Digital image of a perovskite ink composed of FA0.95Cs0.05PbI3 dissolved in GVL/DMSO mixture. (c) Cross-sectional SEM of the perovskite films fabricated from GVL/DMSO (top panel) and GVL/DMSO/2-MeTHF mixtures (bottom panel). The scale bars represent a length of 1 μm. (d) Schematic showing coordination of GVL and 2-MeTHF to perovskite. (e) Contact-angle images of the control and SCEP perovskite ink droplets. (f) Schematic illustrating solvent evaporation of the perovskite wet film. (g) J-V curves of the best-performing control and SCEP modules with a total area of 7200 cm2. (h) NREL-certified stabilized Pmax, Imax, and Vmax plots within 360 s for a module. (i) UV preconditioning test with a cumulative UV irradiation of 36 kWh/m2. (j) Damp heat test at 85°C and 85% RH conditions. RH, relative humidity. (k) TC comparison between perovskite modules and various types of crystalline silicon modules. Al-BSF, aluminum back surface field; PERC, passivated emitter and rear cell; SHJ, silicon heterojunction; TC, temperature coefficient. (l) Hot-spot endurance test of commercial-scale perovskite modules[8].
