Abstract
A photoelectric conversion element includes a first electrode section; a second electrode section; an electron-transporting section between the first electrode section and the second electrode section; a light-absorbing section; and a hole-transporting section. The hole-transporting section has a peak that reaches maximum at a Raman shift of 1575 cm±10 cmand a peak that reaches maximum at a Raman shift of 1606 cm±10 cmin a Raman spectrum obtained by emitting laser light having a wavelength of 532 nm; and has a peak intensity ratio A/B of 0.80 or more, the peak intensity ratio A/B being obtained from a maximum peak intensity A of the peak that reaches maximum at 1575 cm±10 cmand a maximum peak intensity B of the peak that reaches maximum at 1606 cm±10 cm.
