Online Conference

The Online Conference on Device physics characterization and interpretation in perovskite and organic materials (DEPERO) will take place from the 3rd to the 5th of October 2023.

Perovskite devices have made huge gains in performance over the past decade. However, there are still significant losses associated with non-radiative recombination in the bulk and at interfaces with the transport layers. This is especially true, when regarding not only the highest efficiency compositions but compositions that are needed e.g. for higher stability or a wider range of band gaps for applications in multi-junction solar cells, LEDs and memristors. Therefore, accurate characterization of fundamental parameters such as recombination lifetimes and band energy alignment is important for developing effective mitigation strategies to improve efficiencies in different perovskite compositions.

This conference will bring together the leading experts on the interpretation of different characterization methods of perovskite and organic devices. These characterization methods include steady-state and transient photoluminescence, time domain (transient photovoltage and transient photocurrent) and frequency domain small perturbation methods (impedance spectroscopy, intensity-modulated photocurrent spectroscopy and intensity-modulated photovoltage spectroscopy), surface physics methods (X-ray photoelectron spectroscopy and ultraviolet photoelectron spectroscopy) and drift-diffusion simulations. Related topics include electronic structure calculations and machine learning methods for the characterization of these devices.
