Abstract
Provided is a solar-cell manufacturing method that is capable of preventing a conductive paste from bleeding and spreading on a photoelectric conversion body. In the provided method of manufacturing a solar cell, a first printing speed at which a first conductive material is printed is faster than a second printing speed at which a second conductive material is printed on the first conductive material.
Claims13
A method of manufacturing a solar cell that includes:
- a photoelectric conversion body;
- and a plurality of fine line electrodes each including a first conductive layer and a second conductive layer formed consecutively one upon the other on the photoelectric conversion body, the method comprising:
- forming the first conductive layer by printing a first conductive material on a textured surface of the photoelectric conversion body at a first printing speed;
- and
- forming the second conductive layer by printing a second conductive material on the first conductive layer at a second printing speed,
- wherein the first printing speed at which the first conductive material on the textured surface is printed is faster than the second printing speed at which the second conductive material is printed on the first conductive material.
