Bouygues Construction Australia and Equans Solar and Storage are trialling an autonomous piling system machine to build French renewable giant ENGIE’s 250 MW Goorambat East Solar Farm in northern Victoria.
Fraunhofer develops contactless method for measuring back-contact solar cells
Scientists at the Fraunhofer Institute for Solar Energy Systems ISE have developed a contactless method to measure the performance of back-contact solar cells, enabling in-line assessment of key parameters such as efficiency, fill factor, and current-voltage characteristics.
Fraunhofer presents solar module cleaning tech using structure-borne sound
Fraunhofer Institute for Digital Media Technology IDMT has developed a solar module cleaning system that uses structure-borne sound and targeted mechanical vibrations to dislodge dust. Researchers will present the technology at Intersolar Europe in Munich from May 7 to 9.
How to combine photovoltaics with rainwater harvesting
Scientists have developed a system that harvests rainwater running off PV panels for household use or hydrogen production. Their analysis showed that, in the southern Sahel, the system can meet both the energy and water requirements for electrolysis, with surplus rainwater covering up to 50% of a household’s daily water demand.
Fraunhofer ISE streamlines use of epitaxial wafers in TOPCon solar cell manufacturing
Researchers at the German research institute have demonstrated that the so-called EpiWafers could be used directly for solar cell fabrication without needing a pre-gettering step. Their experiments provide a proof of principle* for epitaxially grown silicon wafers from German wafer manufacturer NexWafe GmbH.
