That is, the bandgap increases as the ionic radius of A-site decreases, which is due to the modulation of the Pb-I bond originating from the size effects of A-site cations . Substituting Pb with Sn will result in a remarkable reduction in bandgap, making Pb–Sn mixed perovskites ideal rear sub-cells for all-perovskite TSCs (Fig. 2 g) [ 44, 45 ].
2.8: Periodic Systems
Arrows in the lower right corner of panel (b) illustrate the definition of energy band (left(Delta E_{n}right)) and energy gap (left(Delta_{n}right)) widths. However, maybe the most important fact, clearly visible in Fig. 26, is that there is an infinite number of energy bands, with different energies (E_{n}(q)) for the same value of (q) .
