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.

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.

New research reopens the question around magnesium-based battery viability at room temperatures.

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.

Developed by an international research team, the cell features a cadmium sulfide electron transport layer produced using a novel ozone-doping strategy. This treatment enhances material purity and stability while widening the energy bandgap of cadmium sulfide.

Researchers in China have developed a dust monitoring technique that relies solely on the existing hardware resources of inverters, without requiring extra sensors or meteorological data. Tests on real rooftop PV arrays demonstrated an accuracy exceeding 96%.”

Researchers in Germany have examined how battery storage could help façade PV systems move beyond their niche market by 2030. Their findings show that a large majority of south-oriented façades in Europe could be equipped with vertical solar arrays combined with batteries.

Scientists in Spain have developed an amorphous-silicon solar cell that could be used in both transparent photovoltaics and tandem applications. The device reportedly achieves notable efficiency levels and may offer an alternative to transparent organic photovoltaics.

Researchers in California have created a new diagnostic metric that can reportedly predict if a battery can successfully power a specific task. The proposed model could be used in electric vehicles, unmanned aerial systems, and grid storage applications.

Researchers in China have built an off-grid rapid-cycling sorption-based atmospheric water harvesting system. Powered by three PV modules, the system was tested with four condensation methods indoor and outdoor.
