Embodiment Construction

[0035] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .

[0036] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only.

Abstract

The invention discloses a manufacturing method of a photovoltaic module and a photovoltaic module, comprising the following steps: slicing, cutting a silicon round rod into circular slices, and slicing into hexagonal battery slices along an inscribed hexagonal shape of the circular slices; Printing, printing front main grid line, thin grid line and back main grid line of hexagonal battery sheet; Cutting, cutting the hexagonal battery sheet into a quarter slice in transverse and longitudinal halving; A quarter of the slices are arranged according to complementary shapes and arranged in series to form a battery string in turn; Package, which encapsulates several battery strings. The invention forms the shape of the battery sheet into a hexagonal shape, and reduces the waste of silicon material in cutting corners of circular silicon rods. The hexagonal battery slices are cut into a quarter of slices, and the quarter slices are arranged according to the corresponding complementary shapes to form a rectangular shape, thereby facilitating automatic connection of the battery slices and increasing the area utilization ratio of the components; A main grid line on that cell chip is design sothat the cell chip is connected in series to increase the power of the photovoltaic module.

Description

technical field [0001] The invention relates to the technical field of photovoltaic components, in particular to a method for manufacturing a photovoltaic component and the photovoltaic component. Background technique [0002] Photovoltaic power generation process is simple, no consumption, zero emissions, and no environmental pollution. Against the background of increasingly serious energy crisis and environmental pollution, photovoltaic power generation, as a green and environmentally friendly renewable energy, is increasingly favored by governments of all countries. For a long time, two important issues restricting the development of photovoltaic industry are photoelectric conversion efficiency and production cost. Crystalline silicon cells are usually divided into monocrystalline cells and polycrystalline cells. In the production process of monocrystalline silicon cells, it is first necessary to make round silicon rods. The rounded corners are cut off to form a quadril...
