Our optical rectification diode is unlike anything currently in the market, or in the pipeline. It addresses unmet needs and has the potential to substantially increase efficiencies over existing devices. This technology for optical rectification has the potential of creating a new class of efficient energy conversion devices.
Current semiconductor technology is unable to reach high efficiency at low cost. Our simple and elegant “nanorectenna” device has a much higher efficiency potential than semiconductor devices and promises to be cheaper to fabricate.
Our technology is based on the geometric asymmetry of nanorectenna tunneling devices modified by Atomic Layer Deposition (ALD). The device’s pointed tip, in conjunction with the flat collector anode, gives rise to a net tunneling current. Because our device relies on geometric asymmetry to bring about a rectified DC current, the material or temperature asymmetries used in MIM or Schottky diodes are of secondary importance.
Incredibly small and fast response tunnel diodes can harvest and convert solar radiation from the infrared region through the visible.
The devices harvest the energy rich portion of the full solar spectrum, creating maximum efficiency.
These rectennaes have long lifetime, high thermal stability and operate above semiconductor temperature thresholds.
