Thin film chalcogenide photovoltaic materials

The Thin Film Chalcogenide Photovoltaic Materials symposium 2022 will follow the previous editions with a focus on Cu(In,Ga)Se2, Cu2ZnSn(S,Se)4, CdTe, Sb-based chalcogenides, chalcogenide perovskites and new chalcogenide based materials for energy applications. The symposium provides a platform for researchers in the domains of absorber synthesis, characterization, and modelling. Thereby, the symposium fosters discussions to push the understanding and ultimately the power conversion efficiency of chalcogenide-based PV. The chalcogenide community needs to meet physically next year, and we believe that the E-MRS is the right venue for that.

Scope:

Chalcogenide based materials will play an important role in the transition to a green carbon neutral energy production on massive scales. These direct bandgap semiconductors exhibit low manufacturing costs, high material utilization and reduced energy payback time. They can be processed on flexible substrates and are robust against typical environmental operation conditions such as heat and moisture. Some material systems, such as CdTe and CIGSe are available on the market with record efficiencies exceeding 22% in the laboratory and 18-19% in modules. Other emerging chalcogenide-based materials, amongst others kesterites, Sb-based chalcogenides, chalcogenide perovskites are currently studied extensively as absorbers for single and multi-junction devices.
One of the most important property of these materials systems is the tuneability of the optoelectronic properties. This allows researchers to develop dedicated material combinations that allow for efficient tandem and multijunction devices, thereby paving the way to surpass traditional single junction devices and ultimately break the Shockley-Queisser limit for chalcogenide based thin film PV.
This symposium aims to provide a platform to present and discuss fundamental research across the various material systems, to improve the understanding of these very complex materials and develop mitigation strategies to surpass the current bottlenecks of the individual technologies. The symposium aims to bridge the gap from fundamental semiconductor science to improvements in device performance.
The symposium thereby brings together scientists from various disciplines and technologies to discuss improvements in absorber opto-electronic properties, interface passivation strategies, novel concepts such as multijunction devices, micro-solar cells and concentrator photovoltaics and improved concepts for modeling.
The chalcogenide symposium has a long tradition over the last decades to attract scientists from all over the world to present their best science at E-MRS. It has often been one of the largest symposia at the E-MRS conference, surpassing 200 participants. The symposium consists of invited, contributing talks, posters and discussion sessions. Furthermore, a young scientist tutorial has been organized regularly to promote discussions among young researchers in the field. We plan a similar structure for E-MRS 2022.

  • Chalcogenide PV materials, theory and modelling
  • Novel/ alloyed chalcogenide materials
  • Processes for film synthesis
  • Sustainable PV materials and processes
