J–V curves (a) and the steady-state power output (SPO) (b) of perovskite solar cell devices fabricated with and without 2OH. The inset shows the detailed photovoltaic parameters. c PCE distribution of perovskite solar cells with and without 2OH. d I–V curves of the champion perovskite mini-modules (aperture area: 20.8 cm²) for control and 2OH treated devices. Inset, a photograph of the mini-module. e I–V curves of the champion 30 × 30 cm sub-module (aperture area: 728.0 cm²) with 52 series-connected subcells under reverse and forward scans. Inset, a photograph of a 30 × 30 cm sub-module. f MPP tracking of perovskite devices fabricated with and without 2OH under continuous one-sun light soaking at ~50 °C.
