A groundbreaking hybrid material has been developed, offering the potential to revolutionize solar energy, medical imaging, and night vision technologies by efficiently converting low-energy light into higher energy light.
A collaborative team of scientists and engineers, including researchers from The University of Texas at Austin, has introduced a new class of materials capable of absorbing low-energy light and transforming it into higher energy light. This remarkable composite combines ultra-small silicon nanoparticles with organic molecules closely related to those utilized in OLED TVs. By facilitating the efficient movement of electrons between its organic and inorganic components, this novel material exhibits promising applications such as enhanced solar panels, more precise medical imaging, and superior night vision goggles.
The findings detailing this extraordinary material are presented in a recently published paper in Nature Chemistry, available as of June 12.
Sean Roberts, an associate professor of chemistry at UT Austin, remarked, “This process gives us a whole new way of designing materials. It allows us to take two extremely different substances, silicon and organic molecules, and bond them strongly enough to create not just a mixture, but an entirely new hybrid material with properties that are completely distinct from each of the two components.”
Composites are formed by combining two or more components, resulting in unique properties when they interact. For instance, carbon fiber and resin composites are renowned for their lightweight attributes, finding extensive use in airplane wings, racing cars, and various sporting goods. In the paper co-authored by Roberts, the combination of inorganic and organic elements displays remarkable interactions with light.
One noteworthy property is the material’s ability to convert long-wavelength photons, commonly found in red light and capable of traversing tissue, fog, and liquids, into short-wavelength blue or ultraviolet photons. These shorter-wavelength photons are instrumental in sensor functionality and driving a wide range of chemical reactions. Consequently, the composite material holds great promise for diverse technologies like bioimaging, light-based 3D printing, and light sensors that aid autonomous vehicles in navigating through fog.
Roberts further emphasized, “This concept may be able to create systems that can see in near-infrared. That can be useful for autonomous vehicles, sensors, and night vision systems.”
Moreover, the ability to convert low-energy light into higher energy levels could significantly enhance the efficiency of solar cells. By capturing near-infrared light that would typically pass through, solar panels can achieve heightened performance. Optimized implementation of this technology has the potential to reduce the size of solar panels by up to 30%.
The research team consists of scientists from the University of California Riverside, University of Colorado Boulder, University of Utah, and the aforementioned UT Austin. They have been actively exploring light conversion of this nature for several years. In a previous publication, they successfully connected anthracene—an organic molecule capable of emitting blue light—with silicon, a material commonly used in solar panels and semiconductors. To amplify the interaction between these materials, the team developed a novel method for establishing electrically conductive bridges between anthracene and silicon nanocrystals. This strong chemical bond significantly accelerates the exchange of energy between the two molecules, resulting in nearly double the efficiency of converting lower energy light to higher energy light compared to their previous breakthrough.
The research received funding from the National Science Foundation, The Welch Foundation, the W.M. Keck Foundation, and the Air Force Office of Scientific Research. Kefu Wang and Ming Lee Tang from the University of Utah, R. Peyton Cline and Joel D. Eaves from the University of Colorado Boulder, Joseph Schwan and Lorenzo Mangolini from the University of California Riverside, and Jacob M. Strain from UT Austin made substantial contributions to the research.
In summary, the development of this revolutionary hybrid material showcases its transformative potential in the realms of solar energy, medical imaging, and night vision technologies. By efficiently converting low-energy light into higher energy levels, this composite material paves the way for remarkable advancements in various applications, promising a brighter and more technologically advanced future.
