Silicon Solar Cell Electrode Paste For Back Side SN928X

      LEED SN928X is an environmental conductive paste designed on silicon solar cell(n+) positive electrode.The conductive component in silver paste will be the excellent ohmic contact characteristics with silicon and have good compatibilities with back aluminium paste when co-fired.It has the features of good printing,low contact resistance,good solderability and weldability.

Data Sheet

Recommended Technical Information & Notice

Printing£ºIt is recommended the lustration grade of appliance and circumstance to be more than ten thousand degree, it should be guarantee that the room temperature and appliance temperaute remains 24¡À2¡æ during printing. Keep stir it slowly and fully before using. If take out of from icebox or icehouse firstly, please place it in the printing house until it return to room temperature.

Drying£ºIt can be dried both in infrared stove and rotary dry furnace, the peak temperature of drying is 250¡«300 degree centigrade, the drying time can be regulated according drying situation.

Firing£ºFiring is one of most imporant data for affecting the performance of paste.The firing need to use flash firing technics£¬the peak temperature can be regulated according the quality of fired thickness.

Thinning£ºThe composition is optimized for screen printing,and thinning is not normally required.In order of avoid the unnecessary losses,please use thinner more carefully,and stir fully after thinning

Compatibility£º It is therefore essential that customers thoroughly evaluate the material in their specific siuations in order to completely satisfy themselves with the overall quality and suitability of the composition for its intended applications.

Transportation and Storage£ºDuring transportation and storage should protect against the tide and contamination. Containers may be stored in a clean, dry and stable environment at room temperature (between 5¡æ¡«20¡æ),with their lids tightly sealed.
