Crystalline Silicone Solar Cell Back Side Silver Paste BY01
BY01 is an environmental conductive paste designed on silicon solar
cell back side electrode. The conductive component in silver paste
will be the excellent ohmic contact characteristics with silicon
and have good compatibilities with back aluminum paste when
co-fired. It has the features of good printing, low contact
resistance, good solderability and weldability. It is a high
performance back side silver paste.
- Good printing characteristics
- Low contact resistance
- High conductivity
- Excellent solderability
- Co-fireable with front side silver and back side aluminum
- Up to RoHS environmental regulation

Notice of Usage
Printing should be carried out in a clean, well-ventilated area,
which with cleanliness of no less than 100 thousand grade. It
should be guarantee that the printing room temperature remains
25±2℃ during printing.
The paste should be stirred fully before printing.
If take out from cold closet, the product should be placed in
printing room till it returned to room temperature before use.
If thinner added, it is essential to fully stir the paste for
ensure the performance.
Chain fast burning furnace:
280℃-350℃/20-50sec, drying time is flexible in accordance with
dryer type, but should not last long;
Rotating drying furnace:
Firing process is the key parameter affecting paste
It is advised to use flash burning process.
The firing peak temperature should be adjusted according to fired
film quality, solderability, weldability and solar cell electrical
