Photovoltaic Applications

Production of photovoltaic cells is rapidly growing as an important source of world electrical energy.  Many different cell materials and designs are now in production.  Research institutions and numerous solar energy start-ups continue to search for cost-efficient next-generation cells, such as organic thin films, that promise low production cost, reliability and ease of manufacture.

Solar panel manufacturer long recognized that to achieve higher efficiency, reliability and extend product life a real-time contactless monitoring of solar cell manufacturing process is necessary.  One of the biggest challenges for manufacturers is contactless control of thin-films thickness and uniformity.

Wide Range of Applications:
  • Thickness and uniformity measurement of:
    • Ultra thin conductive coatings on non-conductive
    • Non-conductive coatings of conductive materials
    • Conductive films on other conductive materials
    • Conductive metallic or non-metallic films
    • Conductive organic thin films
    • Transparent conductive oxide (e.g. ITO)
    • Conductive transparent, non-transparent of opaque films, etc.
  • Measurement of dielectric permittivity
  • In-situ film thickness measurement
  • Concurrent, multi-point, user-defined measurement of thin films
  • In-situ process control
  • Remote temperature measurement and monitoring (ambient to 800C)
Key Features:
  • Enables contact-less, fast and accurate measurement of very thin films
  • Simplifies manufacturing process, as one IRT tool can be used for a variety of metrology applications, including real time process monitoring
  • Provides a cost-effective alternative for multi-layer structure analysis
