New research sheds light on voltage deficit in selenium solar cells
An international research team has investigated the impact of intrinsic point defects in selenium solar cells and has concluded that these defects are not responsible for voltage deficit. The scientists rather believe interfaces and extended defects may be the cause of this well-known issue for this kind of PV device.
New approach to measure rear plane-of-array irradiance in bifacial PV plants
Researchers in Denmark claim to have identified the best locations for rear plane-of-array irradiance sensors on the back of single-axis trackers in bifacial PV projects. Their work suggests how to reduce sensor quantities while maintaining accurate performance monitoring.
Denoising outdoor electroluminescence images of PV panels through deep learning
Researchers in Australia have developed a simplified residual network-based architecture method to filter out noise from electroluminescence images of PV modules. The proposed technique reportedly enhance the accuracy and efficiency of automated inspection systems for utility-scale PV plants.
Danish energy sector probes removes concerns about solar involvement
A Danish trade group has ruled out any link between suspicious components found in local energy equipment and recent reports of compromised solar inverters in the United States, narrowing the scope of an ongoing cybersecurity investigation.
Solar to power Denmark’s largest energy community
Denmark’s largest energy community is now under construction, featuring more than 30,000 sqm of solar rooftops with a total capacity of about 4 MW. The project will use building-integrated photovoltaics (BIPV) on pitched roofs and building-attached photovoltaics (BAPV) on flat roofs from Danish specialist Solartag.
SolarPower Europe calls for tough cyber rules following Danish import probe
The recent discovery of unexplained components in Danish energy equipment highlights the urgent need for stronger EU solar cybersecurity rules, according to SolarPower Europe.
The Hydrogen Stream: Axpo reports progress on automated H2 project
Axpo has started remotely controlling a 2.5 MW hydrogen production facility (HPF) in Switzerland, while Statkraft says it will halt new green hydrogen projects amid market uncertainty.
Danish startup launches solar tile for pitched roofs
Solartag has developed a 71 W solar tile with a weight 14.2 kg/m² and a power conversion efficiency of 16%. The new product relies on black PERC cells and is standardized for mass production, according to the manufacturer.
New research sheds light on intrinsic limitations of selenium solar cells
Danish researchers have analyzed fundamental material properties of selenium solar cells and have found their potential is higher than generally believed. They used carrier-resolved photo-Hall analysis to address discrepancies and reproduce experimental current-voltage and external quantum efficiency measurements.
