AZUR P2 photovoltaic modules still offer 98% of their original capacity after 20 years
"AZUR 2P, a completely new type of coating for photovoltaic modules, is the result of continued research and development. The coating process protects solar cells from extreme external factors - for example sand storms in the desert - and the surface coating is water-repellent and possesses both self-cleaning and self-repairing properties. In case of any damage to the surface, the coating flows to the relevant area and seals it. The area will then harden to a smooth finish within just a few hours. In other words: AZUR 2P provides reliable protection against abrasion caused by sand, dirt etc., and also keeps moisture, acids and alkalis at bay, providing effective protection against material aging. Traditionally, aging and capacity loss for solar modules had to be calculated at about 1% per year, e.g. approx. 10% in ten years. AZUR P2 effectively protects against radiance and hazing, thus reducing the degradation process tenfold. That means that after 20 years of use, efficiency will no longer be reduced to 80%, but instead will remain at a sensational 98%, revolutionising not only life expectancy, but also ROI. The UV resistant coating will be made available in a wide variety of RAL colours. Depending on individual requirements, the module can be offset in contrasting colours in accordance with building specifications, or can be made virtually invisible - for example in projects related to cultural heritage. This point in particular can make the difference in terms of authorisation procedures."
The desert lives!
Bend Sauter believes that photovoltaics will give new meaning to the old phrase 'the desert lives'. Regions like the Sahara will become available for utilisation as a highly efficient global energy resource, and at the same time provide much needed funding for economically underdeveloped regions in Africa, explains Sauter. As a result, the aspirations advocated by both Sauter and his colleagues, to bring together economy and ecology through efficient photovoltaics, are brought to fruition.
The power coating AZUR 2F opens up new photovoltaic application areas on rooftops and building surfaces
With AZUR 2F, the coating with only 1mm minimum thickness, AZUR Solar presents a highly efficient solar cell module at the Intersolar 2009, which can be installed on just about any roof with minimum effort, providing a capacity of 92 Wp. Due to its particularly low weight of 1kg/m2, AZUR 2P is ideally suited for large roof areas or lightweight constructions, and makes available new application areas. AZUR Solar's CEO explains: "amorphous silicon solar cells are laminated onto a flexible, unbreakable plastic foil. The cells are then encapsulated and bonded permanently. The particularly high yield of 92Wp can also be reached in solutions, where two solar cells are mounted on top of each other for different spectral ranges". 'Installation' is easily carried out by means of any double-sided adhesive tape commonly used by certified roofers. The flexible coating can be moulded to any roof or area, and provides an additional protective layer when used over the entire surface. No points of entry remain for wind or storm, while simultaneously providing high clouding tolerances.
Pioneering in more than one area
Matthias Klopstein, executive manager and CTO concludes: "We think that by presenting AZUR 2P at this leading global fair for solar technology, we can initiate a threefold peaceful revolution in terms of technology, economy and ecology that will have far reaching, if not global impact. In particular, areas which were only partially usable for energy production from sun light, e.g. the Sahara Desert, can now be made widely accessible. And our power coating AZUR 2F also revolutionises the area of photovoltaics for roof areas that were previously inaccessible".
