The Silicon Era Is Fading — The Moment Perovskite Solar Cells Hit 34%, the Energy Game Changed Forever
For half a century, solar efficiency was stuck at the 25% wall. Now perovskite-silicon tandem cells have shattered that barrier with an astonishing 34.85% efficiency record, marking the most significant leap in photovoltaic technology since the 1950s. The real question is whether this stays a lab curiosity or actually makes it onto your rooftop.
