The Solar Panel Sintering Tunnel Furnace is a core thermal processing equipment used in photovoltaic cell production lines. It adopts infrared radiation heating or microwave heating technology to rapidly heat and cool silicon wafers printed with front and rear electrode pastes. This process enables the formation of excellent ohmic contact between the metal paste and silicon wafer, directly affecting the electrical conversion efficiency of solar cells.

Applications

Front Silver Paste Sintering:

Used to form front grid electrodes for efficient current collection and photovoltaic power output.

Rear Aluminum Paste Sintering:

Used to form the back surface field (BSF), reducing minority carrier recombination.

Rear Silver Paste Sintering:

Used to form rear busbar electrodes for subsequent welding processes.
