Outdoor testing identifies factors contributing to perovskite solar cell degradation
Tests conducted by a research team in outdoor environments in Spain and Poland have demonstrated a strong correlation between perovskite solar cell degradation and the combined effects of climatic and operating conditions. The scientists found that open-circuit operation accelerates degradation, whereas operation at the maximum power point and under short-circuit conditions has a lower impact.
Increasing PVT-assisted heat pump efficiency with liquid overfeed design
Researchers in China developed a large-scale PV-thermal heat pump system using a liquid overfeed method that reportedly improves both thermal and electrical efficiency. Field tests showed up to a 4.81% boost in power generation and significantly reduced pressure losses compared to conventional systems.
Bangladesh opens testing lab to certify solar module quality
The Bangladesh Standards and Testing Institution (BSTI) says its new solar module testing laboratory in Dhaka marks a major step toward enforcing quality standards and supporting the nation’s export ambitions.
Detecting PV module defects at a single glance
Scientists in China have developed a new deep learning model based on the so-called “You Only Look Once” algorithm, which requires only one forward propagation pass through the neural network to make predictions,
World’s first solar park featuring hydrogen-producing PV modules takes shape in Belgium
A 2 MW solar park in Wallonia, Belgium, will rely 50 kW of hydrogen-producing solar modules developed by Solhyd, a spin-off from KU Lueven. The installation will be the first demonstration of Solhyd’s technology at a commercially-relevant scale.
NTU achieves high stability in 25.1%-efficient inverted perovskite solar cell
Researchers at Nanyang Technological University have demonstrated a method to integrate chemically inert low-dimensional interface materials into the fabrication of inverted perovskite solar cells. Their prototype solar cells retained over 93% of the initial power conversion efficiency of 25.1% after 1,000 hours of operation, and 98% after 1,100 hours at 85 C.
Fraunhofer ISE spin-off launches heat pump information platform
Heat Pumps Watch will work to change consumer attitudes towards heat pump adoption by delivering evidence-based information on the technology aimed at professionals, policymakers and homeowners.
Fothermo debuts immersion heater for excess PV power
The German company said its new device features a DC input supporting up to 3 kW of photovoltaic power. The heating output can be continuously adjusted between 0 W and 1,000 W. Priced at €549 ($635) including VAT, the heating element is designed for hot water storage tanks with capacities of up to 500 L.
AI powered solar forecasting helps UK grid operator reduce balancing costs
Open Climate Fix says its Quartz Solar tool saves Great Britain’s grid operator GBP 30 million ($39 million) per year through more accurate forecasting, which reduces the reserve capacity needed for balancing the electricity system. The non-profit company has used machine learning techniques with satellite, weather and historical generation data to reduce forecasting errors by half.
