NOVELTY - Photoelectric module comprises: (a) a light-receiving substrate (110); (b) a first functional layer (130); (c) a first bus electrode (160); (d) a counter substrate (120) having a second functional layer (140) formed on it; (e) a second bus electrode (170) formed on at least two edges of the counter substrate; (f) an electrolyte layer (150); (g) a first connection line (180); and (h) a second connection line (190).    USE - The photoelectric module is used for converting light into electricity.    ADVANTAGE - The photoelectric module is capable of improving the efficiency of solar cells by including a current collecting unit that is formed along edges of a substrate and reduces an electron transfer resistance.    DETAILED DESCRIPTION - Photoelectric module comprises: (a) a light-receiving substrate (110); (b) a first functional layer (130) formed on the light-receiving substrate; (c) a first bus electrode (160) formed on at least two edge regions of the light-receiving substrate, where the first bus electrode is electrically connected to the first functional layer; (d) a counter substrate (120) having a second functional layer (140) formed on it; (e) a second bus electrode (170) formed on at least two edges of the counter substrate, where the second functional layer is electrically connected to the second bus electrode; (f) an electrolyte layer (150) disposed between the first functional layer and the second functional layer; (g) a first connection line (180) electrically connected to the second bus electrode; and (h) a second connection line (190) electrically connected to the first bus electrode.
