Solar cell and method for fabricating the same
A high-efficiency solar cell structure enables high throughput manufacturing process thereof. The solar cell (10, 20, 30) is accomplished by forming a plurality of first emitter regions (12, 22, 32) in a front surface of a substrate (11, 21, 31), a plurality of second emitter regions (13, 23, 33) in...

| Zusammenfassung: | A high-efficiency solar cell structure enables high throughput manufacturing process thereof. The solar cell (10, 20, 30) is accomplished by forming a plurality of first emitter regions (12, 22, 32) in a front surface of a substrate (11, 21, 31), a plurality of second emitter regions (13, 23, 33) in the front surface, and a plurality of fingers (14, 24, 34). Each of the fingers (14, 24, 34) is formed over a least a portion of the second emitter regions (13, 23, 33) and a portion of the first emitter regions (12, 22, 32). The first emitter regions (12, 22, 32) and the second emitter regions (13, 23, 33) have a depth not less than 0.2 µm. |
