Additionally, the absorption spectrum begins at very low incoming photons, confirming the crystal''s metallic nature, which has a higher value at an energy of 20 eV. Furthermore, systematic calculation of crystallite size, energy density, intrinsic stress, and strain, using the Scherrer formula, WH analysis, SSP, and HW method is accomplished.
Investigation of the Absorption Spectrum of InAs Doping …
InAs doping superlattice-based solar cells have great advantages in terms of the ability to generate clean energy in space or harsh environments. In this paper, multi-period InAs doping superlattice solar cells have been prepared.. Current density–voltage measurements were taken both in the dark and light, and the short-circuit current was …
Single-crystal halide perovskites: Opportunities and challenges
A tolerance factor is usually used to evaluate whether a pseudocubic perovskite structure can be maintained: 51 t = r A + r X 2 (r B + r X), where t is the tolerance factor, r A is the effective radius of the A-site general cation, r B is the effective radius of the B-site metallic cation, and r X is the effective radius of the X-site halide anion. Empirically, …

Perovskite Single-Crystal Solar Cells: Advances and Challenges
Tuning the single crystal thickness, they also proved how it was possible to benefit of the much higher charge diffusion length in combination with the higher thickness of perovskite SC to exploit below-bandgap indirect transition and so increase the absorption spectrum in comparison to their polycrystalline analogous (Figure 12a). Because ...
