Abstract:
A light-absorbing material contains a compound represented by the composition formula HC(NH2)2SnI3 and having a perovskite structure. A solid-state 1H-NMR spectrum, which is obtained by 1H-14N HMQC measurement in two-dimensional NMR at 25° C., of the compound includes a first peak at 6.9 ppm and a second peak at 7.0 ppm. A peak intensity of the first peak is equal to 80% or more of a peak intensity of the second peak.
