Influence of bulk defects in SnS absorber layer on optical and electrical properties of solar cell

Abstract In this research, the effect of bulk defect on the performance of the solar cell was studied by using the AFORS-HET simulation program. This was done by varying the density of defects including both Acceptor-like and donor-like within the SnS absorption layer. The thickness of the SnS layer was changed from 600nm to 9000nm with the change in bulk defect density in the same layer from (1E10 to 1E17 cm−3). The results showed that when the density of defects is less than 1E14cm−3, it has no effect on the performance of the solar cell, but its effect appears after this concentration, On the contrary, it is the effect of thickness, the results showed that the change in thickness at the defect density of E16cm−3 does not affect on the optical and electrical properties. Also, the results showed that the effect of defects is greatest at low concentrations of Na impurities, and this effect begins to decrease with increasing the concentration of impurities.

Post Synthesis

Al -doped zinc oxide (AZO) thin films are deposited onto glass substrates using radio-frequency reactive magnetron sputtering and the improvements in their physical properties by post-synthesis thermal treatment are reported. X-ray diffraction spectra show that the structure of films can be controlled by adjusting the annealing temperatures, with the best crystallinity obtained at 400°C under a nitrogen atmosphere. These films exhibit improved quality and better optical transmittance as indicated by the UV-Vis spectra. Furthermore, the sheet resistivity is found to decrease from 1.87 × 10-3 to 5.63 × 10-4Ω⋅cm and the carrier mobility increases from 6.47 to 13.43 cm2 ⋅ V-1 ⋅ s-1 at the optimal annealing temperature. Our results demonstrate a simple yet effective way in controlling the structural, optical and electrical properties of AZO thin films, which is important for solar cell applications.
