Innovative concentrated photovoltaic module has housing made of strong, robust DuPont™ Rynite® PET

10.09.2008
The housing for a new and innovatively-designed concentrated photovoltaic module, developed by Concentración Solar La Mancha S.L., of Manzanares (Ciudad Real), Spain, is moulded from DuPont™ Rynite® polyethylene terephthalate (PET).

The material was selected due to its exceptionally low warpage, high stiffness and excellent electrical insulating properties. One of the first commercial installations of the CPV modules is scheduled for September 2008 at the ISFOC (Instituto de Sistemas Fotovoltaicos de Concentración) in Puertollano (Ciudad Real), with plans for a second, 1 MW-rated unit in Castilla La Mancha Community in due course.

The large housing for the concentrated photovoltaic module, measuring 83.3 cm x 56.5 cm, is moulded from DuPont™ Rynite® polyethylene terephthalate (PET) due to the material’s good dimensional stability, low distortion, attractive surface qualities and excellent melt flow.

Concentrated photovoltaic ( or CPV) uses mirrors or lenses to ‘concentrate’ or focus light from a relatively broad collection area onto a small area (as little as 1 sq. cm) of active semiconductor PV material based on Group III and V elements in the periodic table. These systems show very high cell conversion efficiencies of over 36 percent.

The concentrated photovoltaic modules, developed by the Spanish start-up company Concentración Solar La Mancha S.L., consist of six concentrator elements and automatically track the sun’s movement across the sky to within 0.2° of accuracy. Such precision enables them to achieve efficiency levels of 20 to 24 percent in terms of electricity production, compared to 15 to 16 percent for modules with conventional silicon cells.

They are housed and supported in a frame moulded from a mica- and glass-reinforced grade of DuPont™ Rynite® polyethylene terephthalate (PET), selected as an alternative to powder-coated aluminium. “We were clear from the outset that we wanted to replace metal with a high performance polymer due to the benefits associated with the change, including corrosion resistance, design flexibility and lower processing cost and material costs. Through the integration of additional functions in the housing, we were able to reduce the number of manufacturing steps,” explains Miguel Trinidad Aragon, CEO of Concentración Solar La Mancha. Rynite® 935 BK505 was chosen for the application due to its exceptionally low warpage, high stiffness and excellent electrical insulating properties. Exposed to around-the-clock outdoor weather conditions, the material was required to provide excellent heat (temperatures of up to 85 °C) and UV resistance, as well as the structural support required for the entire CPV module to withstand high winds.

Fundamental to the project’s success has been the close working partnership between plastic injection-moulding specialist Teknia Plasticos Martos S.A.U of Jaén, Spain, Concentración Solar La Mancha and DuPont. Teknia worked closely with DuPont on mould design – the tool was actually produced in China and prepared within the shortest of time frames thanks to the support of DuPont China. “Despite the housing’s large dimensions (83.3 cm x 56.5 cm), complicated shape and the required wall thickness (3 mm), the excellent melt flow of Rynite® ensures the uniform filling on the mould cavity and the consistent production of moulded parts with good dimensional stability, low distortion and attractive surface qualities within short cycle times,” comments David Peña, development leader at Teknia Plasticos Martos.

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...

Im Focus: Optoelectronic Inline Measurement – Accurate to the Nanometer

Germany counts high-precision manufacturing processes among its advantages as a location. It’s not just the aerospace and automotive industries that require almost waste-free, high-precision manufacturing to provide an efficient way of testing the shape and orientation tolerances of products. Since current inline measurement technology not yet provides the required accuracy, the Fraunhofer Institute for Laser Technology ILT is collaborating with four renowned industry partners in the INSPIRE project to develop inline sensors with a new accuracy class. Funded by the German Federal Ministry of Education and Research (BMBF), the project is scheduled to run until the end of 2019.
