Abstract

A solar cell can include a substrate of a first conductive type; an emitter layer of a second conductive type opposite the first conductive type, and positioned on the substrate; a plurality of finger electrodes formed in a first direction, each finger electrode being electrically connected to the emitter layer; a plurality of first collector regions; a plurality of first electrodes positioned in a plurality of first collector regions and extending in the first direction from the plurality of finger electrodes; a plurality of second electrodes positioned in the plurality of first collector regions and formed in a perpendicular direction crossing the first direction; a plurality of third electrodes positioned in the plurality of first collector regions, connecting two neighboring first electrodes of the plurality of first electrodes and formed in the perpendicular direction; and a plurality of deletions positioned in the plurality of first collector regions. Furthermore, one of the plurality of second electrodes is positioned between a pair of the plurality of first electrodes.

Claims (22)

1. A solar cell comprising:

a substrate of a first conductive type;

an emitter layer of a second conductive type opposite the first conductive type, and positioned on the substrate;

a plurality of finger electrodes formed in a first direction, each finger electrode being electrically connected to the emitter layer;

a plurality of first collector regions formed in a second direction crossing, the first direction, wherein the plurality of first collector regions include a plurality of first electrodes extending in the first direction from the plurality of finger electrodes and having a space of a predetermined distance from each other positioned in parallel in the second direction, and a plurality of second electrodes positioned between the space of the plurality of first electrodes in the second direction and two neighboring second electrodes of the plurality of second electrodes positioned in a different space in the plurality of first collector regions; and

a plurality of deletions positioned in the plurality of first collector regions,

wherein one of the plurality of deletions is positioned in an area of one first collector region of the plurality of first collector regions formed only by a pair of first electrodes of the plurality of first electrodes, and one second electrode of the plurality of second electrodes.

2. The solar cell of claim 1 , wherein one electrode of the pair of first electrodes is positioned at an upper end of the one deletion and the other electrode of the pair of first electrodes is positioned at a lower end of the one deletion opposite the upper end of the one deletion.

3. The solar cell of claim 2 , wherein the one second electrode is positioned at a left end of the one deletion or at a right end of the one deletion opposite the left end of the one deletion.

4. The solar cell of claim 3 , wherein opposite ends of the one second electrode are connected to the pair of first electrodes, respectively.

5. The solar cell of claim 1 , wherein the pair of first electrodes and the one second electrode form a first collector, and

wherein the first collector connected to the pair of first electrodes and the one second electrode has a -shape.

6. The solar cell of claim 5 , wherein the plurality of deletions are rectangular.

7. The solar cell of claim 1 , wherein one of the plurality of second electrodes are disposed in a first vertical line along a perpendicular direction crossing the first direction, other of the plurality of second electrodes are disposed in a second vertical line along the perpendicular direction crossing the first direction, and the first vertical line and the second vertical line are different vertical lines positioned non-collinearly along the perpendicular direction crossing the first direction.

8. The solar cell of claim 1 , further comprising:

a back electrode electrically connected to the substrate; and

at least one second collector region connected to the back electrode.

9. The solar cell of claim 8 , wherein an area formed by linearly connecting in a perpendicular direction both lateral sides of at least one of the at least one second collector region comprises at least one deletion, and

wherein the at least one deletion is positioned in a portion of the at least one second collector region lacking an electrode.

10. The solar cell of claim 1 , wherein the pair of first electrodes and the one second electrode form a second collector, and

wherein the second collector is connected to the pair of first electrodes and the one second electrode.

11. The solar cell of claim 10 , wherein the plurality of deletions are rectangular.
