The Photovoltaic (PV) Modular System welds aluminum strips to metallized glass on PV modules, creating an array with sufficient voltage and current to provide a practical source of electrical power. This ultrasonic welding system does not distort metals with heat or other consumables and avoids cracking of glass panels in the photovolatic cells.
In the PGRW process, both the welding pressure and thermal input are minimized, coupled with a concise welding duration to preserve cell integrity. However, given that both the interconnect foil and the surface electrode of the solar cells are characterized by ultra-thin structures, the rates of element diffusion are considerably elevated in ...
1 INTRODUCTION. The fabrication of silicon wafers and cells trends towards larger formats that reach to around 210-mm edge length. 1 Large cells, however, result in higher currents, which cause the series resistance contribution of the modules metallization to increase in effect. One way to counteract this loss is the reduction of the resistance by enlarging the effective cross …

The dimensions of PV ribbon, such as width, thickness and length, directly affect the welding effect and the performance of PV modules. Too thick or too thin welding ribbons will affect the welding effect and lead to a decrease in power generation efficiency. Therefore, the size of the welding ribbon needs to match the design of the cell exactly.
