Band versus Polaron: Charge Transport in Antimony Chalcogenides

“…Our results indicate that careful control of defect concentrations is essential for preventing degradation of device efficiencies. This agrees well with previous experimental reports that the defect density is crucial to the carrier transport in Sb 2 X 3 , whereby bulk defect densities above 10 15 cm –3 led to significant degradation in conversion efficiency. − Furthermore, considering that most experimental mobility measurements in Sb 2 X 3 were obtained from thin films, where grain boundary (GB) scattering will further lower the mobility, we also tested the inclusion of mean free path scattering. According to our results (Figure S2 and Table S3), the mobilities in Sb 2 X 3 are not significantly affected by GB scattering, even with grain sizes down to 10 nmmuch smaller than the domain sizes typically seen in experiments. − Accordingly, our results suggest that GB scattering is unlikely to be a dominant source of scattering in Sb 2 X 3 thin films, in agreement with previous studies …”

Lead-free, formamidinium germanium-antimony halide (FA4GeSbCl12) double perovskite solar cells: the effects of band offsets

“…In general, the conversion of photo-generated electron–hole pairs to photo-generated current and their transport without or with reduced recombination issues happens when the absorber layer thickness is lower than the charge carrier's diffusion lengths. 52 In this case, the solar cell demonstrated higher performance. Conversely, photon absorption is reduced if the absorber thickness exceeds the charge carrier's diffusion lengths.…”
