Connection of Cells in Photovoltaic Modules. As shown in Fig. 5, the solar cells in the modules with different surface structures of welding strips have no cracks, and there is no open welding, false welding and desoldering, which indicates that it can be used for the subsequent research.
The quality of welding strip will directly affect the current collection efficiency of photovoltaic module, so it has a great impact on the power of photovoltaic module. The so-called photovoltaic welding strip is to coat binary or ternary low-melting alloy on the surface of copper strip with given specification.
The current is determined by the minimum through current. Macroscopically, the voltage of photovoltaic module is determined by the number of cells in series, and the current is determined by the area of single cell. Fig. 4. Connection of Cells in Photovoltaic Modules.
The welding strip is an important part of photovoltaic module. The current of the cell is collected by welding on the main grid of the cell. Therefore, this paper mainly studies the influence of different surface structure of heterogeneous welding strip on PV assembly power improvement. The main findings are as follows:
According to customer requirements, nine pieces or ten pieces or twelve pieces are connected together in each string. In this way, the series resistance of the whole photovoltaic module is the superposition of the series resistances of cells, plus the sum of connecting wire and contact resistance.
The packaging process of photovoltaic modules is described as follows: The core of cell is the internal PN junction. According to the current diffusion technology, the voltage at both ends of the battery is about 0.50 V, and the working current is about 8 A.
