Solar energy modeled as digital twin in Unreal Engine video game software
An international research team has created a digital twin that purportedly enables analysis of different scenarios on PV plants’ aerial monitoring. The new tool is claimed to reduce the risk associated with real-world experimentation and help identify the most effective strategies to improve PV system monitoring.
Argonne Lab unveils technique to track battery aging in real time
Argonne Lab uses magnetic resonance to track chemical changes inside working lithium battery cells. without destroying the test cells.
Solar-electric vehicle requires no charging for daily use
California-based solar electric vehicle maker Aptera Motors demonstrated its first production-intent design vehicle. It said the vehicle will offer up to 40 miles of range daily from its onboard solar cells.
Solid-state batteries enter pilot production, costs expected to drastically drop
The latest findings from Taipei-based intelligence provider TrendForce show that all-solid-state battery production volumes could have GWh levels by 2027. The rapid expansion will lead to cell price declines, reaching CNY 0.6-0.7/Wh ($0,084-$0,098) level by 2035.

Longi Green Energy sets world record for solar module efficiency at 25.4%
China’s Longi Green Energy has set a new world record for crystalline silicon solar module efficiency with its independently developed hybrid passivated back contact (HPBC) 2.0 module, achieving a conversion efficiency of 25.4%, according to a certification report from Germany’s Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE).
Sunrise brief: Solar panels: Larger, thinner… and weaker?

Positive early results from first test of perovskite tandem solar cells in space
The perovskite-silicon and thin-film tandem solar cells were developed by Helmholtz-Zentrum Berlin and placed on an OOV-Cube small satellite to test their reactions to high levels of radiation—and whether “soft” perovskite solar cells can heal after taking on radiation damage.
Solving the UV problem of n-type solar
Laboratory testing has revealed that some negatively-doped, “n-type” tunnel oxide passivated contact (TOPCon) and heterojunction (HJT) solar modules are susceptible to ultraviolet (UV) light-related damage and degradation. That could mean trouble down the line, if modules in the field begin to show UV-related performance loss. Manufacturers are implementing solutions at cell and module level.
Powering restaurants with rooftop PV, reversible fuel cells
Researchers have simulated the operation of bifacial PV and proton exchange membrane reversible fuel cells across restaurants in five different U.S. states. Taking into account varying rates of bifacial PV’s rearside gains, they found that LCOE was as low as $0.029 per kWh.
