AI tech for DC arc detection in PV systems
Scientists from China have developed a novel system that can detect DC arcs in PV installations through a back-propagation neural network. The novel technique reportedly ensures a detection time of less than 200 ms.
Radiative cooling tech for vertical solar panels
Developed by a US-Saudi research group, the novel technique employs two 45-degree inclined mirrors on the two sides of a PV module. On the back side, a spectral selective reflector enables the thermal radiation to be directed to the sky while preventing the back of a module from heating up by the scattered sunlight.
Sao Paulo inaugurates 7 MW floating solar plant
The government of Sao Paulo, Brazil, says that a new 7 MW floating solar project on a reservoir in the megalopolis is the first phase of a 75 MW facility that will be completed in 2025.
Perovskite-silicon tandem solar cell with sublimed C60 source material achieves 30.9% efficiency
The result was certified by Fraunhofer ISE CalLab. The cell uses a top inverted PV device using an electron transport layer made of thermally evaporated buckminsterfullerene (C60) with minimized parasitic optical absorption.
Australian consumers say bigger is better for rooftop solar
Solar panel and system prices are on the decline in Australia, but figures from industry analyst SunWiz show that a growing number of Australian households are opting to forgo savings in search of higher generation capacity.
Distributed US solar and storage policy trends
The NC Clean Energy Technology Center covers the latest trends in US solar policy.
Enel secures €560 million for 3 GW heterojunction panel factory in Italy
Enel has obtained €560 million ($610.2 million) for a solar module factory it is building in Catania, Sicily.
WoodMac predicts strong yet flat global PV growth through to 2032
Wood Mackenzie says the solar industry has reached a new stage in its evolution and is predicting around 350 GW of global solar installations annually for the next eight years. The research firm is also forecasting challenges for the solar manufacturing sector and long-awaited benefits from the Inflation Reduction Act in the United States.
All-perovskite triple-junction solar cell achieves 25.1% efficiency via new passivation technique
An international research team built the triple-junction device with dual bulk and interface passivation technique aimed at promoting halide homogeneity at the interface between the perovskite absorber and the hole-transport-layer. The 0.049 cm2 cell achieved a remarkable open-circuit voltage of 3.33 V and was also able to retain 80% of its initial efficiency after 200 h of continuous maximum power point tracking.
Trina Solar presents bifacial dual-glass TOPCon solar modules for rooftop PV
The Chinese manufacturer said its new TSM-NEG9RC.27 and TSM-NEG18R.28 combine n-type technology with 210mm rectangular silicon wafer (210R) cell technology. Their temperature coefficient is -0.29% per C and their efficiency can reach up to 22.3% and 22.7%, respectively.
