Scientists in Japan have fabricated an inverted pervoskite cell with a new bond/charge regulated defect passivation technique consisting of introducing bifunctional molecules onto the perovskite absorber. The device exhibited a low open circuit voltage deficit and remarkable stability.

PV systems, surpassing minimum load demands in various regions, necessitate innovative grid integration measures. Active power management (APM), notably curtailment, emerges as a powerful solution here. By actively managing power peaks, PV systems can unlock new possibilities, contribute to grid stability, and enhance their overall value. The new IEA-PVPS Task 14 report encourages a shift in perspective, urging DSOs to explore the potential of APM instead of traditional grid expansion methods.

Scientists in Romania have found that extreme dust conditions may cause losses of 45.35% and 38.14% in maximum power and short-circuit current under outdoor conditions for different kinds of solar modules. They warned that, if the effects of climate change escalate, resulting in less rainfall and more frequent sandstorm events originating from the Saharan region, extreme scenarios are very likely to occur in Europe.

A group of researchers from the University of Lisboa and the Military Academy reported on the viability of agrivoltaics in Portugal. It found that spaced rows of PV modules combined with shadow-friendly crops had the most promising return and a payback period of less than five years.

In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.

Energy consultancy DNV has published a data validation and methodology review of solar irradiance data provider Solcast, a company it acquired early last year. The review found that the forecasting specialist’s figures are “at or above industry standards.”

Veolia plans to develop more than 40 solar projects on restored landfill sites in France amid dire shortage of suitable land for renewables development. The company expects the first plants to be operational by 2027.

A research team studied factors influencing floating PV efficiency and energy production and determined the optimal tilt and height to achieve lower cell temperatures compared with land-based PV.

The Philippines’ Department of Energy (DOE) is moving ahead with plans to require solar system installers to officially register with it. The DOE says that only registered installers will be recommended to government entities seeking PV installation services.

The PairTree off-grid solar charging system for electric vehicles (EVs) combines bifacial solar panels ranging from 4.6 kW to 5 kW, a 42.4 kWh capacity storage system, and one or two AC “Level 2” EV chargers.
