Abstract:
1. A solar cell system comprises: a plurality of P-N junction cells comprising M number of P-N junction cells, M being equal to or greater than 2, the plurality of P-N junction cells being arranged from a first P-N junction cell to an Mth P-N junction cell along a straight line and being electrically connected to each other in series, wherein 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 between each adjacent two of the plurality of P-N junction cells, a number of the inner electrode being M−1, at least one of the inner electrodes comprising an array of carbon nanotubes comprising a plurality of carbon nanotubes; wherein each of the plurality of carbon nanotubes comprises a first open end and a second open end, the first open end is in direct contact with and is electrically connected to one of the plurality of P-N junction cells, and the second open end is in direct contact with and is electrically connected 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; and the plurality of carbon nanotubes are substantially parallel to each other and a lengthwise direction of each of the plurality of carbon nanotubes is perpendicular with the first silicon layer and the second silicon layer; a first collecting electrode on an outside surface of the first P-N junction cell; a second collecting electrode on an outside surface of the Mth P-N junction cell; a reflector; a photoreceptive surface configured to directly receive incident light beams, the photoreceptive surface being a surface of the solar cell system and parallel to the straight line; and an emitting surface opposite to the photoreceptive surface, the emitting surface being another surface of the solar cell system, and the reflector being on the emitting surface.
