Researchers at Fraunhofer ISE have developed new imaging methods to measure losses in individual sub-cells of multi-junction solar cells, specifically perovskite-silicon tandem and perovskite-perovskite-silicon triple junction devices. The research team detailed the Suns-Voc and Suns-PL imaging methods for tandem cells, and used a combination of luminescence imaging and lock-in thermography for triple-junction cells. These methods provide insights into electric losses, selectivity losses, and resistive losses, making them valuable for quality assurance in production and research settings. Additionally, the effectiveness of these imaging techniques in analyzing the quality of electron and hole transport layers in solar cells is demonstrated, with the potential for application in other tandem and triple junction cell technologies, including III-V compound solar cells for space applications.

Solar, wind and storage: stable prices, stable grid
Australia's rapid expansion of solar and wind energy has not increased wholesale electricity prices since 2016, making it a global renewable energy leader. Solar and wind are displacing coal and gas, meeting all growth in demand, with stable grid infrastructure and high rooftop solar adoption rates contributing to falling wholesale prices. Rooftop solar systems in Australia cost $6,000 and last 20 years, with an annual electricity output of 1200-1400 kWh per kW, driving widespread adoption at a low cost of 3 US-cents per kWh. All-electric solar homes in Australia have zero gas and petrol bills, with large energy storage options available, and the quick installation and high resilience of Australian rooftop solar systems make them a promising solution for climate experts.

Grid operators, ratepayers shouldn’t fear flexible data centers: GridCARE
GridCARE, a California-based startup, released an analysis showing that large data centers can help reduce electricity costs and improve grid reliability by incorporating flexibility into their operations. By partnering with utilities and using artificial intelligence in load management, data centers can potentially reduce costs by 5% across all customer classes or unlock over $1.35 billion in capital for the utility. Another analysis by Camus Energy, encoord, and Princeton University found that flexible data centers could connect to the grid sooner and eliminate incremental power supply costs, contributing $733 million per gigawatt towards the cost of its incremental load. Overall, these studies suggest that data centers can play a key role in improving grid efficiency and sustainability, leading to lower rates for customers and accelerating investment in grid assets.
