A Schematic energy landscape for thick (left panels) and thin (right panels) BA2PbI4 films, shown in the dark (top panels) and under illumination (bottom panels). B I–V characteristics of the thick BA2PbI4 film in the dark, under full-spectrum one-sun illumination, and under one-sun illumination excluding violet/UV photons (energy > 2.95 eV). C I–V characteristics of the thin BA2PbI4 film in the dark and under full-spectrum one-sun illumination.
