The PhD student Philipp Christ presents new result in the field of SOLAR TECHNOLOGY dealing with ORGANIC SOLAR CELLS.
In order to explore the full potential of these organic photovoltaics (OPV), there is a number of scientific challenges regarding material properties, aging effects and their integration in device architecture to be overcome.
As an example, the figure below shows the layer structure of such an OPV cell, which was visualised using a transmission electron microscope (TEM, a). By combining spectroscopic techniques like electron energy loss spectrometry (EELS) and energy dispersive X-ray spectrometry (EDX), the chemical structure of the active layer (b) and the absorption capacity (c) can be determined.
