Embodiment

[0031] In the following, the embodiments of the present application have better photoelectric conversion efficiency than conventional conductive pastes.

[0032] Composite glass frit preparation

[0033] 1. Preparation of the first type of sub-frit

[0034] The first type of sub-glass frit mainly includes lead oxide compound and silicon oxide compound, and the first type of sub-glass frit sample is prepared according to the composition ratio in Table 1 below.

[0035] 【Table I】

[0036]

[0037]It can be seen from Table 1 that the glass transition temperature (Tg) and glass softening temperature (Ts) of the first type of sub-glass frit samples range from 357°C to 391°C and from 371°C to 421°C, respectively.

[0038] 2. Preparation of the second type of sub-frit

[0039] The second type of sub-glass frit mainly includes tellurium oxide compound and zinc oxide compound, and the second type of sub-glass frit sample is prepared according to the composition ratio in Table 2 b...

Abstract

The present invention relates to a conductive paste and a method for producing solar cell by using the same. The conductive paste comprises at least silver powders and a composite glass frit comprising a first type of glass frit containing lead oxides and silicon oxides and a second type of glass frit containing tellurium oxides and zinc oxides wherein the first type of glass frit and the second type of glass frit are in a weight ratio of 93:7 to 44:56.

Description

technical field [0001] The application belongs to the field of conductive paste, and in particular relates to a conductive paste capable of improving the conversion efficiency of solar cells and a method for manufacturing solar cells using the same. Background technique [0002] Conductive paste is an indispensable product for today's electronic products. For example, the manufacture of solar cells, glass lamp panels, and flat-panel displays requires the use of conductive paste. Therefore, how to achieve good power transmission and reduce power transmission loss is easy. It is the basis for judging whether the conductive paste is good or not. [0003] In the manufacture of solar cells, conductive paste is the main material of crystalline silicon solar cells. In the process of solar cell production by screen printing, the general paste screen printing sequence is to first print silver and aluminum paste, dry, and then print aluminum paste, Drying, finally printing silver pas...
