Half-cell assembly

A half-cell assembly, comprising:

• multiple cell string sets connected in series sequentially, each cell string set comprising multiple cell strings connected in parallel, and each cell string comprising multiple half-cells connected in series sequentially;
• the multiple cell string sets being arranged along a first preset direction;
• in each cell string set, the multiple cell strings being arranged along the first preset direction;
• in each cell string, the multiple half-cells being arranged along a second preset direction;
• one of the first preset direction and the second preset direction being a long side direction of the half-cell, and the other is a short side direction of the half-cell;
• and
• an integrated junction box, wherein the integrated junction box and the multiple cell string sets are arranged along the second preset direction, and the multiple cell string sets are connected in parallel with diodes of the integrated junction box, respectively,
• wherein the integrated junction box further comprises a power supply module, a sampling module, a control module, a driving module, a control switch, and a switching diode;
• wherein the diode, the power supply module and the sampling module are connected in parallel, and the diode, the power supply module and the sampling module are connected with the control switch and the sampling module in series, respectively;
• an input end of the control module is electrically connected to the sampling module, an output end of the control module is electrically connected to the driving module, and the driving module is electrically connected to the control switch, so that the control module is capable of controlling the driving module to turn on and turn off the control switch according to signals from the sampling module.
