· JVASP-54849· KSnSe2

KSnSe2 is a ternary chalcogenide ceramic compound composed of potassium, tin, and selenium. This material belongs to the family of metal chalcogenides, which are primarily investigated for photovoltaic, thermoelectric, and optoelectronic applications where semiconducting properties and bandgap engineering are critical. KSnSe2 remains largely in the research phase, with potential utility in next-generation solar cells, solid-state electronic devices, and thermal-energy conversion systems where layered chalcogenide structures offer advantages in efficiency and manufacturing scalability compared to traditional semiconductors.
