a Calculated absorption spectra of 200 nm thick PbS in CTR and FP devices. b Normalized electric field intensity in the devices under 1-sun AM 1.5G illumination. c JSC of the devices with different PbS active layer thicknesses. The solid lines represent calculated JSC without considering diffusion limits of the charge carriers in the devices, and dotted lines represent experimentally measured JSC. Experimental d VOC, e FF, and f PCE of the devices
