4. 1 PV Module Design, Manufacture, Performance and Reliability
Stabilization, Dark Biasing, Thin Film (TF), Crystalline Silicon
Summary / Abstract:
In scope of stabilization of PV modules technologies, it has been a challenge for many measurement labs to stabilize the power in a shorter interval of time. Since, the usual standard procedure as stated in IEC 61215-1-x (x: technology type) is to keep to modules under illumination for a certain number of hours at its MPP load. An effort is being made to make the stabilization of modules faster and more reproducible before the actual performance determination. Since 2011, however, methods have also been proposed that work purely electrically, i.e. without illumination [1-3]. Therefore, this study aims to establish dark bias methods in comparison to conventional, exposure methods. Our goal is to establish a shorter, purely electrical stabilization procedure to mitigate the metastable effects in thin-film and faster measurements (thin-film and crystalline). The measurement results and reliability in regard to initial power stabilization for different technologies were compared.
