    World record for both sides-contacted silicon solar cells

    With a new process for backside contacting, researchers at the Fraunhofer Institute for Solar Energy Systems ISE have set a new record for both sides-contacted silicon solar cells. The scientists achieved an efficiency of 25.1 per cent with an ultra-thin, tunnel oxide back contact. This is applied over the entire surface and does not require complicated processing steps for texturing the cell’s rear side.  more...

    Processing solar cells with lasers

    Laser technology enables solar cells to be produced with greater efficiency. It replaces or eliminates costly processing steps that were previously required. Researchers have developed a method for laser contacting the rear side of solar cells that can be integrated into existing production lines for screen printing solar cells. The new technique enables the cells to be produced at a lower cost, reduces the energy and materials deployed, and eliminates previously required environmentally harmful chemicals.  more...

    Stable grid with 100 per cent green electricity

    In a power grid, the energy provided must always be equal to the power demanded. Only then can frequency and voltage remain stable. Ensuring this is the task of grid operators. But when volatile — meaning not arbitrarily adjustable — energy sources are the main sources of electrical energy, grid operators face a challenge.  more...

    Solar houses scientifically evaluated

    With more than 1,700 buildings realised, solar active houses are no longer a marginal phenomenon. However, what has been lacking until now is a scientific evaluation of this heat supply concept. For this reason, researchers have measured nine solar houses over several heating seasons. Project manager Gerhard Stryi-Hipp has now presented the interim results at the OTTI Symposium on “Thermal Solar Energy”.  more...

    Efficient production of monocrystalline semiconductors

    A Freiberg-based semiconductor manufacturer has now developed a new process that enables up to nine crystals to be grown simultaneously in parallel. This reduces the specific energy consumption for the production by two thirds. The new technological principle can be applied to growing other semiconductor substrates.  more...

    Energy research on course to delivering the energy transition

    The German federal government recently published the National Action Plan on Energy Efficiency. The concept is specifically aimed at winning over all actors in society in achieving greater energy efficiency. A few days later, the German Federal Ministry for Economic Affairs and Energy announced its research funding for the German federal government’s 6th Energy Research Programme. In the BINE interview, Dr Rodoula Tryfonidou from the responsible department in the German Federal Ministry for Economic Affairs and Energy talks about the contribution made by energy research in bringing about the Energiewende – Germany’s energy transition.  more...

    Batteries in the low-voltage grid for more PV energy

    In areas where already a large number of photovoltaic systems are installed, impermissibly high voltages can occur in the power grid on sunny days. It therefore needs to be clarified how the energy generated can be optimally used both technically and economically. One idea is that new charging strategies for batteries can effectively relieve the grid by optimally integrating the energy storage systems.  more...

    Identifying risks and minimising them through regulations

    How safe and reliable are photovoltaic installations with lithium-ion storage systems? In order to find out, scientists are investigating different plant systems. The intention is to identify possible weak points – such as during transport and installation – so that they can be taken into account in future standardisation work.  more...

    Quadruple solar cell achieves record-breaking efficiency

    Researchers have developed a quadruple solar cell that converts 46 per cent of sunlight into electricity. The high-performance cells achieve this record-breaking efficiency in connection with optics that concentrate the light 508 times. If these cells were built in concentrator modules, energy would be produced even more economically in regions with high levels of sun.  more...

    Optimal integration of photovoltaic systems in the grid

    More and more photovoltaic systems feed electricity into the distribution grid. If the electricity generated locally is not used locally by consumers, this can increase the voltage in the grid. In the PV-Integrated research project, scientists are developing inverter control systems which help stabilise the grid. The new models are currently being evaluated in field tests.  more...
