exploring ehalgogenide ABX3 perovskites: challenges and insights from physical vapor deposition — •Sebastian Zimmermann¹, Roland Scheer², and Torsten Hölscher¹ — ¹B5 Photovoltaics, Just Transition Center, Martin Luther Universität Halle-Wittenberg — ²Photovoltaics Groups, Martin-Luther-Universität Halle-Wittenberg

The discovery of new solar cell materials is crucial for the next generation of multijunction systems in photovoltaics. This work focuses on synthesizing thin-film materials that are theoretically well suited for photovoltaic applications. To form these materials, we use physical vapor deposition (PVD). At the beginning, we aim to synthesize chalcogenide perovskites. Chalcogenide perovskites are crystals with a perovskite structure (typically ABX3), where X stands for selenium or sulfur, A for group II metal like Ca or Ba and B for a transition metal like Ti or Zr. Compared to other perovskites, their advantages include lower toxicity and the predicted long-term stability of the layers. This talk presents results of microstructural analysis of PVD synthesized chalcogenide perovskite films and discuss challenges encountered during synthesis. Our results provide new insights in the field of photovoltaic materials and are intended to open up new perspectives for multijunction thin-film solar cells.
