What do you lay your solar cells on when Soldering?

That didnt help. And Im also using Kester SN63PB37

The problem is when I solder the front side. And get it all looking Nice.
I do the backside which totally destroys my solder work in the front of cell

I have been running into problems not sure if its becuase my heat is to high.

Im using Weller wes51

And When I solder the front side of cell at temp setting at 750 Degrees Fahrenheit
And then when I solder the back side at that heat. It then melts the other side of cell and makes my work look like cr@p. The front side melts when I do back side.

Im using just a thin piece of glass.

What do you use to solder on? Do I need a metal plate perhaps to keep cell cool when Soldering.

Any suggestions would help

Also the cells im soldering is Mono

I was soldering my other cells which are mono but they only produce 2.8w, they solder fine But I tried today to solder the higher wattage cells I have and its just melting the other side :\
