Motivated by the opportunity to address the challenges of toxicity and instability affecting lead-halide perovskites, researchers have been turning their attention to the development of new hybrid and inorganic solar absorbers. With advances in the fields of two-dimensional perovskites, emerging metal halides, chalcogenides, and chalcohalides, a plethora of promising photovoltaic absorbers has been discovered, and their properties have been increasingly well understood. This exciting class of materials includes Ruddlesden-Popper perovskites (A2BX4), Dion-Jacobson perovskites(ABX4), double perovskites (A2BB’X6), ABZ2 semiconductors, rudorffites, heavy-pnictogen chalcohalides, and pnictides.

Our symposium aims to facilitate a comprehensive discussion among experts in the fabrication, simulation, and characterization of this emerging class of semiconducting materials. By bringing together a range of different perspectives and skill sets, we hope to promote a deeper understanding of these new solar absorbers and accelerate their development.

We invite contributions that cover a broad range of topics, including fabrication methods (such as solution processing and thermal evaporation), characterization and the development of structure-properties relations, and photophysical studies.
