USPA NEWS - Royal DSM, the global Life Sciences and Materials Sciences company, today announces that it has acquired the SolarExcel company. Based in Venray (Netherlands) SolarExcel has developed a proprietary light trapping technology that can significantly increase the efficiency of solar panels.
With the acquisition DSM expands its growing portfolio of solar energy enabling technologies. Financial details of the acquisition are not disclosed.

SolarExcel BV started in 2007 with the development of its proprietary light trapping technology. This technology consists of a textured polymeric sheet that can be laminated to the (glass) cover of a photo voltaic (PV) module. The textured surface causes light to be guided towards the active layer of the module, significantly reducing the loss of light caused by internal reflection. The technology works under all angles of incidence and also improves the efficiency of solar modules with a suboptimal orientation.
Although development is ongoing, the gain in module output is estimated to be in the range of 6-12% depending on the type of PV panel. In addition to increasing panel efficiency, the technology potentially allows for cost reductions through simplifications in module design.

The company will be integrated into DSM Advanced Surfaces, part of the DSM Innovation Center. DSM Advanced Surfaces was established in 2010 to build a portfolio of technologies to enable and improve the capture of solar energy. DSM Advanced Surfaces currently is an important supplier of anti-reflective coatings with its proprietary KhepriCoat® product.
KhepriCoat® anti-reflective coating for solar glass features best in class light transmission combined with excellent outdoor durability. In 2012, DSM expanded the production capacity of KhepriCoat® at its site in Sittard-Geleen (Netherlands), responding to growing global demand.

Ben Slager, CEO of SolarExcel says: “I am excited that SolarExcel has become part of the DSM family and DSM is dedicated to further develop this promising light trapping technology. With DSM´s broad and in-depth knowledge in Materials Sciences and commitment to the solar industry, I am convinced that this technology will make an important contribution in the worldwide growth of solar energy.“
