Provided is a photoelectric conversion device including a first substrate (110); a second substrate (120) opposing the first substrate (110); a first electrode (113) formed on the first substrate (110); a second electrode (123) formed on the second substrate (120); an electrolyte layer (150) interposed between the first electrode (113) and the second electrode (123); and a semiconductor layer (118) in which a photosensitive dye is adsorbed, wherein the semiconductor layer (118) is interposed between the electrolyte layer (150) and the first electrode (113); wherein the first electrode (113) comprises a grid electrode (112), the grid electrode (112) comprising a plurality of finger electrodes (112a) extending parallel to each other, wherein the finger electrodes (112a) satisfy condition: 0.009 ‰¤ W/P ‰¤ 0.1, wherein W is the line width of the finger electrodes (112a) and P is a minimum distance between adjacent finger electrodes (112a). Accordingly, the photoelectric conversion device may have improved photoelectric conversion efficiency by using a collector electrode.
