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.
L. Wen et al. had studied the optimization of design for the two-grid structure in concentrator solar cells (2010). The influence of metal grid lines and power loses under concentrated sunlight in the optimization of grid contact design has been shown by Lee and Rao (2016). M. S.
Solar cell performance is highly dependent upon the front contact grid design for minimizing the power losses due to shading (optical loss) and for proper collection of the photo-generated charge carriers (electrical loss).
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.
The front grid designs of the above-mentioned solar cells consist patterns on busbars. There are some hollow structures in the busbars in Cell 1, Cell 2, and Cell 4 and some rectangular shaped openings in the busbar in Cell 3. Due to these patterns on the busbars the area consumed by the busbars are less which corresponds to less shading losses.
However, if the widths of the grid lines are decreased then the resistive losses will increase which in turn increase the electrical power loss. So, for optimization of the grid design these electrical and optical power losses must be balanced to produce minimum total power loss.
