Problems solved by technology
The concentrating photovoltaic photoelectric conversion receiver is mainly composed of a circuit substrate and a concentrating photovoltaic cell chip. The circuit substrate and the concentrating photovoltaic cell chip are fixed by solder paste, and the solder paste is applied to the circuit substrate by a roller and a steel mesh. At present, the traditional coating process is used for processing and manufacturing. In addition to conducting electricity, the solder paste in the concentrating photovoltaic photoelectric conversion receiver also takes into account the heat transfer function. Since the current concentrating photovoltaics mostly use hundreds of thousands of times Concentrating light, the temperature at the focal spot is much higher than 100 degrees Celsius. The traditional coating method will form a lot of gaps between the solder paste and the concentrated photovoltaic cell chip, which is not conducive to the rapid transmission of heat to the radiator on the back of the circuit substrate. Easy to burn concentrating photovoltaic cell chips

The invention relates to a coating processing method for a concentrating photovoltaic solder paste, and belongs to the technical field of solar power generation. The method comprises the following steps: firstly, putting the cleaned circuit substrate on a platform which is to be coated with the solder paste, and putting a steel net on the circuit substrate to ensure that steel net meshes are completely overlapped with a concentrating photovoltaic cell chip region of the circuit substrate; secondly, putting the solder paste into the steel net meshes, evenly grinding the solder paste into the steel net meshes by a roller, and flatly pressing uneven gaps in the solder paste in the steel net meshes by a scraper; and finally putting a concentrating photovoltaic cell chip on the steel net meshes. According to the processing method, the solder paste can be effectively coated flatly; the gaps in the solder paste are reduced; and quick transmission of heat to a radiator from the concentrating photovoltaic cell chip through the circuit substrate is facilitated, so that the concentrating photovoltaic cell chip is prevented from being damaged by the heat converged on focal spots.
