Fighting coastal corrosion
Salt in the air can wreak havoc with projects that lack the necessary corrosion resistance, proving costly for asset owners or the engineering, procurement and construction (EPC) companies that built them. Alexander Gebert, sales director at Tobsteel, argues that quality stainless steel fasteners can save costs for solar investors and engineering, procurement and construction (EPC) contractors in the long run.

Longi, Soochow University unveil 34.0% perovskite-silicon tandem solar cell based on dual-anchored interfacial design
Soochow University and Longi researchers developed a ZrOâ‚‚ interfacial strategy that reduces recombination and leakage while improving charge extraction in perovskite-silicon tandem solar cells. The resulting device achieved 2.014 V open-circuit voltage and retained 84% of its initial efficiency after 2,000 hours.
