Photo I–V curves of lead-free A3B2X9-crystal solar cells measured under simulated irradiation (AM 1.5, 100 mW cm−2) as normal mesoscopic and inverted architectures respectively. The photoabsorption layers were (CH3NH3)3Bi2I9 (a, b), (CH3NH3)3Sb2I9 (c, d), and (CH3NH3)3SbBiI9 (e, f) crystal films. The photovoltaic characteristics were summarized in Table 7
