Tests conducted by a research team in outdoor environments in Spain and Poland have demonstrated a strong correlation between perovskite solar cell degradation and the combined effects of climatic and operating conditions. The scientists found that open-circuit operation accelerates degradation, whereas operation at the maximum power point and under short-circuit conditions has a lower impact.

Solitek has launched full-black 425 W bifacial solar modules with matte, satin-textured glass for glare-sensitive sites such as airports, road barriers, and buildings.

Scientists in Czechia have proposed to use parallel inverters in PV systems to not only reduce instability, but also to increase power yield. The proposed approach reportedly results in higher maximum power point tracking (MPPT) performance.

Human Geographer Thilo Wiertz speaks to pv magazine on the particular features that characterised the trajectory of renewable energies after the outbreak of the war in Ukraine. He emphasised how the geopolitical tensions arising from this conflict have reshaped the political debate about the energy transition, with the energy security perspective gaining in importance.

Australian energy storage startup Green Gravity will explore opportunities to deploy its gravitational energy storage technology in Europe after inking an agreement with the Romanian state-owned energy company Complexul Energetic Valea Jiului SA.

New research from Serbia claims air-polluted urban climatic conditions may not only induce maximum power point (MPP) tracking problems in PV systems but also reduce power yield by up to 30%. The scientists also said that soiling may significantly affect the functionality of single-stage inverters operating in grid-forming mode.

Scientists have used the US National Renewable Energy Laboratory’s (NREL) HOMER software to calculate the degradation of solar panels deployed in two rooftop PV systems operating in Germany since 2003. Their calculations focused on the energy productivity of the systems.

Hungarian company SolServices has published a white paper outlining ways to make solar farms more compatible with nature and wildlife, from insects and amphibians to birds, bats, rodents and big game.

Russian researchers have transmuted poisonous Sosnowsky’s hogweed into high-grade anode material for sodium-ion batteries. The obtained material has a Coulombic efficiency of 87%, which is on par with the best reported results for hard carbons synthesised from other raw materials.

Ukraine is still facing dire circumstances, with war continuing to claim lives and Russian invaders occupying large parts of the country. Solar plant owners also face serious challenges, including collateral damage, looting, destruction of communication infrastructure, and payment shortfalls. However, a bold vision for recovery has been set out with a key role for solar, as Ian Skarytovsky reports.
