Low-temperature synthesis and characterization of Sn-doped Sb2S3 thin film for solar cell applications

AgSbS2 and Ag3SbS3 absorber materials for photovoltaic applications

“…The higher value of 'a' shows that the material can be used as good absorbing material for solar cell application [1,9]. The result is comparable to the earlier reports on AgSbS 2 by W.C. Yang et al [1] CuSbS 2 by Bo Yang et al [12], Adam W. Welch et al [11] and Sn-Sb 2 S 3 by S. Mushtaq et al [10]. The type of optical transition can be explained by observing the dependence of the absorption coefficient, a on the photon energy, hn.…”

“…This result is better than the conductivity of Sb 2 S 3 thin film (0.024 mho cm À1 ) [10]. The increase in conductivity is due to the binding energy of surface electrons decreased with rising in annealing temperature (300 C).…”

“…A gradual absorption reduction is noticed between 500 and 600 in the AgSbS 2 and Ag 3 SbS 3 films attributed to the d-d transition of Ag. The solar conversion efficiency can be strongly influenced by the absorption coefficient (a)[10] that can be calculated from the following relation (Eqn. (2)),…”

Structural and spectroscopic ellipsometry studies on vacuum-evaporated Sn2m−4Sb4S2m+2 (m = 2.5, 3 and 4) thin films deposited on glass and Si substrates

“…To comfort this idea, we compared these results with the ones of Sn-doped Sb 2 S 3 thin films deposited by chemical bath deposition (CBD) technique on glass substrates at optimized low temperature of 10 °C [36]. X-ray diffraction analysis revealed that the deposited Sn-doped Sb 2 S 3 thin films are polycrystalline in nature [36], in spite of the fact that the poor grain growth at lower bath temperature is one of the drawbacks of the chemical deposition method [37].…”

“…X-ray diffraction analysis revealed that the deposited Sn-doped Sb 2 S 3 thin films are polycrystalline in nature [36], in spite of the fact that the poor grain growth at lower bath temperature is one of the drawbacks of the chemical deposition method [37]. The doping of Sn gives a better grain growth at lower bath temperatures [37].…”
