Supermarket EV chargers in Berlin could improve efficiency by over 250%
German researchers say shared-use and digital brokerage models could lift utilization and profitability of supermarket EV charging stations by up to 255%.
Cadmium telluride vs. crystalline silicon in agrivoltaics
Canadian researchers investigated how the transparency of cadmium telluride and crystalline silicon solar panels affects lettuce growth in agrivoltaic systems. They found that 69%–transparent silicon panels increased lettuce yield by 3.6%, whereas cadmium telluride panels led to a reduction in yield.
Novel swapping technique for partially shaded PV systems
Researchers in India have developed an algorithm for quadrant swapping in PV arrays, enabling the creation of new quadrants containing either shaded or unshaded modules. The method was tested across ten shading scenarios with varying irradiation levels and demonstrated “superior” performance compared to conventional approaches.
Sofab Inks achieves 22.2% efficiency in mini inverted perovskite solar panel
The U.S. startup said the 30 x 30 cm perovskite solar cell device featured its tin oxide electron transport material produced in a sheet-to-sheet slot die coating process.
High-rise buildings could soon use gravity energy storage, say researchers
Researchers in Canada have proposed using gravity-based energy storage in high-rise buildings, in combination with photovoltaic facades, small wind turbines, and lithium-ion batteries. Their modeling indicated that this hybrid system could achieve a levelized cost of energy ranging from $0.051/kWh to $0.111/kWh.
Floating photovoltaics based on spiderweb design
Scientists in the United Kingdom have developed a new web-inspired concept for floating PV farms, modeled after spider webs. The system is said to be particularly suitable for spiral and radial configurations, as well as for deployment between offshore wind farms.
ArcelorMittal starts BIPV module production in France
ArcelorMittal has started producing its Helioroof building-integrated PV modules in France. The steelmaker says the system aims to simplify energy retrofits for commercial and industrial roofs.
Prototype magnesium battery operates at room temperature in breakthrough
New research reopens the question around magnesium-based battery viability at room temperatures.
Market trust key for perovskite solar commercialization
In a new perspective paper, researchers from Dresden University of Technology and Denmark’s InfinityPV analyzed scientific research and more than 100 companies involved in organic PV and perovskite solar cell manufacturing. Their findings show that the commercialization of these technologies depends on the PV industry’s ability to increase financial transparency.
Solis unveils 75–125 kW hybrid inverter for C&I solar
The Chinese manufacturer said its new inverters can deliver 160% overload for 200 ms in off-grid mode, ensuring stable startup of heavy loads. The IP66-rated products feature a maximum efficiency of 97.6% and a European efficiency of 97.2%.
