  • Photovoltaic cell with responsive surface film
    Patent number: 11495858
    Abstract: A photovoltaic (PV) cell health monitoring apparatus includes a Radio Frequency Identification (RFID) tag mounted to the PV cell and having identifying information of the PV cell, and a sensor in communication with the RFID tag for measuring health information of the PV cell. The RFID tag stores the measured health information together with time and locality information of the PV cell and responds to an interrogation signal by transmitting the stored information together with the identifying information. A dust sensor in the form of a comb-like electrode array measures electrical capacitance as an indication of an amount of dust on an exposed surface of the PV cell. An RFID tag antenna arranged as a meander-line patch antenna covered with polyethylene has a dual function as a temperature sensor.
    Type: Grant
    Filed: February 24, 2020
    Date of Patent: November 8, 2022
    Assignees: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALS, MASSACHUSETTS INSTITUTE OF TECHNOLOGY
    Inventors: Muhammad A. Hawwa, Hussain M. Al-Qahtani, M. Wasim Raad, David E. Hardt
