Abstract
According to one embodiment, a solar cell includes a first electrode, a second electrode, and a photoelectric conversion layer disposed between the first electrode and the second electrode. In a case where a photoluminescence spectrum of the photoelectric conversion layer is measured at a temperature of 100 K or lower, a first maximum value (A) which is a maximum value of emission intensity in a wavelength range of more than 650 nm and 1000 nm or less is 100 times or less of a second maximum value (B) which is a maximum value of emission intensity in a wavelength range of 600 nm or more and 650 nm or less (A≤100B).
