Abstract

By using microwave-assisted chemical deposition (MA-CBD) technique, lead selenide (PbSe) thin films were successfully synthetized at 80 °C and different growth times (3, 4, and 5 min). The films were analyzed by means of X-ray diffraction (XRD), energy-dispersive X-ray (EDX), and UV-Vis spectroscopy. Also, their electrical properties, such as conductivity, Seebeck coefficient, carrier concentration, and carrier mobility, are presented. Homogeneous films with thickness in the range 120–165 nm and large size of 22.9–24.5 nm were obtained. The dislocation density and micro-strains were found to vary inversely proportional to the crystallite size. Three and five-element thermocouples were tested with thermoelectric potential of up to 1.59 mV K −1 . The values of energy band gap of 0.75–0.64 eV, electrical conductivity of 9–28Ω −1 cm −1 and Seebeck coefficient of 213–232 μV K −1 suggest that MA-CBD is an effective synthesis technique to produce PbSe thin films for photovoltaic and thermoelectric applications.
