Perovskite-silicon tandem single-cell solar module with 26.2% efficiency
Researchers in Saudi Arabia claim to have reduced cell-to-module losses in tandem perovskite silicon photovoltaic devices through an optical redesign of the module through refractive-index engineering. They built a monolithic perovskite-silicon tandem mini-module with a power conversion efficiency of 26.2%.
Solarspace launches 555 W half-cut solar module with gallium-doped cells
The new module has a power conversion efficiency of up to 21.5% and a temperature coefficient of -0.35% per C.
EV shipping is set to blow internal combustion engines out of the water
Modeling 5 to 10 GWh electrified containerships, researchers find that 40% of routes today could be electrified in an economically viable manner, before considering environmental costs.
Artifical intelligence model to forecast entire region’s solar output using real-time satellite data
Combining satellite images of Australian rooftops with those of real-time cloud cover to create accurate forecasts of distributed solar output for suburbs and perhaps even whole regions and states is the focus of a new Australian startup, Solstice AI.
Pumped hydro storage project moves forward in Faroe Islands
SEV, the utility for the Faroe Islands, has secured funds from Nordic Investment Bank to build a pumped hydro storage facility on the island of Streymoy. The Mýruverkið II project, valued at DKK 1.3 billion ($174 million), is set to go online in the 2027-28 period.
The Hydrogen Stream: Dye-sensitized photocatalyst promises most efficient solar water splitting to date
Japanese researchers have developed a new way to improve water splitting, while South Korea has completed its largest hydrogen production complex. Scotland and England have announced new hydrogen investments, and Uzbekistan and Saudi Arabia’s ACWA Power have agreed to collaborate on hydrogen projects.
Cubical luminescent solar concentrator devices in urban environments
An international group of researchers has developed a cubical luminescent solar concentrator (LSC) PV device that can be assembled in mosaic configurations for applications in urban environments. The best-performing device achieved a power conversion efficiency of 11.6%.
Solar-powered coffee bikes from Germany
Germany’s Liontron said it can prepare 300 cups of coffee per day from the PV modules and storage tech on its bicycles for beverage vendors. This means its mobile coffee shops can operate without grid connections.
New models to predict crop yields in agrivoltaics
A Swedish-Italian research group has applied state-of-the-art models for global horizontal irradiance decomposition to assess photosynthetically active radiation in agrivoltaic projects – an important variable to properly predict crop yield.
