SHJ Solar Modules Break Efficiency Records with 25.44% Certified Performance

Researchers have developed silicon heterojunction solar modules that achieved certified 25.44% efficiency at Fraunhofer ISE. The breakthrough represents significant progress toward the theoretical 29.4% efficiency limit for silicon solar cells while demonstrating exceptional 98.6% cell-to-module performance ratios that challenge competing technologies.

Record-Breaking Solar Performance

Solar technology has taken another significant leap forward with reports of silicon heterojunction (SHJ) modules achieving certified 25.44% efficiency at Fraunhofer ISE. According to the analysis published in Nature Communications, this performance surpasses the previous large-area module record of 24.9% set by Maxeon earlier this year and edges past LONGi’s 25.4% benchmark from July 2024.

Laser-Synthesized Gold Nanoparticles Boost Raman Spectroscopy Sensitivity, Study Finds

Scientists have pioneered a dual-wavelength laser approach for creating gold nanoparticles that dramatically enhance Raman spectroscopy signals. The optimized nanoparticles demonstrate up to 1840-fold signal enhancement, enabling detection of previously undetectable chemical traces.

Breakthrough in Nanoparticle Fabrication

Researchers have developed an innovative laser-based method for creating gold nanoparticles that significantly enhances surface-enhanced Raman spectroscopy (SERS) capabilities, according to a recent study published in Scientific Reports. The technique utilizes dual-wavelength processing from Nd:YAG lasers to produce optimized nanostructures that amplify Raman signals by several orders of magnitude, potentially revolutionizing chemical detection and analysis.
