Title: ANTI-AGING BACK SILVER PASTE FOR CRYSTALLINE SILICON SOLAR CELL, AND PREPARATION METHOD THEREFOR
Abstract:
An anti-aging back silver paste for a crystalline silicon solar cell, and a preparation method therefor. The anti-aging back silver paste for a crystalline silicon solar cell consists of the following components in parts by weight: 40 to 50 parts silver powder, 1 to 10 parts of nano-copper powder, 2 to 10 parts of lead-free glass powder, 35 to 55 parts of organic binder, and 1 to 5 parts of other additives. The preparation method comprises the following steps: preparation of an organic binder, preparation of lead-free glass powder and preparation of an anti-aging back silver paste material. By means of the anti-aging back silver paste for a crystalline silicon solar cell, a formed electrode film layer is compact, welding performance is good, and an anti-aging advantage is provided.
