Method for making solar cell and solar cell system |
摘要 |
A solar cell making method includes steps of making a round P-N junction preform by (a) stacking a P-type silicon layer and a N-type silicon layer on top of each other, and (b) forming a P-N junction near an interface between the P-type silicon layer and the N-type silicon layer, wherein the round P-N junction preform defines a first surface and a second surface; forming a first electrode preform on the first surface and forming a second electrode preform on the second surface, thereby forming a round solar cell preform; and forming a photoreceptive surface with the P-N junction exposed on the photoreceptive surface by cutting the round solar cell preform into a plurality of arc shaped solar cells, the photoreceptive surface being on a curved surface of the arc shaped solar cell and being configured to receive incident light beams. |

1. A solar cell making method, comprising steps of:
S11, making a round P-N junction preform by (a) stacking a P-type silicon layer and a N-type silicon layer on top of each other, and (b) forming a P-N junction near an interface between the P-type silicon layer and the N-type silicon layer, wherein a surface of the P-type silicon layer away from the N-type silicon layer is defined as a first surface, and a surface of the N-type silicon layer away from the P-type silicon layer is defined as a second surface; S12, forming a first electrode preform on the first surface and forming a second electrode preform on the second surface, thereby forming a round solar cell perform comprising the first electrode preform, the P-type silicon layer, the N-type silicon layer, and the second electrode preform arranged in the above sequence; and S13, forming a photoreceptive surface with the P-N junction exposed on the photoreceptive surface by cutting the round solar cell preform into a plurality of arc shaped solar cells, the photoreceptive surface being on a curved surface of the arc shaped solar cell and being configured to receive incident light beams. |
