New research from Lappeenranta University of Technology shows that there is no single correct orientation for a PV installation.

The Northern Territory’s Desert Knowledge Australia Solar Centre will soon play host to a large-scale battery energy storage system which is expected to facilitate the transformation of the multi-technology solar testing facility into a local microgrid.

Scientists in China have developed a new recycling process for PV modules that can recover intact silicon cells from end-of-life products, and process them back into wafers. As part of the recycling process, the wafers are purified and surface-treated, making them suitable for integration into new, high-efficiency cells and modules.

A research group led by UNSW’s Professor Martin Green has published Version 60 of the Solar cell efficiency tables.

Western Australian developer Frontier Energy, a relatively new player in the renewable space, says preliminary findings from its green hydrogen study indicate it could be producing “significantly earlier than originally anticipated” from its Bristol Springs Solar Project, to be located south of Perth.

UK scientists have compared the performance of lithium-ion storage systems and vanadium redox flow batteries for a modeled 636 kW commercial PV system in southern California. They have found that both technologies, coupled with an oversized PV array, could achieve a levelised cost of electricity of less than US$0.22/kWh (AU$0.32/kWh), while offering a self-sufficiency ratio of 0.95.

With some of the highest rooftop solar PV penetration in Australia the outback town of Alice Springs will soon play host to the Northern Territory’s first resident Virtual Power Plant with the project partners exploring how best to bolster the reliability of the local grid and pave the way for the increased penetration of renewable energy.

United States-based data company Global Energy Monitor has launched a new open-source tool that lists Australia’s large-scale solar plants alongside those from another 147 countries.

German scientists have conducted a series of experiments on gallium-doped silicon solar cells to understand the causes of degradation in PV cells and modules treated with gallium rather than boron. They confirmed that the performance losses are caused by a bulk defect in the material, and found that the right combination of light and temperature can “heal” earlier damage and even lead to small improvements in overall cell efficiency.

Scientists in the United States have fabricated a triple-junction solar cell that reached 39.5% efficiency – a world record for any type of cell under one-sun illumination. Though relying on materials and processes that are still too costly for most commercial uses, the concept could soon see actual applications in powering satellites and other space-bound technology.
