Scientists uncover quantum effect in organic material for efficient solar power
በAI የተዘገበ
Researchers at the University of Cambridge have discovered a quantum phenomenon in an organic semiconductor, enabling highly efficient light-to-electricity conversion. This breakthrough, involving Mott-Hubbard behavior in the molecule P3TTM, could lead to simpler, cheaper solar panels made from a single material. The finding connects to foundational physics from a century ago and marks the 120th anniversary of physicist Sir Nevill Mott's birth.
Solar power accelerates toward global dominance
Solar electricity generation doubled between 2022 and 2024, now supplying 7 percent of the world's electricity. In the first half of 2025, wind and solar surpassed coal as the top source of power, driven largely by solar's rapid growth. Experts predict solar could generate 80 percent of global electricity by 2100.
