Embodiment Construction

[0019] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0020] Explanation of terms:

[0021] Black solar cell module: Refers to a solar cell module that is black when viewed from the top or side of the solar cell module.

[0022] see figure 1 As shown, according to the embodiment of the present invention, the black solar cell assembly includes a black backplane 10 and a plurality of battery sheets 20 arranged at intervals on the black backplane 10, and a facing battery piece is arranged between the battery pieces 20 and the black backplane 10. 20 reflective enhanced reflective structure 30 . In this embodiment, an enhanced reflective structure 30 that reflects light towards the battery sheet 20 is provided between the battery sheet 20 and the black back plate 10. When using the black solar cell module...

Abstract

The invention provides a black solar battery component. The black solar battery component comprises a black back panel and a plurality of cells arranged on the black back panel at intervals, wherein a reflection enhancing structure facing to reflection of the cells is arranged between the cells and the black back panel. When the black solar battery component is in use, after light irradiated on the cells is refracted to the reflection enhancing structure through the cells, the reflection enhancing structure with high reflectivity can reflect light to the cells to be absorbed, so that the package loss of the whole solar battery component is reduced and the power of the black solar battery component per unit area is improved.

Description

technical field [0001] The present invention relates to the field of solar cells, more specifically, to a black solar cell assembly. Background technique [0002] Conventional solar cell modules use black backsheets and black frames. This type of module is mainly used in scattered rooftop grid-connected systems. Because users have high requirements for the appearance of modules, manufacturers have developed black solar cell modules. Black The solar cell module solves the problem of large color difference between the battery inside the module and the back plate and the frame, so that the color consistency of the module is well resolved. However, there are still the following problems in black solar cell modules: [0003] Because the back sheet is black, the reflectivity of the solar cell module is reduced, and the packaging loss of the module is high. Compared with the conventional solar cell module, the packaging loss is about 3% higher, and the power of the same solar cell...
