INSPIRED INNOVATION

u In-Line Rapid Thermal Shock

Removes bow from cells below 180 micron
eliminating the need for low-bow paste

The In-line Rapid Thermal Shock (IL-RTS) tool leverages proven
Despatch thermal technology from the electronics industry for
a revolutionary solar application. The IL-RTS features a simple,
in-line process that removes wafer bow by rapidly heating the
wafer after cooling, eliminating the need for higher-cost, lower

efciency low-bow paste.

After moving through the ring furnace, cells enter the

IL-RTS and are rapidly cooled to stabilize any thermal stresses.
Following the cooling, cells are returned to a temperature above
the dew point temperature to prevent condensation. The IL-RTS

is designed to be compatible with any ring furnace on the front

end, and the exit table accepts cell tester automation equipment
for a completely seamless in-line process.
