  • Low-Temperature Interconnection Technology for Solar Cells


    Lead-free soldering allows for an RoHS-compliant interconnection process on conventional stringer equipment. Additionally the temperature can be reduced to < 220 °C if desired. Using lead-free solder alloys and appropriate flux, creating mechanically stable solder joints on the metallization of temperature-sensitive solar cells can be achieved.

  • Outdoor Performance Lab – Precise Evaluation of PV Modules


    Reliable measurement data are essential for determining the performance of PV modules. Fraunhofer ISE’s solar test sites enable precise collection of all relevant monitoring data. Together with classical laboratory tests, they provide valuable information on the possible degradation and the expected lifetime yield of PV modules in different climatic zones and allow their comparative evaluation.

  • Dual Use of Land with Agrivoltaics


    The energy transformation requires a massive expansion of solar electricity production, combined with a high demand for space. The problem for ground-mounted systems: Agricultural land is a very limited and valuable resource. Agrivoltaics solves this conflict by enabling food production and electricity generation on the same area.

  • Floating Solar Power Plants


    Depending on the scenario, a photovoltaic expansion of 300 to 450 GWp is needed in Germany to ensure the success of the energy transition. Due to the limited agricultural land, land-neutral solutions must be developed. Floating PV refers to photovoltaic power plants mounted on floating bodies on standing water or at sea.

    In order to determine the solar radiation potential of passenger cars, we are currently investigating and measuring solar radiation on German roads as part of a citizen science campaign with 80 vehicles. The data will be used in new simulation models for solar radiation on traffic routes. This would allow drivers to calculate how far they could drive with solar energy, at what time and on which route.

  • Solar Roofing Modules Replace Roof Tiles


    According to a study by Fraunhofer ISE, photovoltaic systems on Germany’s roofs have a technical potential of approx. 560 GWp. So far, rooftop systems have mostly been installed on house roofs. However, with a widespread expansion of rooftop solar installations, there is a risk that the public’s acceptance of photovoltaic systems could decline. One solution is to use integrated solar modules instead of roofing tiles, which are visually hardly distinguishable from conventional roofing tiles and produce solar power at the same time.

  • Schwimmende Solarkraftwerke


    Für das Gelingen der Energiewende wird in Deutschland – je nach Szenario – ein Photovoltaik-Ausbau von 300 bis 450 GWp benötigt. Aufgrund der begrenzten landwirtschaftlichen Nutzfläche müssen flächenneutrale Lösungen entwickelt werden. Floating PV bezeichnet Photovoltaik-Kraftwerke, die auf Schwimmkörpern auf stehenden Gewässern oder auf dem Meer angebracht sind.
