Symposium Scope / Topics
Inorganic semiconductors have long underpinned thin-film solar energy conversion, from established photovoltaic technologies such as CdTe and Cu(In,Ga)(S,Se)₂ (CIGS) to a growing portfolio of next-generation materials inspired by these pioneering systems. This symposium welcomes contributions on inorganic materials for photovoltaics, solar energy harvesting, solar-assisted water splitting, and electrochemical CO₂ reduction. Topics of interest include, but are not limited to, established chalcogenide absorbers (e.g., CdTe and CIGS), emerging chalcogenides and chalcogenide-based materials (Sb₂S₃, Sb₂Se₃, CuSbS₂, Cu₂ZnSn(S,Se)₄, and related compounds), metal oxides (BiVO₄, Fe₂O₃, FeZrO₂, CuBiO, ZnFe₂O₄, and related materials), metal nitrides (ZnSnN₂), metal oxynitrides (TiON, ZrON, TaON, and related compounds), as well as other emerging inorganic semiconductors and energy materials. We welcome contributions spanning theoretical studies, materials synthesis, characterization, device physics, stability, and scalable manufacturing.
Sub topics include:
- Theoretical prediction, modelling and computational design of inorganic solar absorber materials.
- Synthesis and characterization of emerging inorganic photoabsorbers, charge-transport layers and transparent conductors.
- Thin-film chalcogenide materials and devices for photovoltaics and solar energy conversion.
- High-efficiency solar cells, solar fuel devices and photocatalytic systems.
- Multijunction, semitransparent, bifacial and flexible devices.
- Novel electrocatalyst design, synthesis and characterization for solar fuel production and CO₂ reduction.
- New device architectures for photovoltaics, solar water splitting, photocatalysis, photoelectrochemistry and CO₂ reduction.
- Nanostructuring strategies for absorbers and interfaces.
- Novel approaches for enhancing light absorption, including up/down conversion, photonic structures and solar concentration.
- Advanced characterization, structure–property relationships, defect and interface engineering.
- High-throughput techniques, data-driven approaches and machine-learning-assisted materials discovery.
- Reliability, degradation mechanisms and long-term stability of energy conversion devices.
- Scalable processing, manufacturing and integration of inorganic energy materials and devices.
