Quantification of Power Losses of the Interdigitated Metallization of Crystalline Silicon Thin-Film Solar Cells on Glass

Figure 3

A sample unit cell within an interdigitated thin-film solar cell. The lighter grey areas correspond to emitter (busbar and finger) features, the dark grey areas correspond to BSF features, and the external contact lead is shown in black. 𝐴 is the distance from the edge of the cell to the external contact lead.
