Nanoscale Device Boosts Energy Efficiency
Researchers at UNSW Sydney have made a significant breakthrough by developing a nanoscale device that converts wasted infrared light into usable energy. This technology, unveiled on 18th May 2026, has the potential to enhance solar panels and manufacturing systems.
The research, published in Nature Photonics, tackles the challenge of energy loss in photonics by converting low-energy infrared and red light into higher-energy visible light. Achieving a photon conversion efficiency of 8.2%, this device is among the most efficient of its kind.
Study lead author Dr Thilini Ishwara from UNSW stated, “This work demonstrates a big step forward. Achieving high efficiencies in films is difficult in these ultrathin molecular systems – good light absorption is needed and energy loss needs to be minimised.”
Applications Across Industries
The innovative device could transform industries by recovering or reusing wasted infrared light. For example, in solar energy systems, converting low-energy light into visible wavelengths could significantly improve performance.
According to the researchers, the technology has implications for infrared sensing, photocatalysis, and optical communications. It could also advance next-generation additive manufacturing technologies, such as volumetric 3D printing.
Importantly, the device operates in a solid-state structure compatible with semiconductor-style manufacturing, increasing its commercial viability compared to older liquid-based approaches. This compatibility makes it more practical for widespread use.
Dr Ishwara expressed enthusiasm for commercializing the technology, noting its potential applications in tumour treatment with deeper tissue penetration, affordable water purification, night vision, and 3D printing. “We are keen to commercialise our technology,” she said.
The research could have a wide-ranging impact, particularly in industries looking to harness and utilise light energy more efficiently. As a result, this advancement marks a promising step forward in the fields of energy conversion and photonics.
UNSW’s development addresses the longstanding problem of energy loss in photonics, offering a solution that could lead to significant improvements in various technologies. With a focus on commercializing the technology, UNSW aims to bring these innovations to market, benefiting multiple sectors.
