TOPCon shingle solar cell achieves 22.0% efficiency via thermal laser separation
Scientists from Germany’s Fraunhofer ISE and US panel maker Solaria have applied thermal laser separation and post-metallization passivated edge technology to tunnel oxide passivated contact (TOPCon) cell production. They have developed shingle PV devices that are more efficient than cells built with conventional laser scribing and mechanical cleaving methods.

Perovskite alkylammonium chloride solar cell achieves 26.08% efficiency
The US National Renewable Energy Laboratory (NREL) has certified that a South Korean research team has achieved a 25.73% efficiency rating with a perovskite PV cell based on alkylammonium chlorides. The champion device built by the scientists reached an efficiency of 26.08%.
Plastic strip to prevent birds from nesting under rooftop solar
Netherlands-based BirdBlocker has developed a plastic strip that can be placed under solar panels installed on pitched rooftops. The long needles prevent birds from nesting under the modules. The structure is attached to the frame of the modules with stainless steel clips.
New thermal battery offers fast, efficient performance at low cost
US engineers have built a scalable thermal energy storage prototype system that combines the best latent and sensible heat transfers. The technology, which is now market-ready after three years of testing, consists of engineered cementitious materials and thermosiphons in a combination that enables fast, efficient thermal performance at low cost.
