1. A method for manufacturing at least one solar cell, comprising:
obtaining a quasi-square silicon wafer having at least one arc, a length of each of the at least one arc being not less than 15 mm;
forming the at least one solar cell by processing the quasi-square silicon wafer; and
scribing the at least one solar cell to obtain a square-shaped sub-solar cell and at least one strip-shaped sub-solar cell, a number of the at least one strip-shaped sub-solar cell being equal to a number of the at least one arc of the quasi-square,
wherein obtaining a quasi-square silicon wafer having at least one arc includes:
providing a monocrystalline silicon rod;
squaring the monocrystalline silicon rod to form a quasi-square silicon rod with a quasi-square cross-section having the at least one arc, the length of each of the at least one arc being not less than 15 mm; and
slicing the quasi-square silicon rod to form the at least one quasi-square silicon wafer having the at least one arc.
