Stanford scientists gain insight on polaron distortion in perovskite solar cells
Polaron formation in perovskite solar cells has been indicated in scientific research as a possible factor for making this kind of cell particularly efficient, although the mechanism behind polarons’ action is completely unknown. A U.S. research group has now observed how polaron distortions form and grow.
Sustainable pumped-hydro across 616,818 sites
Australian researchers have identified more than 600,000 sites suitable for closed-loop pumped-hydro energy storage projects across the globe. “Off-river” pumped-hydro is not only able to overcome the typical topographical issues of conventional pumped-hydro but is also cheaper.
Enhancing electron transfer kinetics crucial for viability of redox flow batteries
Scientists in the United States claim that further research is needed to gain a deeper understanding of kinetic stabilization strategies to increase cell voltage in redox flow batteries and bring them closer to commercial viability.
Assessing PV performance in zero-energy building
A Brazilian research team has shown the advantages of linking solar-powered zero-energy buildings to recharging stations for electric vehicles. It proposed a model that can be applied to any location.
New model to deploy cheaper PV at coal power plants
Researchers have assessed how much solar may be deployed on the rooftops and coal storage sheds in coal power plants in China and they have found potential for around 4 GW.
Artificial intelligence in photovoltaic production
Five scientific institutions in Germany are currently working together on self-learning production plants that use process data for the permanent optimization of manufacturing. The initiative is aimed at making the settlement of photovoltaic factories in Germany and Europe attractive again.
Power-to-X may cover 28% of global energy demand by 2050
The so-called powerfuels are primarily required for sectors that are difficult to electrify, such as aviation and shipping, as well as for the processing of raw materials. This is shown by a new study by Finland’s LUT University and the German Energy Agency.
Thermal model to predict PV panel temperature
Scientists in Turkey have tested a transient thermal model to predict PV module temperature during a five-day interval in June. The model considers the heat capacity of a PV module, which is usually not provided by manufacturers in their product sheets, as a parameter for temperature prediction.
Australian research improves scope, efficiency of PV light sensitizers
Australian scientists have developed an algorithm to increase both the efficiency and compatibility of light sensitizers in solar panels.
Oxford PV retakes tandem cell efficiency record
Perovskite developer Oxford PV has set a new world record for perovskite-silicon tandem cell efficiency at 29.52%, edging out the previous record set less than a year ago by Helmholtz Zentrum Berlin. The new record has been certified by the U.S. National Renewable Energy Laboratory.
