Photovoltaic devices rely on high-performance active absorber materials that efficiently convert light into charge carrier pairs (electrons and holes). Interfaces between active layers or between electrodes and active layers are arguably as important for good device performance, as they govern separation, recombination as well as collection of charge carriers. Interfacial layers may also be present in tandem solar cells for example as recombination junction between top and bottom cell. They may optimize light management in the device.The specific goal of this project is to develop a joint tool box of film deposition techniques and interface preparation techniques for improved contact formation. We aim at developing layers with properties with tuned work function needed for efficient charge collection (high work function for hole collection layers, low work function for electron collecting layers); appropriate refractive indices if optical functionality is required (e.g. as anti-reflective coating or intermediate reflector in a tandem design), soft deposition (not leading to damage of the optical absorber), transparency (needed for front contact, but also in future tandem configurations), high mobility if lateral conductivity is needed. These layers will be applied to the state-of-the-art processes of the individual labs, covering a wide range of devices, including CIGS based solar cells, perovskite solar cells and crystalline silicone heterojunction devices.
