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.
New battery for residential, commercial applications
Dutch manufacturer MG Energy Systems is offering a new storage system in two versions, with capacities of 5.8 kWh and 7.2 kWh and nominal capacities of 230 Ah and 280 Ah.
Larsen & Toubro builds green hydrogen plant in India
Larsen & Toubro, a Mumbai-based engineering group, has commissioned 380 kW of an 800 kW green hydrogen plant for self-consumption at its Hazira manufacturing complex in Gujarat, India.
The mobility rEVolution: New tech cuts risk of electrocution from EVs
UK researchers have found a way to reduce the risk of electrocution with electric vehicles, while US utility Duke Energy said it is exploring how the Ford F-150 Lightning can serve as a grid resource. Chinese carmaker Geely posted disappointing first-half results, while IHS Markit said it expects strong uptake of battery electric vehicles in Europe through to 2030.
Controlling the crystals for a 17.96% efficient perovskite solar cell
Scientists in Taiwan demonstrated a new way to produce high-purity lead-iodide, as a precursor material for a perovskite solar cell. By using temperature to better control the orientation of crystals, the group was able to show much higher efficiencies when the precursor was used to fabricate a perovskite layer and subsequently a working solar cell.
Rooftop PV for pre-cooling of residential, commercial buildings
Australian researchers have developed a way to use rooftop PV to run air conditioners to pre-cool residential and commercial buildings. They have identified several factors that could help reduce a building’s energy costs.
TotalEnergies, InVivo switch on vertical agrivoltaic system in France
TotalEnergies said its new 111 kW pilot facility in France will show the impact of solar panels on agricultural yield, while also shedding light on biodiversity, carbon storage, and water quality.
PV with gravity storage, redox flow batteries in buildings
Indian researchers have developed a new hybrid system featuring a conventional rooftop PV system, a solar tree, two gravity power modules for building (GPMBs), and a vanadium redox flow battery (VRFB), with power exclusively provided by the two solar installations.
