Related experiment and effect data:
the photovoltaic modules having the two-sided pattern in examples 1 to 5 and comparative examples 1 to 4 were subjected to a generated power test under the following conditions:
at 1000W/m 2 And the natural light with light intensity irradiates one surface of the ITO film of the light-transmitting photovoltaic panel, and the generated power is tested.
The test results are shown in the following table:
| generating power (W) | |
| Example 1 | 51.7 |
| Example 2 | 53.9 |
| Example 3 | 54.2 |
| Example 4 | 54.1 |
| Example 5 | 53.7 |
| Comparative example 1 | 45.0 |
| Comparative example 2 | 45.2 |
| Comparative example 3 | 46.5 |
The generated power of example 1 was higher than that of comparative example 1, which suggests that the provision of the one-way see-through film can effectively increase the generated power of the light-transmitting photovoltaic panel.
The generated power of example 1 was higher than that of comparative example 2, and the generated powers of comparative example 1 and comparative example 2 were substantially at the same level, which suggests that the white pigment layer did not substantially contribute to the improvement of the generated power of the light-transmitting photovoltaic panel, and the one-way see-through film was able to effectively increase the generated power of the light-transmitting photovoltaic panel as compared to the white pigment layer.
The generated power of example 2 was higher than that of example 1, which suggests that the provision of the luminescent layer effectively increases the generated power of the light-transmitting photovoltaic panel.
The power generated in comparative example 3 was improved compared to comparative example 1, which demonstrates that the addition of the luminescent layer can improve the power generated by the light-transmitting photovoltaic panel. However, the increase in the generated power of comparative example 2 is greater than that of example 1, which means that in the presence of the unidirectional see-through film, a portion of the ultraviolet light is reflected, and the noctilucent layer absorbs more ultraviolet light and releases more visible light, so that the generated power of the light-transmitting photovoltaic panel is increased.
