Temperature coefficient of short circuit current may not be proper metric for perovskite-silicon tandem solar cells
Researchers in Saudi Arabia have conducted a series of tests to investigate the temperature coefficient of the short circuit current in perovskite-silicon tandem solar cells and have found that it may not be considered a proper metric to assess these devices’ performance and behavior.
Spotlight on TOPCon: PI Berlin shares concerns about degradation
Asier Ukar, the director of PI Berlin Spain, discusses the importance of addressing the risks associated with tunnel oxide passivated contact (TOPCon) tech early on, even though it outperforms (passivated emitter rear contact (PERC) when considering standard and tangible indicators.
Bslbatt unveils 100-mm batteries for rooftop solar
China’s Bslbatt says its new batteries have 10.24 kWh of storage capacity and a nominal voltage of 51.2 V. It measures 700 mm x 980 mm and is 100 mm thick.
Inside the impacts of soiling
Scientists in India carried out a comprehensive study into the impacts of soiling on PV modules – measuring the amount of performance loss caused by different types of dust and bird droppings, and for modules installed at various tilt angles, in the hot-dry climate of Vellore in southern India. Their findings could allow developers to better take into account and mitigate the effects of soiling during site selection and system design.
Solar-plus-storage microgrids minimize power shutoffs during wildfires
Lawrence Berkeley National Laboratory researchers have shown that microgrids equipped with solar-plus-storage systems can maintain an average levelized cost of energy (LCOE) below $0.30/kWh and limit annual public safety power shutoffs to 2% to 3% of annual energy demand.
