PhD Position – Transient Spectroscopy of Halide Perovskites for Photovoltaics

titel

The Institute for Energy and Climate Research 5 – Photovoltaics (IEK-5) performs research on various aspects of photovoltaic materials and devices, including the emerging class of perovskite solar cells. Perovskite solar cells are a promising solar cell technology that enables printable, flexible and lightweight solar cells. To better understand and quantify efficiency losses, researchers use a variety of characterization methods that include various types of spectroscopy methods. Within this project, we will specifically studied the transient photoluminescence method and try to improve data analysis of photoluminescence transients on perovskite layers, layer stacks and complete devices using machine learning techniques. Our approach is based on a variant of Bayesian inference, where we use trained neural networks (supervised learning) to rapidly compare the experimental data with the output of a numerical model.
