Patent ID: 8497154

Claim:
A solar cell system manufacturing method, the method comprises steps of: S 100 : providing a plurality of P-N junction cell preforms comprising M number of P-N junction cell preforms, M being greater than or equal to 2, the plurality of P-N junction cell preforms being labeled as a first P-N junction cell preform, a second P-N junction cell preform, so forth, and a Mth P-N junction cell preform; each of the plurality of P-N junction cell preforms comprises a first silicon preform, a second silicon preform stacked with the first silicon preform, a first surface of the first silicon preform away from the second silicon preform, and a second surface of the second silicon preform away from the first silicon preform; S 200 : arranging the plurality of P-N junction cell preforms from the first P-N junction cell preform to the Mth P-N junction cell preform along a straight line; S 300 : forming at least one inner electrode preform of carbon nanotubes between adjacent two of the plurality of P-N junction cell preforms, the at least one inner electrode preform comprising an array of carbon nanotubes comprising a plurality of carbon nanotubes, and axial directions of the plurality of carbon nanotubes in the array of carbon nanotubes being parallel to the straight line; S 400 : forming an inner electrode preform between remaining adjacent two of the plurality of P-N junction cell preforms; S 500 : forming a first collecting electrode preform on an outside surface of the first P-N junction cell preform and forming a second collecting electrode on an outside surface of the Mth P-N junction cell preform to obtain a solar cell system preform; and S 600 : cutting the solar cell system preform along the straight line to obtain a plurality of solar cell systems.
