Cu0.4In1.6Se2.6 is a ternary chalcogenide semiconductor compound belonging to the I–III–VI family, related to the CuInSe2 system used in photovoltaic absorber layers. This material is primarily studied in research contexts for thin-film solar cell applications, where controlled copper deficiency and indium excess are explored to optimize bandgap and carrier transport properties. It represents an experimental composition variant designed to improve efficiency and stability compared to stoichiometric CuInSe2, making it relevant for next-generation photovoltaic device engineering.
