Production steps of crystalline silicon solar cells include several physical and
chemical processes like etching, doping, annealing, nitride coating,
metallization and firing of the metal contacts. Among these processes, the
metallization plays a crucial role in the energy conversion performance of the
cell. The quality of the metal layers used on the back and the front surface of
the cell and the quality of the electrical contact they form with the underlying
substrate have a detrimental effect on the amount of the power generated by
the cell. All aspects of the metal layer, such as electrical resistivity, contact
resistance, thickness, height and width of the finger layers need to be
optimized very carefully for a successful solar cell operation.
In this thesis, metallization steps within the crystalline silicon solar cell
production were studied in the laboratories of Center for Solar Energy
Research and Application (GÜ / NAM). Screen Printing method, which is the
most common metallization technique in the industry, was used for the metal
layer formation. With the exception of the initial experiments, 6
