U.S. scientists build graphene-based solar cells than can charge supercapacitors

The solar cells combine multilayer graphene with silicon wafers, harvesting both solar and kinetic energy for continuous operation. Tests show the cells can autonomously power supercapacitors embedded in a temperature sensor.Researchers from the University of Arkansas in the United States have fabricated a graphene-based solar cell that can be used in Internet of Things (IoT) applications. The device was developed in the frame of a research project intended to develop autonomous sensor systems that draw power from multiple sources in the environment, including solar, thermal, acoustic, kinetic, ...
