Embodiment approach 1

[0114] [Preparation of paste for electrode formation]

[0115] A paste for electrode formation was prepared by the following procedure. That is, as the conductive powder, Ag powder with an average particle diameter of 2 μm was used. As the organic vehicle component, a vehicle containing ethyl cellulose as a resin component was used. In addition, as the glass frit, common lead borosilicate glass powder (average particle diameter: 0.5 to 1.6 μm) commonly used when preparing electrode-forming pastes in the field of electronic materials was used. And, the proportioning of these materials is set as the ratio that the mass percent of Ag powder is 85%, the mass percent of glass frit is 3 percent and the ratio of the mass percent of organic vehicle is 12 percent to mix, and uses three-roll kneader to By sufficiently kneading, a paste for electrode formation is formed.

[0116] The average particle size of the Ag powder is the cumulative 50% particle size in the volume-based particl...

Embodiment approach 2

[0153] When forming the grid electrode of the solar cell by printing, as shown in the following Table 6, the method of supplying the paste for electrode formation on the printing plate, the printing method, and the proficiency of the operator were changed to print 200 each. A substrate on which grid electrodes are formed. The effect of this on the appearance of the formed grid electrode was studied.

[0154] That is, as the paste for electrode formation, the paste for electrode formation of Sample 1 prepared in Embodiment 1 above which can form a high electrode was used.

[0155] Regarding the method of supplying the above-mentioned paste for electrode formation on the printing plate, in the column of "paste supply" in Table 6, the case where the operator uses a dispenser to provide the same as the above-mentioned Embodiment 1 is represented as "dispensing "" and "scraper" represents the case where the electrode-forming paste is scooped up by an operator using a spatula, prov...

Embodiment approach 3

[0167] When forming the grid electrode of the solar cell by printing, the aperture of the dispenser used when supplying the paste for electrode formation to the printing plate was changed, and 200 each were printed in the same manner as in Sample 1 of Embodiment 1. A substrate on which grid electrodes are formed. The effect of this on the appearance of the formed grid electrode was studied.

Abstract

The present invention provides a manufacturing method of a solar cell. The method comprises the following steps of preparing a paste; configuring a forme possessing a linear opening corresponding to a specified pattern on the surface of a first semiconductor substrate; providing the paste to an end part which is used as the first end part of the forme and comprises the opening part in a width direction orthogonal with a printing direction; on one hand, using a scraping plate to move the provided paste from the first end part of the forme to a second end part relative to the first end part, on the other hand, carrying out the first printing on the first semiconductor substrate by enabling the provided paste to pass the opening part; configuring a forme after the first printing on the surface of a second semiconductor substrate; on one hand, using the scraping plate to move the moved paste from the second end part to the first end part relative to the second end part, on the other hand, carrying out the second printing on the second semiconductor substrate by enabling the moved paste to pass the opening part; and roasting the printed paste to form an electrode of a specified pattern.

Description

technical field [0001] The present invention relates to a method of manufacturing a solar cell including a step of forming an electrode pattern by printing. [0002] This application claims the priority of Japanese Patent Application No. 2014-033997 for which it applied on February 25, 2014, The whole content of the application is taken in in this specification as a reference. Background technique [0003] In recent years, due to the enhancement of environmental awareness and from the viewpoint of energy saving, the popularization of solar cells (solar cells) has rapidly progressed. Along with this, there is a demand for a solar cell with a cell structure with higher performance than conventional ones, that is, a cell structure with good photoelectric conversion efficiency and high output. As one measure for realizing the above-mentioned requirements, there is a measure of enlarging the light-receiving area per unit area of ​​the solar cell. For example, as one method for ...
