Embodiment

[0051] Next, embodiments of the present invention will be described in detail.

[0052] In the following examples, the same silver paste was used to form the sub-gate electrode 5 , and the silver paste used to form the main gate electrode 4 was variously changed, and its characteristics were investigated. The silver paste used to form the sub-gate electrode 5 was used as a reference silver paste. In addition, all the silver pastes used in the following examples have burn-through properties.

[0053]

[0054] In the first to fourth examples, the solar cells of the first to fourth examples were produced using silver pastes having different silver content and glass frit content in the silver paste used for forming the busbar electrode 4 . Also, in the first to fourth embodiments, as described above, the sub-gate electrode 5 is formed using the reference silver paste. In addition, as a reference, a reference solar cell in which both the main grid electrode 4 and the sub-gate e...

Abstract

Provided are a solar cell fabrication method and a solar cell in which the degree of inclusion of silver in a silver paste which is used in forming a substrate surface main grid electrode is made lower than the degree of inclusion of silver in the silver paste which is used in the formation of a sub-grid electrode.

Description

[0001] This application is a divisional application of an invention patent application with an application date of December 27, 2012, an application number of 201280066671.7 (international application number is PCT / JP2012 / 083805), and an invention title of "solar cell manufacturing method and solar cell" . technical field [0002] The present invention relates to a method for manufacturing a solar cell and the solar cell. Background technique [0003] In recent years, expectations for a solar cell that directly converts solar energy into electrical energy as a next-generation energy source have been rapidly increasing, especially from the viewpoint of global environmental protection. There are various types of solar cells such as solar cells using compound semiconductors and organic materials, but solar cells using silicon crystals are currently the mainstream. [0004] Currently, the structure of the most manufactured and sold solar cells is a structure in which electrodes...
