To optimize the grid pattern in terms of the solar cell efficiency, different grid models [ 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17] have been developed to assess the total series resistance and its components corresponding to the emitter, gridline, busbar, and contact.
Gridline segmentation combined with an uneven busbar concept is investigated. This is a low-cost pathway to achieving industrial solar cells with energy conversion efficiency above 20% without any additional cost.
The shape of grid lines or fingers, used to reduce conductive losses in photovoltaic cells, is shown to be optimized when the current flux in the line remains constant. This result is derived for cells of arbitrary geometry assuming the fraction of the cell area shaded is small. The shapes of grid lines for three special cases are provided.
The short-circuit current and front shading of the modeled three-busbar solar cell as functions of the minor busbar width (2 w2) for the continuous gridlines with s = 0.3, 0.4, and 0.5
Chen et al. [ 4] showed that, for a given number of busbars, the gridline height has a negligible impact on the cell conversion efficiency after it reaches a certain value. This suggests that the aspect ratio of the gridlines should also be optimized to design cost-effective solar cells.
Lehovec and Fedotowsky [l] have derived a relationship for grid spacing to minimize shading and sheet resistance losses, and Serreze provides a technique for minimizing shading and ohmic losses in grid lines of predetermined shape.
