Our Photovoltaic Material Laboratory is at the forefront of developing cutting-edge chalcogenide-based photovoltaic technologies, with a primary focus on materials such as Sb₂Se₃ and SbSeI for both outdoor and indoor applications. In addition to these, we are also exploring novel chalcogenide materials like GeS, Zn(Al,In)₂S₄, and AB_X3 (A=Sn, B=Zr, Ti, X=S, Se) at both fundamental and device levels. Our group’s expertise and competence are concentrated in the following areas:

• Structural characterization of chalcogenide crystals, thin films, and the resulting device structures.
• Deposition of Sb-based and other chalcogenide thin films using vacuum deposition methods, including vapor transport deposition and (rapid) thermal evaporation.
• Formation of window and buffer layers, such as TiO₂, ZnO, Cu₂O, and ZnIn₂S₄, using solution-based and vacuum deposition methods.
• Comprehensive characterization of solar cell performance under various illumination conditions.
• Development of new characterization methods and equipment.
