We have reported the synthesis, crystal structure and properties of CuBiSeCl2, a previously unreported, p-type chalcohalide semiconductor with low thermal conductivity and a suitable band gap for solar absorbing applications. Cationic displacements that arise from heterogenous bonding induced by the different anions result in anisotropic charge carrier transport, with light effective masses observed in the a direction. As such, for development of this material as a thin film for application as a potential solar absorber, a axis oriented deposition is suggested to utilize the superior effective masses along this direction. CuBiSeCl2 is an example of the opportunities for property modification through application of mixed anion chemistry, as shown by the variations in the structural, electronic and physical properties of CuBiSeCl2 relative to known materials with similar structures.
