Optical and electrical characterization of chemical bath deposited Cd-Pb-S thin films

► CdzPbyS thin films were deposited by chemical bath deposition. ► Polycrystalline mixture of hexagonal and cubic phases is observed. ► The band gap energy varied from 2.47 eV to 0.49 eV. ► Grain boundary scattering and variable range hopping conductions are observed. ► Thermoelectric power measurements showed n-type conduction.
