    The multicrystalline world record solar cell made of n-type HPM silicon with an area of 2 cm x 2 cm. The cell has excellent antireflection properties; therefore the cell appears almost black with almost no detectable grain boundaries.

    The potential of photovoltaics (PV) has not yet been exhausted. Both industry and research continue to work intensively on increasing the efficiency and reducing the costs of solar cells, the basic component of every PV power plant. Now researchers at Fraunhofer ISE have produced a multicrystalline silicon solar cell with 21.9 percent efficiency, successfully bringing the world record back to Freiburg.

    Crystals have applications in a wide variety of fields. Photo of a multicrystalline silicon wafer, which serves as the basis of a solar cell.

    From March 8-10, 2017, an International Conference on Crystal Growth is to be held in Freiburg under the auspices of the German Association of Crystal Growth DGKK and the Swiss Society for Crystallography SGK-SSCR. The conference, jointly organized by the Fraunhofer Institute for Solar Energy Systems ISE, the Crystallography department of the Institute of Earth and Environmental Sciences at the University Freiburg and the University of Geneva, is to be held in the seminar rooms of the Chemistry Faculty of the University of Freiburg. Furthermore, the Young DGKK will hold a seminar for young scientists at Fraunhofer ISE on March 7, 2017.

    TPedge module with 2 mm thick glass undergoing distributed load test.

    The TPedge concept reduces the material and production costs of PV modules, since encapsulation foils and the lamination process are no longer needed. At the same time, the aging stability of the PV module increases appreciably. In the project “TPedge,” researchers at Fraunhofer ISE together with their partners have developed processes so that the innovative PV modules can be manufactured on an industrial scale.

    TABSOLAR component made of Ultra-High Performance Concrete (UHPC), manufactured via the membrane vacuum deep-drawing process.

    When integrating renewable energy into the building envelope, solar thermal plays a significant role. So far, solar thermal products were generally based on metal components that conduct heat, absorb a high fraction of solar radiation and emit little infrared radiation to prevent thermal loss. Using this state of the art technology, building integration and architectural aspects are however often neglected. In the »TABSOLAR II« project, Fraunhofer ISE, together with partners, is following the new approach to produce solar-thermal collectors made from ultra-high performance concrete. Suitable procedures have already been tested. The project team is now working on the next steps for later product manufacture and connection concepts for building integration. The current developments will be presented at the BAU 2017 trade fair.

    The web-based data visualization of the energy monitoring platform MONDAS provides a multitude of displaying possibilities that can be configured and structured easily by the user.

    Through optimized operation management, up to 30 % of building energy consumption could be saved. Even low-cost investment measures could result in optimization and significant reduction of costs. In order to save energy, a detailed analysis of the building operation is necessary. For this purpose, Fraunhofer ISE developed the energy monitoring platform MONDAS, which provides all components necessary for collecting, saving, processing and visualizing relevant time-series data regarding building operation. The platform successfully pools software modules to a high-performance overall system. It will be presented at the BAU 2017 trade fair.

    Visualization of a façade with strip collectors.

    Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
