Patent ID: 8455753

Claim:
A method for manufacturing a solar cell comprising the steps of: forming a first electrode layer over a substrate; forming a photoelectric conversion layer over the first electrode layer; forming an organic layer for decreasing wettability of an entire top surface of the photoelectric conversion layer over and in direct contact with the entire top surface of the photoelectric conversion layer; forming a first opening and a second opening reaching the first electrode layer in the photoelectric conversion layer after the organic layer is formed; forming a second electrode layer by filling the first opening with a conductive paste; forming an insulating layer by filling the second opening with an insulating material after forming the second electrode layer; and forming a conductive layer by a sputtering method over and in contact with the organic layer and the second electrode layer after the second electrode layer is formed, wherein bottom surfaces of the first opening and the second opening reach up to a top surface of the substrate, wherein the second electrode layer is formed by an ink jet method, and wherein a contact angle between the conductive paste and the photoelectric conversion layer becomes greater by providing the organic layer.
