By Dr. Marko Turek, Dr. Marko Turek studied physics at the Dresden University and received his PhD in the field of condensed matter theory at the University of Regensburg. At Fraunhofer Center for Silicon Photovoltaics (CSP) he leads the team for the electrical characterisation of solar cells.

Module degradation | Light-induced degradation has long been recognised for its negative effects on the performance of crystalline silicon solar cells. Researchers from Fraunhofer CSP explain
how with the advent of advanced materials and cell technologies such as PERC, new tests and standards are required to minimise the impact of the phenomenon on plant reliability.

It wouldn’t be an Intersolar Europe edition of this journal without a look at a solar market closer to home; we touch on the resurgent French solar market which looks set to provide a major source of demand. As module and inverter swap outs are a growing line of work for O&M providers, we also examine the issues that emerge, such as potential induced degradation and exposing the shortcomings of projects built without adequate monitoring capabilities. TUV Rheinland presents a technical paper that could prove to be an investor’s best friend by providing a method to push energy yield performance calculations for modules beyond an extrapolation of their standard test conditions. We also introduce our new conference, PV ModuleTech, to be held in Malaysia this November, dedicated to scrutinising the technical performance claims of manufacturers and seeking out best practice.
