The specific technological objectives of the current program are to identify and characterize suitable metallo-organic (MO) compounds, develop generic synthesis procedures for the MO compounds, develop generic fabrication procedures for screen printable metallo-organic decomposition (MOD) silver inks, and optimize processing conditions to produce grid patterns on photovoltaic cells. The metallizations will be evaluated as to their appearance, line definition, adhesion, sheet resistance and microstructure. The metallized cells will be evaluated at JPL as to their performance as solar cells, although initial photovoltaic evaluation will be done at Purdue. Once a suitable MOD silver ink or inks have been developed a small weight percent (<5 w/o) of a suitable platinum MO compound will be added to give the ink good solder leach resistance which silver films alone do not possess. The platinum addition will also allow for quantitative adhesion data to be collected. Other additives in the form of MO compounds may also be used should a permanent binding agent be deemed necessary. Once a final ink composition is selected, the metallizations adhesion and sheet resistance will be evaluated after thermal aging. Another objective of the program is to develop a model which describes the adhesion between the fired silver film and the silicon surface.
