Energy is one of the main problems of this new millennium. The photovoltaic electricity should have a significant role in the future energy mix.
At an industrial scale, the front side metallization of silicon solar cells is performed by screen printing of a silver paste. This step is critical in production lines because it determines both their cost and their final performance. Consequently, it is necessary to limit the amount of printed silver paste while maximizing the cell efficiency.
The first part of this work is focused on the effects of the printing parameters on these two crucial aspects. To ensure the photovoltaic industry growth, the screen printing process should be replaced in coming years. The seed and plate concept is an innovative solution during which a first layer is printed and thickened by plating. Thanks to its flexibility and low pressure during printing, the flexographic printing process seems particularly well suited to meet the seed layer requirements at an industrial level. The second part of this work focuses on the development of this printing technique.
