Though CuBiSeCl2 possesses heavy charge carriers in the c direction, this should not be a barrier to its implementation as a thin film for optical absorbing applications, providing it is grown in the correct orientation. For example, Sb2Se3 is a well-established solar cell absorber that also exhibits highly anisotropic effective masses. These anisotropic properties are overcome by orienting crystal growth perpendicular to the substrate, allowing for efficient transport along one axis. Sapurov et al. also report a method to deposit preferentially oriented thin films and depositing a axis-aligned CuBiSeCl2 could reduce the effects of the heavy charge carriers along the c axis on the material conductivity.
