Solar cell system manufacturing method

A solar cell system manufacturing method, the method comprises steps of:

• S100:
• providing a plurality of P-N junction cell preforms comprising M number of P-N junctions cell preforms, 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, . . . , and a Mth P-N junction cell preform, each of the plurality of P-N junction cell preforms comprising a first silicon preform and a second silicon preform stacked with the first silicon preform;
• S200:
• 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;
• S300:
• forming an array of carbon nanotubes between each adjacent two of the plurality of P-N junction cell preforms, the array of carbon nanotubes comprising a plurality of carbon nanotubes, axial directions of the plurality of carbon nanotubes in the array of carbon nanotubes being parallel to the straight line;
• S400:
• forming a first collecting electrode preform on an outside surface of the first P-N junction cell preform and forming a second collecting electrode preform on an outside surface of the Mth P-N junction cell preform to obtain a solar cell system preform;
• and
• S500:
• cutting the solar cell system preform along the straight line.
