Workshop on the Assessment of Defects in PV Modules

Workshop on the Assessment of Defects in PV Modules

by Stephan Raithel, SEMI Europe 

Intersolar Europe 2014
Hall A3, Room A31/A32 (first floor)
June 5, 2014


Advanced characterization techniques such as electroluminescence and photoluminescence are capable to identify defects in solar modules with crystalline Si solar cells. However, little is known how the various defects impact the long-time performance of the modules. Therefore the PV Materials Committee of SEMI Standards organize a half day workshop in conjunction with Intersolar Europe that addresses the assessment of defects in modules and their potential impact on the long-term performance. This should help in characterizing module defects and to develop methods to eliminate them. The following topics will be discussed:

  • Methods for identifying and characterizing defects in PV solar modules
  • Impact of module defects on module long-term performance
  • Categories of module defects and models for prediction of power performance.
