Scientists ‘draw’ crystals with gold using single laser pulse for better solar panels

SMRTR summary

Michigan State University researchers developed a breakthrough method to precisely control crystal growth by hitting gold nanoparticles with a single laser pulse. This technique allows scientists to "draw" crystals at exact locations and times, solving the longstanding problem of unpredictable crystal formation. The method could significantly improve solar panels, LED lighting, and medical imaging devices that require high-quality crystals positioned precisely for optimal performance.
