    The Fraunhofer Institute for Solar Energy Systems ISE and teamtechnik, an international leader in production technology, report that it is now possible to connect high efficiency solar cells using electrically conductive adhesives in series production. The results of the joint research project »KleVer« show that the adhesive technology is ready for the market and can be used as an alternative to the widespread soft soldering interconnection technology. Due to the much lower process temperatures of this technology compared to soldering, temperature-sensitive high efficiency solar cells can be connected using adhesives in a gentle and material-saving process. In industrial production, the throughput is only slightly lower than with soldering. The reliability of the adhesive connection was confirmed in tests carried out in a climate chamber.

    Building-integrated photovoltaics (BIPV) places high demands on solar PV module design. The aesthetics and freedom of design are just as important as the module efficiency, and in manufacturing today, a conflict often exists between individualized sophisticated design, high module efficiency and low costs. In the BIPV-Fab project, the equipment manufacturer SCHMID and the Fraunhofer Institute for Solar Energy Systems ISE investigated possibilities for manufacturing customized modules in series production. With the newly developed production concepts, the costs of building-integrated PV modules can be reduced by 35 percent.

  • The Fraunhofer Institute for Solar Energy Systems ISE is presenting innovative solutions and projects on renewable energy storage and grid integration at the Energy Storage Europe, the leading international trade fair for storage in Düsseldorf, Germany from March 13-15. Fraunhofer ISE is presenting at a joint booth of the Fraunhofer Energy Alliance (Hall 8b, booth B39). Parallel to the trade fair, the 12th International Renewable Energy Storage Conference (IRES) and the 7th Energy Storage Europe Conference (ESE) are taking place. They address two thematic foci: the scientific research on storage technology, legal frameworks, network and market aspects (IRES) and the business and finance aspects for the rollout of these technologies to the global market (ESE). Fraunhofer ISE researchers are involved in leading conference sessions and presenting their results in the fields of thermal and electrical energy storage, sector coupling and Power to Gas/Power to X.

    With the transformation of our energy system, the fraction of electricity supplied by fluctuating renewable energy sources, such as wind and solar, will steadily increase. This requires more electric storage capacity and an energy management that responds flexibly. Together with partners, researchers at the Fraunhofer Institute for Solar Energy Systems ISE have set up a novel hybrid energy storage system on Borkum, an island on the North Sea. The system consists of a lithium ion battery and a super capacitor for short term power demands. The hybrid storage is connected to the medium voltage grid with a new type of modular inverter. During the field test lasting one year, the researchers will test and compare the different control strategies in the energy management system.

    The costs of solar thermal power plants are falling, as with the other renewable technologies of photovoltaics and wind. As a result, new power plants are very promising especially in the MENA (Middle East and North Africa) region. Within the framework of the World Bank Middle East & North Africa Concentrating Solar Power Knowledge & Innovation Program (MENA CSP KIP), the Fraunhofer Institute of Solar Energy Systems ISE is laying the groundwork for the market development of concentrating solar thermal power (CSP) with techno-economic analyses and know-how.

    In its role as a flexible energy carrier, hydrogen is an important element of the energy transformation. It facilitates the transfer of renewable energy between the different sectors of, for example, mobility, industrial raw materials, heat or gas. The Fraunhofer Institute for Solar Energy ISE is working to further develop the key technologies for sector coupling, for example, hydrogen generation by PEM electrolysis. Together with industry and energy sector, they are testing the application of these technologies in the practice. The results shall serve to establish important fundamentals on the use of this central energy carrier of the future.

  • The agrophotovoltaics (APV) pilot plant located in Heggelbach near Lake Constance

    Until now, acreage was designated for either photovoltaics or photosynthesis, that is, to generate electricity or grow crops. An agrophotovoltaics (APV) pilot project near Lake Constance, however, has now demonstrated that both uses are compatible. Dual use of land is resource efficient, reduces competition for land and additionally opens up a new source of income for farmers. For one year, the largest APV system in Germany is being tested on the Demeter farm cooperative Heggelbach. In the demonstration project “Agrophotovoltaic – Resource Efficient Land Use” (APV-Resola)” led by the Fraunhofer Institute for Solar Energy Systems ISE, solar modules for electricity production are installed directly above crops covering an area of one third hectare. Now the first solar harvest of power and produce has been collected on both levels.
