technical field

With the wider application of solar photovoltaic modules, more and more customers put forward higher requirements for the photoelectric conversion efficiency and appearance of photovoltaic modules.

In order to improve the conversion efficiency and aesthetics of photovoltaic modules, it is necessary to process the bus bars on the photovoltaic modules. The traditional method is generally realized by painting or sticking films on the bus bars. For example, the cells, frames and backplanes of all-black photovoltaic modules are made of black materials. In order to achieve the all-black effect of photovoltaic modules, the bus bars also need to use black bus bars. The common method of making black bus bars is to apply a layer of black paint on the surface of the silver bus bars or stick a black film on the silver bus bars. Due to the high preparation cost of the former and the non-conductive black paint, it is necessary to scrape the lead wires when making the lead wires. It is very troublesome to remove the black paint, so customers are more inclined to stick the film on the bus bar.
