Scientists demonstrated two new approaches to improving the stability of perovskite solar cells. By both incorporating rubidium into the structure of the perovskite, and adding a film of two-dimensional perovskite as a capping layer, they were able to demonstrate a significant reduction in the cell’s sensitivity to moisture. The group says its research will open up new routes to improved performance and stability in perovskite PV.

New research from Australia has shown that vortex generators and glass texturing have so far proved to be the most effective solutions among the novel methods explored for lowering the temperature of solar panels.

According to new research from the U.K., solar parks may help maintain natural habitats for pollinators that could be, otherwise, destroyed by intensive farming. The study also highlights that biodiversity could be both positively and negatively affected by solar parks and associated land-use change.

A newly published report looks at the impact of solar projects on biodiversity. It shows that the environmental consequences of solar tend to vary, depending on species and location.

French train manufacturer Alstom said that its Coradia iLint train is now ready for commercial deployment and the Chilean government launched a call for green hydrogen projects. Furthermore, several developments for fuel cell electric vehicles were announced.

The cell, which looks externally like a device with a two-terminal architecture, was built with III-V semiconductor layers that were connected to the silicon sub-cell on the atomic level. The cell may be used in electrically powered aircraft and drones.

The new panel has a nominal power of 395 W and a claimed temperature coefficient of 0.28% degrees Celsius.

The Dutch association of national-regional electricity and gas network operators, Netbeheer Nederland, is leading a plan to deploy up to 2 million hybrid heat pumps by 2030. The plan should be supported by a subsidy scheme by the government and enable the installation of at least 100,000 heat pumps per year from 2024.

Australia’s Renascor Resources has confirmed it has raised AUD 15 million ($11.6 million) to fund its Siviour battery anode material project up to the construction phase. The project will be the world’s first integrated mine and purified spherical graphite operation outside of China.

A solar racking system’s strength is determined in part by the metal racking, but it also depends on the roof’s underlying structure. Rafters and any supporting structures must be strong enough to withstand your region’s maximum wind and snow loads.
