· K2CuIn3Se6

K2CuIn3Se6 is a quaternary chalcogenide semiconductor compound belonging to the ternary sulfide/selenide family of materials, synthesized primarily for photovoltaic and optoelectronic research applications. This material is largely experimental and studied for thin-film solar cells and related energy conversion devices due to its tunable bandgap and layered crystal structure, positioning it as a potential alternative to more mature semiconductors like CIGS (Cu(In,Ga)Se2) in next-generation photovoltaic architectures.
