1. A solar cell system comprises:
a plurality of P-N junction cells comprising M number of P-N junction cells, wherein the M is equal to or greater than two, the plurality of P-N junction cells are arranged from a first P-N junction cell to an Mth P-N junction cell along a straight line and electrically connected to each other in series, and each of the plurality of P-N junction cells comprises a first silicon layer and a second silicon layer arranged side by side and in contact with each other; an inner electrode located between each adjacent two of the plurality of P-N junction cells, wherein a number of the inner electrodes is M−1, at least one of the inner electrodes comprises a plurality of carbon nanotubes, and each of the plurality of carbon nanotubes is curved and extends from one of the plurality of P-N junction cells to another one of the plurality of P-N junction cells, which is adjacent to the one of the plurality of P-N junction cells, to form a curved line; a first collecting electrode located on an outside surface of the first P-N junction cell; a second collecting electrode located on an outside surface of the Mth P-N junction cell; and a photoreceptive surface configured to directly receive incident light beams, wherein the photoreceptive surface is a surface of the solar cell system and parallel to the straight line. |
