Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a construction process and equipment for improving the power generation efficiency of photovoltaic modules. Background Art
[0002] As the photovoltaic module industry has made the leap from small size to large format, the power of a single module has gradually increased with the increase in cell size and the improvement in single-chip efficiency. However, the power generation efficiency and photoelectric conversion efficiency of the module are limited by the differences in light transmittance of glass / backplane, EVA / POE material, and cell technology type PERC / Topcon / HJT, resulting in inconsistent power generation efficiency and conversion efficiency under different BOMs. Currently in the module industry, after the cells are loaded, soldered, and stacked, the glass or backplane is placed directly and flatly on the module cell string and EVA during the second process of glassing. At present, the mainstream in the industry is 182-210mm cells, and the cells are transformed from PERC to Topcon. With the same cell size and cell type under the same size specification, the consumables under the BOM list under the same double-glass version, and an additional process after the second process of glass application; in the second process of glass application in the gap film assembly process, the glass loader grabs the glass or backplane and puts it on the assembly line, and transports the glass or backplane to the glass assembly station through the assembly line. The glass or backplane is directly laid flat on the semi-finished assembly. At this time, the gap between the solar cell and the glass backplane is large, which not only increases the light loss in this interval, resulting in a decrease in light utilization; and often due to this large gap, partial stress concentration occurs, increasing the risk of fragmentation during the lamination process.

The photovoltaic module 1 grabs the low-position glass from the second glass feeding mechanical arm of the module and transports it to the high-position assembly line platform, so that the photovoltaic module 1 completes a 90-degree turn and is transmitted to the interval film pasting area by the assembly plane. The photovoltaic module 1 enters the interval film pasting area from the module inflow direction 2, and the position of the photovoltaic module 1 is adjusted by the correction mechanism 3. The photovoltaic module 1 is horizontally transported by the transmission member to the upper hub-interval reflective film feeding 6.
[0022] A construction process and equipment for improving the power generation efficiency of photovoltaic modules, including an upper hub-spacer reflective film feeding 6, after the photovoltaic module 1 is assembled, it turns 90 degrees from the module inflow direction 2 to enter the interval film pasting area, and then the direction is adjusted by the correction mechanism 3, so that the photovoltaic module 1 enters the upper hub-spacer reflective film feeding 6 along with the transmission mechanism 4 for film pasting, and after the photovoltaic module 1 is pasted, it is cut by the reflective film pasting-cutting mechanism 5 and flows out from the module outflow direction 7
[0023] The solar module gap reflective film affixed to the photovoltaic module 1 is to protect the service life of this structure. The solar module gap reflective film is made of high-transmittance COC and COP materials, and the high transmittance is used to increase the light utilization rate. These two materials have excellent transparency and purity, as well as good toughness and low water absorption. The transmittance reaches more than 90%, reducing the scattering and refraction of light.
[0024] The photovoltaic module 1 includes a cell and a glass back plate. There is a large gap between the cell and the glass back plate after installation. The solar module gap reflective film is attached to the cell and the glass back plate by the upper hub-spacer reflective film feeder 6. The high light transmittance is used to reduce reflection and loss, improve utilization, and ultimately achieve the effect of improving the photoelectric conversion efficiency and power generation efficiency of the photovoltaic module 1, and improve the power generation efficiency of the photovoltaic module 1 by more than 5% to 10%.

The transmission mechanism 4 transports the photovoltaic module 1 to run in the interval film-pasting area and complete the film-pasting. The upper hub-interval reflective film feeding 6 is used to position the photovoltaic module 1 so that the photovoltaic module 1 is film-pasted in the correct position. After the photovoltaic module 1 is filmed, the reflective film-cutting mechanism 5 cuts off the reflective film in the gap of the solar module. After all steps are completed, the long side of the photovoltaic module 1 flows out from the module outflow direction 7 of the interval film-pasting area.
