Problems solved by technology

However, too thin electrode network wires are likely to cause disconnection, or increase the resistance and reduce the conversion efficiency of solar cells. Therefore, how to achieve thinner wires without reducing the overall power generation efficiency of the battery is the technical focus of this field.

Embodiment Construction

[0018] Herein, the present invention will be described in detail with respect to specific embodiments and viewpoints of the present invention. Such descriptions are for explaining the structure or step flow of the present invention, and are used for illustration rather than for limiting the claims of the present invention. Therefore, in addition to the specific and preferred embodiments in the description, the present invention can also be widely used in other different embodiments.

[0019] The present invention provides a conductive paste that can improve the conversion efficiency of solar cells. In an embodiment, it can be used to form the front electrode (ie, the light-receiving surface) of the solar cell substrate. The conductive paste proposed by the invention can be sintered at a low sintering temperature, so that the finished solar cell has high conversion efficiency. Hereinafter, an example is used to describe the implementation of the present invention, but the appli...

Abstract

The present invention discloses a conductive paste for solar cell, including the following composition: silver particle and two glass frits. A glass frit (I) comprises bismuth oxide, tellurium oxide, tungsten oxide, silicon oxide, and zinc oxide; and a glass frit (II) comprises lead oxide, tellurium oxide, and zinc oxide. The conductive paste is utilized to form the electrode of the substrate for solar cell to enhance the performance of Ohmic contact, fill factor and conversion efficiency of the solar cell, after sintering.

Description

technical field [0001] The present invention relates to a conductive paste, in particular to a conductive paste for improving the conversion efficiency of solar cells. technical background [0002] The solar power generation industry is an emerging industry full of development prospects, and has gradually emerged from the energy concept industry. At present, the international oil price is soaring, the global oil resources are limited, and the environmental protection awareness of the Kyoto Protocol on the reduction of waste gas is rising, which limits the traditional power generation methods such as burning oil and coal. Therefore, in recent years, major countries in the world have been actively researching and developing clean renewable energy to replace fossil fuel power generation, so as to alleviate the pollution problems caused by traditional power generation methods. Among the alternative energy sources, whether it is solar energy, wind energy, geothermal energy, biom...
