    The future is left to us!

    As I left EMIL, I could not stop from reflecting to Núria’s words and wonder: how is it possible that part of the World’s population still refuses to accept that the World’s primary energy demand increases and the Climate Change is getting worse, regardless of the fact that researchers and environmentalists work non-stop to tackle these problems? How many more fancy machines and lab equipment do …

    But what does a perovskite-based solar cell look like?

    Not to leave you wondering how a perovskite-based solar cell looks like, I would like to conclude my writing with a short explanation about them. Part of the information was again provided by Núria during our conversations, but the summary that follows is thanks to her written Master thesis introduction which she unselfishly shared with me and I am beyond grateful for that.In order to obtain a …

    From deposition to analysis – all at EMIL

    Let´s come back to the perovskite. As mentioned before, the perovskite thin film in Nuria’s work is Pb-free. Therefore, she uses SnCl2 in addition to a CH3NH3I3 precursor (Methylammonium Iodide or shortly MAI). These are the precursors that are deposited during the evaporation phase explained above. Núria and I evaporated SnCl2 in of EMIL’s chambers, but MAI’s evaporation is executed outside of …

    EMIL´s UFO-like deposition compartments and the importance of pressure behavior

    Post 1, Post 2, Post 3 and Post 4Núria clicks on a computer – and a glass sample starts to move from one chamber of the UFO-like looking compartments to another. I find it fascinating how fast and precise everything is and how my and Núria’s work at this point comes down to keeping a close look on the temperature and pressure of the set-up which can be read from displays on the left and right from …

    Crystal growth and the magic temperature

    Post 1, Post 2 and Post 3The basic idea is to form the so called perovskite crystal structure applied as thin layers on (usually) a TiO2/FTO substrate. One requirement to obtain high performances is to have closed layers that homogeneously cover the substrate. However this is not as simple as it sounds since the layer fabrication is very sensitive to many external conditions such as the selection …

    The mystery of perovskites

    Post 1 and Post 2 The question we all might have though is: What are perovskites? When it comes to solar cells, most of us are aware that the highest energy market share is still owned by crystalline silicon-based solar cells. However, in the past years perovskite-based materials and their utilization in solar cells that exhibit rapid efficiency increase have been intriguing researchers.The type …

    Entering the high-tech lab EMIL

    It was the end of October and I was starting to count the end of my intern days at the Helmholtz Zentrum in Berlin. However, I already knew that before I left, this research institute would offer me once again an amazing opportunity to observe and learn about its great labs and edge-cutting research. One workshop on scientific writing during my internship stirred up my ever-present passion about …
