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 DEG 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. 本发明涉及光吸收材料和太阳能电池，其中，方式的光吸收材料含有用组成式HC(NH)SnI表示的化合物，该化合物具有钙钛矿型结构，而且在采用2维NMR的H-N的HMQC法测得的固体H-NMR谱中，25℃下的6.9ppm的峰强度为7.0ppm的峰强度的80％以上。
