The present invention provides a novel photoelectric conversion element and a photoelectric conversion module, which are intended to be used as a neutral density filter having both appropriate translucency and visibility, have little color unevenness, and are excellent in design. An electrode having a semiconductor layer carrying a dye, a counter electrode facing the semiconductor layer, and an electrolyte layer disposed therebetween, the electrolyte layer being a sealing material. 8 is a portion where the semiconductor layer and the electrolyte layer are seen through when viewed from one surface to the other surface, and the other portion is a sealing portion. The transmittance T1, T2 at the sealing portion and the photoelectric conversion portion of light having a wavelength of 550 nm is 0.1 to 40%, T1 / T2 is 0.05 to 20, and between the photoelectric conversion portion and the sealing portion, L * a * b * based on the notation system △ L *, △ a *, △ b * color difference is calculated by the following formula from the values △ E * ab is a photoelectric conversion element 15 or less. ΔE * ab = [(ΔL * ) 2 + (Δa * ) 2 + (Δb * ) 2 ] 1/2 [Selection] Figure 1 |
