Claim Text:
1. A solar cell system, comprising: a plurality of solar cells arranged in two-dimensional array comprising a plurality of solar cells columns and a plurality of solar cells rows; wherein solar cells in the same one of the plurality of solar cells columns are stacked, in direct contact with each other and electrically connected to each other in series so that each of the plurality of solar cells columns has a curved surface, and solar cells in the same one of the plurality of solar cells rows are in direct contact with and electrically connected to each other in parallel; and the solar cell system has a common curved surface configured to receive incident light beams and a common planar surface opposite to the common curved surface; each of the plurality of solar cells comprising: an integrated structure comprising a first electrode layer, a P-type silicon layer, an N-type silicon layer, and a second electrode layer arranged in the above sequence; and a P-N junction at an interface between the P-type silicon layer and the N-type silicon layer; wherein adjacent P-type silicon layers in the same one of the plurality of solar cells rows are in direct and parallel contact with each other; and adjacent N-type silicon layers in the same one of the plurality of solar cells rows are in direct and parallel contact with each other.
