Researchers from Uppsala University have developed new indoor photovoltaic cells that have the potential to convert up to 34 percent of visible light into electricity to support a wide range of IoT sensors. The newly developed dye-sensitized photovoltaic cells consist of copper-complex electrolyte which is considered ideal for collecting indoor light from fluorescent lamps and LEDs. The new dye-sensitized solar cells transform indoor digital sensing for smart greenhouses, offices, shelves, packages, and other smart devices. Scientists believe such IoT devices self-powered by indoor solar cells can further enhance the next generation of robotics and autonomous systems currently in development.
