Arkansas Scientists Build Graphene-Based Solar Cells than Can Charge Supercapacitors

Graphene solar cells promise long-lasting self-powered sensor networks

Los Angeles CA (SPX) Nov 13, 2025 A team from the University of Arkansas and the University of Michigan has demonstrated the first use of temperature sensors powered exclusively by graphene-based solar cells, laying the groundwork for battery-free sensor systems. Using graphene's extraordinary energy-harvesting capability, these devices can capture power from their surroundings - including solar, thermal, acoustic, and kinetic s

Graphene-Based Solar Cells Used to Power Temperature Sensors

Researchers at the University of Arkansas and the University of Michigan have reported the first use of ultra-low power temperature sensors using graphene-based solar cells. The test is the first hurdle in developing autonomous sensor systems that draw power from multiple sources in the environment — solar, thermal, acoustic, kinetic, nonlinear and ambient radiation. The end goal is development of multi-modal sensors (incorporating more than one…
