The tubes were placed between two glass slides and were clamped. 500g was placed over the slides and then cap wasremoved. The amount of the extruded paste was collected and weighed.

Conductive copper paste is a promising material for use in electronic devices, replacing silver or other metal pastes, because of its high conductivity, low electro-migration, and cost. However, the high sintering temperature and the need of an inert sintering atmosphere limit the commercial application of copper paste. In this study, a copper thick film paste for use on

Typical commercial formulations of screen-printing pastes for front-side metallization consist of conductive material (85–90 wt%), i.e. micron sized spherical silver particles x 50 ≈ 1–3 μm, dispersed in a continuous phase (5–14 wt%), the so-called vehicle. This is a mixture of organic solvent containing non-volatile organic binders and additives to control
Since the silver paste plays a major role in the mass production of silicon solar cells, this work has succeeded in optimizing the silver paste in 80–85 wt.% and optimizing its particle size in 1–1.5 μm spherical powder. As the firing temperature is increased, the growth trend of silver grain is improved.

These finding can suggest that boron content in aluminum pastes is supportive to improve the bulk quality of silicon solar cells. However, poor performance of such pastes on solar cell fabrication is needed to be investigated further for higher efficiencies. 1.
Solar cells with developed aluminum pastes show better performance than that of the cells with C-Al-paste. Pseudo efficiency of the cells with B-free-Al-paste and Al-B-paste BSFs were 18.3% and 18.0%, respectively. Table 3.
The dispersed boron can be diffuse towards the front side of silicon solar cells which can deteriorate the photovoltaic properties. It is important to consider this phenomenon in further studies in order to improve the performance of silicon solar cells using boron-doped aluminum pastes.
Carrier lifetimes of the wafers processed by Al-B-paste maintained at around 300 μ s relatively higher than the wafers processed by B-free-Al-paste. P-type silicon solar cells were fabricated using developed pastes and were compared with those of the cells fabricated by commercial aluminum pastes.
Conclusion Screen printable aluminum pastes with and without boron content were introduced in this work for crystalline silicon solar cells. Both pastes provided high carrier lifetimes after alloying by thermal processing.
In case of boron included aluminum pastes, besides increasing the alloying concentration, addition of boron content into the aluminum can alter the gettering effect at the same time. However, production of such a paste and adaptation of it to the silicon solar cells is necessary.
