Thick Film Processing
After a paste is screened onto a substrate and it settles for 5–15 minutes at room temperature, it undergoes oven drying at 100-150°C for 10–15 minutes to remove solvents. Firing is then completed in conveyor belt furnaces at temperatures between 500-1000°C.
Crystalline Silicon Solar Cell Manufacturing
Electrical contacts are usually formed by screen printing. The firing is done in conveyor belt furnaces at a temperature of about 700°C for a few minutes. Upon firing, the organic solvents evaporate and the metal powder becomes a conducting path for the electrical current.
Thin Film Solar Cells Manufacturing
A transparent conducting glass, coated with doped SnO2 or ITO film, is used as a substrate. A thin film, such as CdS, is then deposited through CSS or CBD techniques. The CdS film is heat treated by a conveyor belt furnace in a reducing atmosphere or in the presence of CdCl2 at 400-500°C.

Dye Sensitized Solar Cells (DSSC) Manufacturing
TiO2 nanoparticles have been used extensively to increase the interfacial surface area in Dye Sensitized Solar Cells. Nanoparticle films are generally made by screen printing a paste of titania nanocrystals and then sintering the particles together at 450-500°C in a conveyor belt furnace.
