Problems solved by technology

However, while people are pursuing the goal of "narrow and thick", new problems have emerged. The design of small-sized thin grid lines requires too high a bridge size between the thin grid lines, that is, it is necessary to design bridges with sufficiently small wire diameters. connected, while small wire diameters are prone to breakage during printing
That is, during the use of this type of solar electrode printing screen, its service life is severely limited

Embodiment Construction

[0023] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] to combine figure 1 and figure 2 , figure 1 It is a structural schematic diagram of a solar cell electrode grid without auxiliary grid lines in the prior art. The grid is an electroformed grid, usually an electroformed nickel grid. and figure 1 compared to figure 2 The embodiment of the present invention provides a solar cell electrode printing screen with auxiliary grid lines 30, the printing screen 1 is provided with a plurality of auxiliary grid lines 30; the auxiliary grid lines 30 are parallel to the solar cell electrode printing screen The fine grid lines 10. In this embodiment, after a plurality of auxiliary grid lines 30 are added to the solar cell e...

Abstract

The invention relates to the technical field of solar batteries and discloses a solar battery electrode printing screen with auxiliary grid lines. A plurality of auxiliary grid lines are arranged on the solar battery electrode printing screen, and the auxiliary grid lines are parallel to thin grid lines on the solar battery electrode printing screen. After the auxiliary grid lines are added on the solar battery electrode printing screen, line breaking rate of the thin grid lines of the solar battery electrode printing screen is greatly reduced, corresponding increase of electroforming printing times can be achieved, namely service life of the printing screen is prolonged, and accordingly printing cost can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a solar cell electrode printing screen with auxiliary grid lines. Background technique [0002] At present, non-renewable energy sources such as electricity, coal, and petroleum are frequently running out. Energy issues have increasingly become a bottleneck restricting the development of the international society and economy. More and more countries have begun to implement the "Sunshine Plan" to develop solar energy resources and seek new impetus for economic development. As a core technical content of solar energy research, solar cells have developed rapidly in recent years, and the demand for higher conversion rates has also increased the requirements for solar cell electrodes. Among them, the thin grid lines of positive electrodes are "narrow and thick" The goal is also of great concern. However, while people are pursuing the goal of "narrow and thick", new problems have ...
