Effects of Sheet Resistance on mc-Si Selective Emitter Solar Cells Using Laser Opening and One-Step Diffusion

Figure 8

(a) Comparison of contact resistance (mΩ-cm²) with the average percentage of occupied surface minority carriers (%) for six SE samples and (b) corresponding real-distribution maps of contact resistance profiles. The left-down point is the origin of - coordinates which means the scan size of cells, from 0 to 1500 (extreme = 1550) with interval of 100, and scale is mm/10. The right -axis (color chart) represents resistance values (in mΩ-cm²), from bottom (0 for dark purple) to top (40 for bright red) with interval of 2.
