Assessing the impact of multi-busbars on metallization cost and ...
The cost of solar electricity can be reduced through the use of less silver ink. This can be achieved by alternative printing technology - the inkjet-printing. In this paper we report on a two-diode model for the gridline design optimization of a 19.2% efficiency inkjet-printed silicon solar cell. The model showed that, the multi-busbar design has less dependence on …
