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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Photovoltaic cell with responsive surface film","description":"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 comm","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11495858","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
