Unlocking Solar Cell Efficiency with Magnetic Field Research

In a groundbreaking study recently published in Nature Chemistry, researchers have delved deep into the scientific understanding of singlet fission—a process where light particles split—and its intricate mechanisms.

Professor Tim Schmidt, the lead researcher from UNSW Sydney's School of Chemistry, has dedicated over a decade to studying singlet fission. He believes that this process holds the key to enhancing current silicon solar cell technologies.

"Traditional solar cells operate by absorbing photons, which are then directed to the electrodes to generate electricity," explains Prof. Schmidt. "However, a significant amount of light is lost as heat during this conversion process, leading to reduced efficiency in solar panels."

The majority of photovoltaic solar panels available today are constructed using silicon. Co-author Professor Ned Ekins-Daukes from UNSW's School of Photovoltaics & Renewable Energy Engineering points out that while silicon technology is cost-effective, it is approaching its limits in terms of performance.

"The efficiency of a solar panel is a crucial factor as it determines the proportion of solar energy that can be converted into usable electricity," Prof. Ekins-Daukes highlights.
