What is photovoltaic (PV) technology and how does it work? PV materials and devices convert sunlight into electrical energy. A single PV device is known as a cell. An individual PV cell is usually small, typically producing about 1 or 2 watts of power. These cells are made of different semiconductor materials and are often less than the thickness of four human hairs.
The grid line of a solar cell is an important component of the metal electrode on the front of the solar cell. Its main function is to collect and transmit photo generated charge carriers, thereby achieving solar energy conversion.
Why do photovoltaic panels have grid lines? The grid lines found on the surface of photovoltaic panels serve as electrical conductors. They are responsible for collecting the electricity generated by the individual solar cells and guiding it

The shape of grid lines or fingers, used to reduce conductive losses in photovoltaic cells, is shown to be optimized while the current flux in the line remains constant. This result is derived for cells of arbitrary geometry. There is an analytical way to achieve almost the best pattern, but a necessary assumption forces us to keep the fraction
This current is extracted through conductive metal contacts – the grid-like lines on a solar cells – and can then be used to power your home and the rest of the electric grid. The efficiency of a PV cell is simply the amount of electrical
A solar cell, also known as a photovoltaic cell (PV cell), is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect. [1] It is a form of photoelectric cell, a device whose electrical characteristics (such as current, voltage, or resistance) vary when it is exposed to light.. Individual solar cell devices are often the electrical

The five-busbar SG–UEB combination results in efficiency above 20% for industrial-sized solar cell without an additional step or layer. The improvement in the cell efficiency obtained using the uneven busbar design is attributed not only to the decreased shading but also to reduced contact recombination underneath the busbars.

The shading area of the photovoltaic welding strip is reduced by reducing the width of the main grid line and the PV welding strip, and the total amount of light received by the solar cell is increased. However, the contact resistance of the whole PV assembly is too large, which increases the electrical loss of the photovoltaic module. Therefore, the optimization of
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.
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.

Because of the nonuniformity and porosity of the printed metal gridlines and busbars, and the nonrectangular cross-sectional shape of the gridlines (Fig. 2 ), the assumptions made in those grid models disagree with the metal grids printed in practice.
The efficiency of the modeled three- and five-busbar solar cells as a function of s for the continuous gridlines and the gridlines with the optimal segmentation (with minor busbar width of 0.6 mm) As s is decreased from 1 to 0, the average busbar width shrinks due to the reduction in the total major busbar length.
