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

Figure 4

A sample unit cell of an interdigitated thin-film solar cell. 𝐶 is the total cell width, 𝑊_𝐸 is the emitter busbar width, 𝐵 is the emitter/BSF finger length, 𝑊_𝐴 is the BSF busbar width, 𝑆 is the (centre-to-centre) emitter finger spacing, and 𝑊_𝐹 is the emitter finger width.
