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.

Crystal Orientation Breakthrough Enables Low-Pressure Solid-State Battery Operation

Scientists have demonstrated that controlling cathode crystal orientation can eliminate destructive stress in solid-state batteries. This breakthrough allows lithium metal batteries to operate at pressures below 5 MPa, addressing a major commercialization barrier.

Crystal Engineering Unlocks Low-Pressure Solid-State Battery Performance

Researchers have made a significant advancement in solid-state battery technology by demonstrating how cathode crystal orientation controls mechanical stress generation during operation. According to reports published in Nature Communications, this discovery enables lithium metal solid-state batteries to function effectively at stack pressures below 5 megapascals – dramatically lower than the 60+ MPa typically required.
