets and measures to promote renewable heating and cooling", said Ole Pilgaard, President of ESTIF. "The European solar thermal market is growing strongly, but still based on very few leading countries. Our industry needs strong and balanced demand all over the EU, to be able to achieve the economies of scale necessary to make solar fully competitive with heating from fossil fuels or electricity", he added.

Specific sectorial targets for Renewable Heating needed

The solar thermal sector argues for a EU renewable heating and cooling Directive, including European and national targets for RES-H as well as a positive legal framework for support measures to be flexibly adopted by each Member State, according to its circumstances. Without specific targets for renewable heating and cooling, investors, citizens and policy makers might continue to overlook the huge, unexploited potential of solar thermal and other technologies. Renewable heating tragets should be accompanied by updated targets for 2020 for renewables in the electricity and in the transport sector, within the framework of the relative existing Directives.

Solar Thermal Action Plan to be published later this month

Later this month, ESTIF will publish an Action Plan for Solar Thermal in Europe, including analysis of success and barriers to growth as well as guidelines for best practice policies. This Action Plan will be presented at the 2007 European Renewable Energy Policy Conference, organised by EREC (European Renewable Energy Council), 29-31 January, Brussels.
