Degradation Analysis of Polymer Solar Cells by Imaging Methods — •Harald Hoppe — Institut für Physik, TU Ilmenau, 98693 Ilmenau, Deutschland

Accelerated progress in device performance and processing technology of organic solar cells opens up the opportunity of their commercialization. Besides high performance, good processability and prospected low production costs, the photovoltaic devices require long term stability in order to face practical applications. Hence investigations of device degradation and improvements of their stability are one of the most actual research topics that need to be addressed. It is shown that imaging methods such as luminescence or thermography imaging are powerful tools to learn about the dominant degradation mechanisms of to dates state-of-the-art polymer solar cell architectures. An overview of most probably origins for device failure is presented, which provides valuable hints for constructive device stabilization.
