Abstract: A light-absorbing material includes a compound, wherein the compound has a perovskite crystal structure represented by the formula AMX3 where a Cs+ ion is located at an A-site, a Ge2+ ion is located at an M-site, and I− ions are located at X-sites, and at least a part of the compound has an orthorhombic perovskite crystal structure. An X-ray diffraction pattern of the compound measured using Cu Kα radiation may have a first peak at a diffraction angle (2θ) of 25.4° or more and 25.8° or less and a second peak at a diffraction angle (2θ) of 24.9° or more and 25.3° or less, and an intensity of the first peak may be 30% or more of an intensity of the second peak.
