SOLAR CELL, SOLAR CELL PANEL, AND DEVICE COMPRISING SOLAR CELL

摘要

A solar cell (1) of the present invention includes a photoelectric conversion layer (2) and a photonic crystal provided inside the photoelectric conversion layer (2) in order to have a photonic band gap. The photonic crystal has defects (31) in order to provide a defect level in the photonic band gap. QV which is a Q value representing a magnitude of a resonance effect yielded by coupling between the photonic crystal and an outside is substantially equal to Qαwhich is a Q value representing a magnitude of a resonance effect yielded by a medium of the photoelectric conversion layer (2).
