Sunlight passes through the glass and the packaging adhesive film, reaches the battery piece to perform photoelectric conversion, and is converted into electric energy by the light energy, the absorption and the loss of the sunlight in the photovoltaic module are greatly related to the packaging adhesive film, the refractive index of the packaging adhesive film is generally between 1.46 and 1.49, certain difference exists between the refractive index of the packaging adhesive film and the refractive index of the glass, and the packaging adhesive film cannot efficiently utilize incident light due to higher reflection at the interface of the glass and the battery piece, so that the photovoltaic module has low utilization rate of the sunlight and low power output of module power generation.
Therefore, in order to avoid the limitation of the packaging adhesive film on further improving the photoelectric conversion efficiency of the photovoltaic module, the scattering property of the packaging adhesive film needs to be improved to realize the optical matching of the glass/packaging adhesive film/the battery piece and reduce the photovoltaic packaging loss. The light utilization rate of the battery piece is related to the conversion efficiency of the battery piece and the optical characteristics of glass and a glue film at the front end of the battery piece, and the light utilization rate needs to be improved by adjusting the scattering characteristics of the glue film; however, the higher the light transmittance of the adhesive film, the higher the light utilization rate of the battery piece after the packaging is not necessarily; the higher the haze of the film, the less the light trapping effect of the film is necessarily the best.

And (3) testing:
the photovoltaic modules of examples 1 to 3 and comparative examples 1 to 2 were subjected to reflection intensity, light transmittance, and haze test (haze refers to the total haze of the front glass 1 and the photovoltaic packaging film layer 2), and the test results are shown in the following table. Wherein: the reflection intensity test process is as follows: the illumination intensity is 1.0W/m from the front glass 1 2 And then the intensity of the reflected light is tested at the front glass 1.
| Diffusing agent type and volume concentration | Reflection intensity | Transmittance of light | Haze degree | |
| Example 1 | MgO、0.05％ | 0.135cd/m 2 | 88％ | 36％ |
| Example 2 | ZnSiO 3 、0.09％ | 0.136cd/m 2 | 80％ | 50％ |
| Example 3 | Al 2 O 3 、0.12％ | 0.141cd/m 2 | 75％ | 55％ |
| Comparative example 1 | None, 0 | 0.144cd/m 2 | 91％ | ＜1 |
