  • Photodetectors for measuring real-time optical irradiance
    Patent number: 12723913
    Abstract: A skin-wearable photodetector module includes an array with a plurality of photodetectors and a plurality of optical filters, and each photodetector is configured to receive an optical input from an optical filter having a central wavelength in a wavelength range of about 100 nm to about 1000 nm. Each photodetector includes a substrate with a first major surface having an electrode thereon, and a second major surface overlying an optical filter, an anode within an interior region of the electrode, an active layer including a. ternary mixture of an electron donor, an electron acceptor, and at least one charge carrier trap material, and a cathode that contacts the active layer.
    Type: Grant
