YS/T 612-2014Paste for solar cells (English PDF)

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

Instead of the standard YS/T 612-2006 "solar cell paste." Compared with this standard YS/T 612-2006, the main changes as follows.

--- The solids content of the front side silver paste, silver paste and aluminum paste on the back from 80% to 88%, 75% to 85%, 65% and 80%, respectively Changed from 86% to 92%, 45% to 70%, 70% to 80%;

--- The fineness of the front side silver paste, silver paste and aluminum paste on the back of the original <=15µm, <=20µm, <=80µm were changed <=10µm, <=15µm, <=25µm;

--- The front side silver paste, silver paste and aluminum paste on the back of the original viscosity of 20Pa · s ~ 100Pa · s, 20Pa · s ~ 100Pa · s, 150Pa · s ~ 450Pa · s were changed to 260Pa · s ~ 750Pa · s, 35Pa · s ~ 80Pa · s, 15Pa · s ~ 50Pa · s;

--- Increasing the viscosity determination when setting conditions;

--- Increasing the drying temperature front side silver paste, silver paste and aluminum paste on the back of three kinds of slurry and drying time;

--- The firing temperature front side silver paste, silver paste and aluminum paste on the back of the original 720 °C ~ 780 °C, 650 °C ~ 700 °C, 600 °C ~ all 700 °C to 760 °C ~ 830 °C;

--- Increase the adhesion of the aluminum paste was measured after sintering warpage measurement and boiled.

This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized.
