China’s DMEGC has released new solar panels with power conversion efficiencies of up to 21.2% and temperature coefficients of -0.33% per degree Celsius. They can be used with maximum system voltages of 1,000 V or 1,500 V.

French researchers have developed PV modules with an area of 11.6 square centimeters for indoor applications. They said the achieved efficiency level marks a world record for a flexible perovskite device larger than 10 square centimeters.

Spain recorded a 50% decrease in solar radiation due to bad weather in March – the biggest decline since the beginning of satellite records in 1994. By contrast, irradiation levels in Germany and the Balkans were 45% higher during the same period.

Japanese scientists have analyzed storage systems that combine PV and high-energy-density metal batteries. The rechargeable batteries have advantages such as low-charge voltage and high energy density, but stability and safety must be addressed before they reach commercial maturity.

The Regional Court of Apulia in Italy has ruled that the regional authorities must not deny permits to solar projects on agricultural land without considering how they combine electricity generation with crop cultivation and the raising of livestock. pv magazine spoke to Emilio Sani from law firm Sani Zangrando about the ruling’s potential consequences.

Municipal, regional and national authorities in France often have different views on permits for the deployment of solar. Marie Buchet, head of solar power at Syndicat des énergies renouvelables, spoke to pv magazine about four case studies. She said one-stop shops to unify all authorization processes could be the solution, as suggested by the European Union.

Approvals and planning procedures for solar parks are a major bottleneck for the energy transition. pv magazine recently spoke with a project developer about constraints and opportunities in Germany, ahead of the pv magazine Roundtables on June 28.

The main winner of the first renewables auction in the Philippines was developer Solar Philippines Nueva Ecija Corp. (SPNEC), which secured five solar projects, or 1.35 GW of capacity.

Emirates Global Aluminium (EGA) wants to produce silicon metal to create an integrated supply chain for the PV industry in the United Arab Emirates.

An international research group has assessed the potential of down-conversion materials to overcome the poor blue response of solar cells. They analyzed how such materials could be used to improve the performance of perovskite-based devices and found that certain advances might be achieved.
