  • Minimizing the water consumption of Solar Thermal Power (CSP) plants is an important issue, as this kind of solar power generation is often found in arid areas where the solar irradiation is high. Since these regions are also dusty, the associated yield reduction due to local dust deposition and the costs of cleaning are relevant factors. Particularly in regions lacking water, innovative water saving solutions for cooling and mirror cleaning are needed to significantly reduce the water consumption of solar thermal power plants. Any conflict of water use should be avoided to allow high acceptance of the technology. In the MinWaterCSP project, the Fraunhofer Institute for Solar Energy Systems ISE worked together with its partners on several approaches to reduce the water consumption in CSP plants.

    “I have always been interested in problems that were thought to be unsolvable.” This quote stemming from Prof. Dr. Adolf Goetzberger stands both for his scientific career as well as for his unwavering conviction as founder of Fraunhofer ISE, which he launched and led to success. Goetzberger not only advanced photovoltaic technology, a key pillar of a sustainable future energy system, but from the beginning on also incorporated research on the systemic aspects of the energy transformation at the institute, already perceiving the importance.

    Concentrator Photovoltaics (CPV) has by far achieved the highest efficiency for the conversion of sunlight into electricity. The basis for this latest achievement lies in the special multi-junction solar cells as well as the perfect interplay between the cell and the module optics. In the EU-funded project CPVMatch, a consortium of research institutions and companies has demonstrated how to optimize both of these aspects and thus better exploit the potential of this technology. The achieved module efficiency of 41.4 % is the highest value ever measured for a photovoltaic module.

    The Fraunhofer Institute for Solar Energy Systems ISE and Heraeus are researching and optimizing novel, selectively coated cell connectors in a joint research project. The Selectively Coated Ribbon (SCRTM) cell connector achieves an average gain of 1.9 W in conventional 60-cell solar modules. The connector can be used in industrial PV module manufacturing without system modification and at no extra cost. Fraunhofer ISE has successfully tested modules with the SCR connector in its accredited TestLab PV Modules. Heraeus and Ulbrich developed a process for the production of the efficient cell connector and presented the new product to the professional audience in September 2018 at the EU PVSEC in Brussels.
