Definitions
- the invention relates to a solar cell with special Busbar form, a solar cell array containing this solar cell and a method for producing the solar cell.
- Solar cells generally consist of a layer structure which is formed in a plate-shaped semiconductor material, for example monocrystalline or multicrystalline silicon.
- the semiconductor material forms the p-type base.
- a thin n-type layer By diffusion of phosphorus, a thin n-type layer, the so-called emitter, is produced on the surface.
- the base is contacted by means of a full-surface applied aluminum layer.
- the emitter is contacted via narrow fingers, which are interconnected by one or more so-called busbars. Since the metallic fingers and busbars do not allow light to enter the contacted areas of the cell, but increase the number and width of fingers but the series resistance, the fingers and busbars must be designed so that electrical losses and shadowing losses are minimized.
- the area between point P1 and point P3 and the area between point P2 and P4 are substantially linear.
- essentially linear means that the magnitude of a slope of a straight line at point P3 and at point P4 is preferably somewhat lower than at point P1 or P2, so that, starting from P1, the width of the current collecting region preferably first decreases linearly, which is in the range around point P2 connects a curved area, after which the width of the current collecting area in turn increases linearly to the next contact pad.
- the invention also relates to a solar cell arrangement, in which at least two of the solar cells described above are electrically conductively connected to each other by a first busbar is connected on a first solar cell by means of a contact strip with a second busbar on an adjacent solar cell.
- FIG. 2 shows a side view of a solar cell arrangement according to the invention, in which three solar cells are electrically interconnected in series.
- FIG. 3 shows a plan view of a solar cell according to the invention with three busbars in which contact islands are connected to each other by means of current collecting areas along a connecting line.
- a current collecting region 10 on the connecting line 8 which contacts the contact islands 9, 9' in a contact region 11, wherein the contact region 11 has two outer points P1 and P2 on both sides of the connecting line 8, the distance perpendicular to the connecting line 8 a maximum width b Smax of Current collection area 10 defined, where b
- the width b of the current collecting region 10 decreases starting from a contact pad 9 to an adjacent contact pad 9 'initially to a minimum width b Sm in between two inner points P3 and P4 and then to the adjacent contact pad. 9 'back to a maximum width bs max ' too.
