The invention discloses a P-type double-size solar cell module. The P-type double-size solar cell module is characterized in that P-type silicon is used as a substrate for fabricating a double-size solar cell, an N-type doping layer is finally formed in a front surface, N-type doping layers are formed in a back surface at intervals, a negative electrode is arranged on a front surface of a batterypiece, a positive electrode and a negative electrode are arranged on a back surface of the battery piece, the electrodes on the front surface and the back surface of each battery piece are connected with the same electrodes of the same battery piece, equivalently, each battery piece is only provided with the negative electrode and the positive electrode, and connection positions of the positive electrode, the negative electrode and the other battery pieces are respectively arranged at different two sides of the battery piece. The P-type double-size solar cell module provided by the invention has lower production cost and simpler production process, and a circuit connection mode easier to weld is achieved.
