pleased to offer the entire line of PV and PVD
series furnaces from Radiant Technology Corporation (RTC).
RTC, the first name in infrared furnace solutions, has incorporated 35
years of experience and know-how into this Rapid Thermal Processing (RTP)
line of furnaces. Specifically designed for solar cell applications such
as contact drying/firing and metallization.
BENEFITS AND FEATURES
achieved with a higher density of IR lamps in smaller temperature
zones. Heat up rates can exceed 75 °C per second between 400
°C and 875 °C.
is achieved with
water-cooled cold walls above and below the conveyor belt. the cold
walls are separated from the last heated zone by a 12 cm transition
tunnel with CDA-fed curtain and baffles. Cool down rates can exceed 65
°C per second between 875 °C and 400 °C.
FAST BELT SPEEDS TRANSPORT
which carry lightweight solar
cells smoothly. Belt vibration is minimized with a friction drive
roller. Optional dimpled belts enable faster heating and cooling by
reducing solar cell contact with the conveyer belt.
with a laminar flow
of pre-heated gas produces a broad process window. Clean dry air (CDA)
is fed into the heating chamber through the top and bottom porous
ceramic walls (RTC patent).

The contact firing and metallization
application is used in the manufacturing of solar cells. It involves the
process by which thickfilm conductive inks (usually silver and aluminum)
are applied to the front and back side of the solar cell. After the
solar cell has been doped and an anti-reflective coating has been
applied, the cell will have conductive material dispensed, screen
printed or spot printed onto it. The material will be dried and
subsequent layers are added using the same method. The final step is to
fire the solar cells in a rapid thermal processing environment, ranging
in temperature from 780 °C to 900 °C.
BTU offers the RTC line of near infrared lamp furnaces to handle the
rapid heating tasks of this application. This is an in-line continuous
furnace designed for rapid thermal processing.
