Solar cell manufacturing method

A method of manufacturing a solar cell, comprising:

• forming a first electrode over one surface of a photoelectric conversion unit by screen printing of a first conductive paste;
• and
• forming a second electrode having a larger area than that of the first electrode over the other surface of the photoelectric conversion unit by screen printing of a second conductive paste having a lower viscosity than that of the first conductive paste,
• wherein each of the first conductive paste and the second conductive paste contains a conductive filler, a binder resin, and an solvent,
• at least one of a type and a content for at least one of the binder resin and the solvent differs between the first conductive paste and the second conductive paste,
• the first electrode comprises a plurality of first finger sections arranged in parallel to each other and the second electrode comprises a plurality of second finger sections arranged in parallel to each other, more of the second finger sections being provided than the first finger sections,
• the first conductive paste and the second conductive paste are cured by heating to form the first electrode and the second electrode such that the conductive filler is dispersed in the binder resin,
• the first conductive paste includes the binder resin which is not yet cured in the form of a solid which can dissolve in the solvent or in the form of liquid or paste at room temperature, and
• the second conductive paste includes the binder resin which is not yet cured in the form of a solid which can dissolve in the solvent or in the form of liquid or paste at room temperature;
• the conductive filler of the first conductive paste and the conductive filler of the second conductive paste are a same type of conductive filler.
