Influence of the optical microcavity effects on the emission and absorption of perovskite solar cells — •Jakob Wolansky, Christian Wolff, Lorena Perdigón-Toro, and Dieter Neher — University of Potsdam, Institute of Physics and Astronomy, Germany

Perovskite solar cells are thin-film devices with usual thicknesses of some hundred nanometres, comparable with the wavelength of absorption and emission of light. Therefore, microcavity effects can influence the device emission and absorption properties, and finally its photovoltaic response.

In this work several parameters of the device stack are varied (e.g. thickness of the perovskite and the transport layers) and their influence on the luminescence and absorption spectra are consequently investigated. This is complemented by a detailed study of the electroluminescence and external quantum efficiency and their correlation via the reciprocity relation by U. Rau[1]. Finally, angular dependent measurements are performed and compared to the results of optical modelling.
