## Description

- description: Energy harvesting is essential for the internet-of-things networks
    where a tremendous number of sensors require power. Thermoelectric generators
    (TEGs), especially those based on silicon (Si), are a promising source of clean
    and sustainable energy for these sensors.  However, the reported performance of
    Si TEGs never exceeded power factors of 0.1 μW〖cm〗^(-2) K^(-2) due to the poor
    thermoelectric performance of Si and the suboptimal design of the devices. Here,
    we report a planar-type Si TEG with a power factor of 1.3 μW〖cm〗^(-2) K^(-2).
    The increase in thermoelectric performance of Si by nanostructuring based on the
    phonon-glass electron-crystal concept and optimized three-dimensional heat-guiding
    structures resulted in a significant power factor. In-field testing demonstrated
    that our Si TEG functions as a 100-W-class harvester. This result is an essential
    step toward energy harvesting with a low-environmental load and cost-effective
    material with high throughput, a necessary condition for energy-autonomous sensor
    nodes for the trillion sensors universe.
