Photovoltaic cell unit and use thereof

A photovoltaic cell unit, comprising a cell sheet, a first conductive connection strip, and a second conductive connection strip, wherein the first conductive connection strip and the second conductive connection strip are respectively arranged on two sides of the cell sheet, and the first conductive connection strip is parallel to the second conductive connection strip;

• a front surface of the cell sheet is connected to a bottom surface of the first conductive connection strip through a plurality of first metal wires parallel to each other;
• each of the plurality of first metal wires is fixedly connected to the bottom surface of the first conductive connection strip through a first electrical connection material;
• each of the plurality of first metal wires is further fixedly connected to the front surface of the cell sheet through a second electrical connection material;
• and an end of each of the plurality of first metal wires distant from the first conductive connection strip does not extend to an outer side of the cell sheet;
• a back surface of the cell sheet is connected to a top surface of the second conductive connection strip through a plurality of second metal wires parallel to each other;
• each of the plurality of second metal wires is fixedly connected to the top surface of the second conductive connection strip through a third electrical connection material;
• each of the plurality of second metal wires is further fixedly connected to the back surface of the cell sheet through a fourth electrical connection material;
• and an end of each of the plurality of second metal wires distant from the second conductive connection strip does not extend to the outer side of the cell sheet.
