Lock-In Thermography Investigation of Polymer Solar Cells and Modules — •Maik Bärenklau, Roland Rösch, Burhan Muhsin, Marco Seeland, Gerhard Gobsch, and Harald Hoppe — Institute of Physics, Ilmenau University of Technology, Ilmenau, Germany

Since polymer-fullerene solar cells and modules are typically designed in a multilayer architecture, local defects such as shunts and short-circuits in the device can cause the breakdown of the whole cell or module. Further more, highly resistive series connection can be a major cause for efficiency loss in solar modules. For screening and characterization of such processing imperfections, we apply lock-in thermography (LIT), a highly sensitive thermographic imaging method. We show that LIT is a useful tool for non-destructive qualitity control of large area polymer solar cells and modules that allows detection of local defects with high heat dissipation and also to test the quality of encapsulation.
