It has been found, in these studies, that the front metal grid design has a great impact on the solar cell electrical performance. The losses associated with the grid influence directly the conversion efficiency of solar cells , , , .
Griddler 2.5 was utilized as the tool in this investigation to simulate the SHJ solar cells with different front grid arrangements. A variety of input parameters were employed in the simulation. This simulation tool was chosen because it has an integrated interface for designing front H-patterns and back metal grids.
These solar cells were designed with a grid on the front, by varying the number of fingers, style, finger width, and busbar endings. The rear designs of the busbars employed 5 busbars, 4 probe (solder) points, and a constant busbar width of 0.12 mm for the entire study.
As a result, efforts are now directed to the production of these cells. In this sense, the use of frontal metal grids in large-area perovskite cells and parallel-connected modules is imperative due to the low conductivity of the transparent conductive substrate usually employed in these devices.
The finite-element method (FEM) is applied in solar cell modeling to approximate the cell plane as a network of resistors and diodes. It also features an interface for generating H-patterns and back metal grids.

The achievement of high efficiency in solar cells is depended upon minimizing parasitic losses. Some fraction of the power produced by the cell is necessarily l.
These fine electrodes do not create any obstruction in the pathway of the light to reach the thin p-n junction. A current-collecting electrode is also placed at the bottom of the n-type layer. Another thing about the construction and working of solar cells is that the manufacturers encapsulate the assembly using thin glass. This helps to prevent mechanical …
