Emerging chalcogenide materials for thin film photovoltaic applications - #ChalcoPV
Description of topical focus

Chalcogen-containing materials have been used as light absorbers for photovoltaic applications, and some of them (like CIGS or CdTe) are a mature technology, with high efficiency and commercial availability. Beyond these established materials there are numerous chalcogen-based compositions at an early stage of research that show intriguing optoelectronic properties, appealing for energy generation. Despite the shared presence of chalcogen anions, these absorbers can present extremely varied characteristics, hindering the generalisation of new findings across diverse material families. However, these devices often present similar limitations (such as large V losses) which, even if originated by different causes, could be overcome by similar strategies.
This symposium will bring together researchers working on chalcogenide compounds, sharing insights on the basic material properties and resulting photovoltaic devices. Given the variety of compositions involved and their different level of development, several topics will be explored, incorporating both computational and experimental studies.
We hope that bringing the chalcogenide materials community together at this symposium will allow transfer of understanding between these different material systems, accelerating the development of solutions to tackle both the material-specific and group-characteristics issues currently limiting device performance.

List of conference topics
  • Binary chalcogenides absorbers (PbCh, Cu2Ch, Ag2Ch, Bi2Ch3, Sb2Ch3…)
  • Ternary chalcogenide absorbers (CuInCh2, AgBiCh2, Cu2SnCh3…)
  • Quaternary chalcogenide absorbers (Cu2ZnSnCh4…)
  • Chalcogenide perovskites (BaZrS3, LaYS3…)
  • Mixed compositions such as chalcohalides (BiSI, BiOI…)
