The researchers that created the atlas considered mining pits, pit lakes and tailings ponds within mining sites and located nearby reservoirs. The selected sites have a potential storage capacity of 30 TWh.

Energy Vault has begun construction on a 293 MWh green hydrogen and battery storage facility within utility Pacific Gas & Electric’s service territory in northern California.

The German research institute is investigating the use of commercially available vacuum-based evaporation equipment to manufacture perovskite thin films and contacts layers in the fabrication of perovskite-silicon tandem cells.

TrinaTracker, a division of China’s Trina Solar, says its new Vanguard 1P tracker system has a maximum length of 140 meters and can be equipped with N-type modules.

Developed by researchers at the Korea Institute of Energy Research (KIER), the novel cell was conceived for applications in bifacial perovskite-silicon tandem PV devices. The academics claim they were able to overcome an intrinsic dopant-induced internal degradation mechanism which leads to undesired lithium-ion diffusion that would have been detrimental to the cell efficiency.

Prosolarbirds has designed a harmless device to prevent birds from perching on the panels and soiling them with excrement. It is a rotating device, without a motor, that is activated by a slight breeze, and whose movement prevents birds from landing.

The European Union has secured a critical raw materials deal with Rwanda, expanding collaboration between the two sides – particularly in the solar sector. A friendly regulatory environment deserves credit for helping to fast-track the adoption of solar, according to local analysts.

Engineers in Spain have developed a PV system solution that uses steel cables as a mounting structure. They say it is deployable in different scenarios with limited space.

Waaree says its FLW series of flexible, lightweight solar panels can be seamlessly integrated into a diverse range of environments. It claims that they are ideal for applications in which traditional, rigid panels could pose challenges.

Indian researchers have proposed to build tandem solar cells based on a CIGS top cell and a bottom cell relying on a single-walled carbon nanotube (SWCNT) absorber. SWCNTs were previously used in solar research as an alternative to conventional metal grid contacts or hole transport layers (HTLs), as they combine optoelectronic properties, flexibility, chemical stability, and simple transfer protocols.
