Researchers at University of New South Wales (UNSW) have revealed a novel solar-panel technology that could dramatically increase electricity production — potentially doubling the output over conventional silicon panels.
The breakthrough centers on a process called Singlet fission. In this method, a single photon of sunlight can produce two packets of usable energy, instead of the usual one. By applying a thin organic-molecule layer (compatible with existing silicon-panel designs), the researchers showed that the electric output can be significantly increased — without the need for costly new manufacturing processes.
Current commercial solar panels typically convert around 20–25 % of sunlight into electricity. With singlet fission, the theoretical efficiency limit could jump close to 45 %, more than doubling effective power from the same sunlight.
If successfully scaled, this innovation could pave the way for cheaper and more powerful solar installations — making renewable energy more accessible, especially in regions with limited space or high energy demand.
