Abstract

There is described a cascade-type compact hybrid energy cell (CHEC) that is capable of individually and concurrently harvesting solar, strain and thermal energies. The cell comprises an n-p homojunction nanowire (NW)-based piezoelectric nanogenerator and a nanocrystalline/amorphous-Si:H single junction cell. Under optical illumination of ˜10 mW/cmand mechanical vibration of 3 m/sat 3 Hz frequency, the output current and voltage from a single 1.0 cm-sized CHEC was found to be 280 μA and 3.0 V, respectively—this is are sufficient to drive low-power commercial electronics. Six such CHECs connected in series were found to generate enough electrical power to light emitting diodes or drive a wireless strain gauge sensor node.
