    • It is an object of the present invention to minimize an electrode in a solar cell to minimize the solar cell. The present invention provides 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 over the photoelectric conversion layer, forming an opening reaching the first electrode layer in the photoelectric conversion layer, and forming a second electrode layer by filling the opening with a conductive paste, wherein the organic layer modifies the surface of the photoelectric conversion layer and a contact angle between the conductive paste and the photoelectric conversion becomes greater. According to the present invention, wettability of a photoelectric conversion layer can be decreased by forming an organic layer on a surface of the photoelectric conversion layer. Thereby an electrode layer and an insulating isolation layer can be thinned.
    • 本发明的目的是使太阳能电池中的电极最小化以最小化太阳能电池。 本发明提供一种太阳能电池的制造方法,包括以下步骤:在基板上形成第一电极层,在第一电极层上形成光电转换层,在光电转换层上形成有机层,形成开口到达 第一电极层,并且通过用导电膏填充开口形成第二电极层,其中有机层改性光电转换层的表面,并且导电糊和光电转换之间的接触角变得更大 。 根据本发明,通过在光电转换层的表面上形成有机层,可以降低光电转换层的润湿性。 由此,可以使电极层和绝缘隔离层变薄。
