Characterisation of photoluminescence and absorption in hybrid perovskite thin films — •Seth Niklas Schumann, Sebastian Reichert, Alexander Wagenpfahl, and Carsten Deibel — Fakultät für Naturwissenschaften, TU Chemnitz, D-09126 Chemnitz
In the last few years the organic-inorganic hybrid perovskite solar cells came to attention due to their impressive power conversion efficiency increase to above 20 %. They also are expected to have low manufacturing cost. To take advantage of the potential the hybrid perovskites have to offer for photovoltaics we need to characterise the active layer regarding layer homogeneity and optical properties. For our active layers we used the CH3NH3PbI3 material system which we processed using the interdiffusion approach. We optimized the processing parameters to obtain homogeneous and pinhole free thin films. We characterised these thin films using photoluminescence, absorption and excitation spectroscopy.
