Embodiment 1

[0043] A solar cell uses TPT material to make a substrate, and uses EVA material to make a surface sealing layer on the surface of the substrate. The sealing layer includes an array composed of arcuate solar cell modules, and the surface of the sealing layer is a covering layer made of glass.

[0044] Such as Figure 8 Shown is an array of arcuate solar cell modules in this embodiment. The array is composed of 18 rows of bow-shaped solar cell modules, each row includes 4 bow-shaped solar cell modules, and the arrangement of the bow-shaped solar cell modules in the first row is the same. The bow-shaped solar cell module adopts a monocrystalline silicon substrate, the arc radius of the arc surface is 100 mm, and the corresponding central angle is 74 degrees.

[0045] The upper surface of each bow-shaped solar cell module is a negative electrode, and the lower surface is a positive electrode. There are two busbars on the upper and lower surfaces, and the busbars are located on ...

Embodiment 2

[0046] A solar cell uses TPT material to make a substrate, and uses EVA material to make a surface sealing layer on the surface of the substrate. The sealing layer includes an array composed of arcuate solar cell modules, and the surface of the sealing layer is a covering layer made of glass.

[0047] Such as Figure 9 Shown is an array of arcuate solar cell modules in this embodiment. The array consists of 18 columns of bow-shaped solar cell modules, each column including 4 bow-shaped solar cell modules. The solar battery modules in two adjacent rows are distributed axisymmetrically with the central line of the two rows as the axis of symmetry. The bow-shaped solar cell module adopts a monocrystalline silicon substrate, the arc radius of the arc surface is 100 mm, and the corresponding central angle is 74 degrees.

[0048] The upper surface of each bow-shaped solar cell module is a negative electrode, and the lower surface is a positive electrode. There are two busbars on ...

Abstract

The invention provides a solar energy battery which comprises a solar energy battery module array, and the solar energy battery is characterized in that the solar energy battery module array comprises at least two adjacent arc solar energy battery modules in the row direction; arc faces of the adjacent arc solar energy battery modules in the row direction form adjacent overlapping or tangent overlapping on taper angles; and the arc faces are mutually parallel. The solar energy battery has the advantages of enhancing output of the solar energy battery under the condition of without increasing the investment of underlay materials and providing a compact arrangement program of the arc solar energy battery module to make adjacent arcs be mutually crossed; and the distance between the arc solar energy battery module array and the modules formed by adopting the mode is shortened, and the arrangement is compact.

Description

technical field [0001] The invention relates to the field of solar cells, in particular to the arrangement of solar cell units and the solar cell. Background technique [0002] With the continuous development of the global economy, the damage to the environment is also becoming more and more serious. Environmental protection is one of the important issues facing all countries in the world. The use of clean energy instead of traditional energy can improve the living environment and improve environmental quality, which is an important environmental protection measure. Solar cells directly convert light energy into electrical energy, and no pollutants are produced during the energy conversion process. It is a new type of clean energy. In the invention patent CN1161844C, a solar cell module using a surface side covering material of a non-woven glass fiber component is disclosed. [0003] Such as figure 1 As shown, it is a schematic cross-sectional view of a solar cell struct...
