Multi-busbars aid in the reduction of internal resistance losses, which occur due to the shorter distance between the busbars. In a typical solar cell, the metallization pattern usually has thin silver fingers that are responsible for current collection and transportation to the thick busbars.
a front design with three busbars. This offers the poss i bility to reduce the amount of metal needed for the front side metallization. In Fig. 4 one can observe a rapid ri se of the area weighted series resistance of the front grid of a 3-busbar solar cell with decreasing fi nger width. In contrast, for the wire solar cell the
The multi-busbar solar cell is optimized for module integration. This can be observed taking a look at the fill factors of the modules. The average fill factor of the 3-busbar modules is in the range of 76.7%, w von Campe H, Huber S, Meyer S, Reif S, Vietor J. Direct tin-coating of aluminum rear contact by ultrasonic soldering.
In the solar cell, there is a thin rectangular strip printed on front and backside of the solar cell to conduct electricity, that strip is called a busbar.
A detailed simulation of a screen printed and stringed rear side of a multi-busbar solar cell revealed the amount of rear side pads necessary for a sufficient interconnection leading to low series resistances. Simulated cell efficiency plotted over the number of busbars. The black line shows the device contacted with multiple pins on busbars.
The assumed busbar width is 1.5 mm. F or the contribution of the series resistance one has to add all components of a solar cell as described in . 5]. The diameters. Line and contact resistance for the screen printed metal f ingers were determ ined by fou r point probe measurem ents of comparable solar cells [ 6 ].
