In our series “An Espresso with …” we regularly carry out interviews with engaging people from the field of renewable energy. In this episode we welcomed three young scientists at our coffeetable. Ismail Kaaya, Djamel Mansour and Amantin-Panos Mehilli are scholars of the EU Horizon 2020 research project “SOLAR-TRAIN“. They reported on their initial experience at Fraunhofer ISE.

SolarWorld is only the latest bankrupt PV manufacturer in Germany. Many now wonder: What is the matter with photovoltaics in Germany and what is next? When trying to answer these questions, we have to look at three sectors: Politics, economy and technology. In the technical and economic sector, photovoltaics (PV) is on a triumphal march worldwide. Along with wind energy, it will be a keystone of the climate-friendly energy supply of the future. However, the capital-oriented market economy does not regard the fact that a local and sustainable production of solar modules is important.
The basic principle of solar-thermal collectors is simple. All utilize sunlight to warm up a heat transfer medium and thereby make heat energy available. Some supply households in our latitudes with warm water and solar thermal heating. Other technological variants are located in the sun belt of the earth. Those feed power turbines with water steam and supply whole regions with electricity. Over the years, the technology has found new applications and the variety of solar-thermal products is enormous. Accredited testing institutions play a significant role to ensure the quality of solar collectors and other thermal heat generators, such as heat pumps, and to provide transparency on the international market. Dr. Korbinian Kramer, Head of the TestLab Solar Thermal Systems at Fraunhofer ISE in Freiburg, describes how a testing institution acts in such an environment and continues to reinvent itself.
The Silicon PV – International Conference on Crystalline Silicon Photovoltaics came back to Freiburg from 03rd to 5th of April where it began in 2011. The conference series was founded with the goal of offering an outstanding high-class scientific program on advanced technologies, materials and concepts for crystalline silicon solar cells and modules. This year, 370 participants from 25 countries have registered to attend. Ralf Preu, Ph.D. Director Division PV Production Technologies and Quality Assurance is chairman of the conference. In an interview with Innovation4E he talks about the conference’s highlights, new technologies and the challenges of the PV industry.
Since 2014 Fraunhofer ISE maintains the Energy Charts portal (www.energy-charts.de) which displays current energy data visually in interactive graphs and diagrams. With just a few clicks, one can view illustrative diagrams that provide information about the share of renewable energies in the power supply in Germany. Prof. Bruno Burger is the initiator and developer of the Energy Charts. We spoke with him about the project and the newest developments. Read more →
