CuP2 is a copper phosphide semiconductor compound that belongs to the metal phosphide family, which are being investigated for optoelectronic and photovoltaic applications due to their tunable band gaps and relatively abundant constituent elements. This material is primarily of research and developmental interest rather than established in high-volume manufacturing, with potential applications in solar cells, photodetectors, and catalytic systems where conventional semiconductors face cost or performance limitations. CuP2 is notable within the phosphide semiconductor class for combining copper's good conductivity with phosphorus's semiconductor properties, offering a lower-toxicity and lower-cost alternative pathway compared to conventional III-V semiconductors or lead-based perovskites.
