UNSW researchers boosted TOPCon solar cell efficiency by locally thinning the rear poly-Si layer, reducing parasitic absorption while preserving wafer integrity. The champion cell built with this ...

The Chinese manufacturer unveiled its new TOPCon bifacial TNC3.0 module at WFES 2025. The 1,500 V, IP68-rated panel offers over 85% bifaciality, a 0.26%/C temperature coefficient, and a 30-year ...

The fully automatic, 18-volt DW077 rotary laser is accurate to 1/8 inch per 100 feet. The self-leveling laser features an out-of-level shut-off. Its beam is visible indoors up to 100 feet from the ...

California machine shop quadrupled output by switching from manual TIG to robotic laser welding, eliminating skilled labor ...

Semiconductor lasers use the optical properties of semiconducting materials to produce coherent light. Electrons and their positive-charge counterpart called holes are injected into an optically ...
