Copper(I) telluride is an inorganic compound with the chemical formula Cu2Te. It can be synthesized by reacting elemental copper and tellurium with a molar ratio of 2:1 at 1200 °C in a vacuum.[3] Cu2Te has potential applications in thermoelectric elements and in solar cells, where it is alloyed with cadmium telluride to create a heterojunction.[4]
