<p>The present invention relates to a large area solar for easily configuring a solar cell module. More particularly, the present invention relates to a large area dye-sensitized solar cell of back contact current collection type capable of easily solving the problem of corrosion of an opposite electrode while maintaining high current collection efficiency by a simple back contact current collection. It include an upper substrate which is made of a material of transmitting sunlight and has a lower surface where an upper electrode is formed, and a lower substrate which has an upper surface where a first lower electrode layer is arranged and a lower surface where a second lower electrode is arranged. The lower substrate includes penetration holes which penetrates the lower substrate and has a unit structure and a photoelectron path layer which is inserted into the penetration hole to allow one end to be connected to the upper electrode layer and allow the other end to be the second lower electrode layer, forms a path which allows photoelectrons generated by sunlight to flow from the upper electrode layer to the second lower electrode layer, and collects them on the second lower electrode layer.</p> |
