Abstract
A wireless temperature profiling system and the methods of making it are disclosed. The wireless temperature profiling system can include a photovoltaic substrate, a transponder, and a reader.
Claims43
A system for measuring an environment temperature of a photovoltaic substrate during a photovoltaic module manufacturing process, comprising:
- a transponder adjacent to the photovoltaic substrate which measures the environment temperature during the photovoltaic module manufacturing process and sends a temperature signal corresponding to the environment temperature;
- and
- a reader which sends a sweep signal and picks up the temperature signal from the transponder.
A method of reading an environment temperature of a photovoltaic substrate during a photovoltaic module manufacturing process, the method, comprising:
- providing a transponder adjacent to the photovoltaic substrate which reads an environment temperature during the photovoltaic module manufacturing process and returns a temperature signal corresponding to the temperature;
- providing a reader which sends a sweep signal and picks up the temperature signal from the transponder;
- generating a temperature signal from the transponder;
- receiving the temperature signal with an antenna connected to the reader;
- and
- converting the temperature signal to a corresponding temperature.
3 more elements
A wireless temperature profiling system for communicating with at least one transponder moveable along an interrogation path comprising:
- a photovoltaic substrate moving along said interrogation path during processing to form a photovoltaic module;
- a plurality of transponders adjacent to the photovoltaic substrate moving along the interrogation path, wherein each of the transponders simultaneously sends a temperature signal corresponding to an environment temperature;
- a plurality of readers along the interrogation path, wherein each of the readers simultaneously sends a sweep signal and picks up a signal from a transponder.
