The briefing
A University of Groningen-led team outlines a method to retain heat and harvest energy from hot electrons far longer than usual, potentially easing the Shockley–Queisser limit of about 33% for solar cells. The concept remains early-stage and would require further validation and engineering before any commercial impact.
