[0051] test:
[0052] The effects of the photovoltaic modules obtained above are compared, and the results are as follows:
[0053]
[0054]
[0055] The utility model provides color layers (first and second color layers) of different colors on the trapezoidal pattern structure of the glass body, so that the component can present various color effects at different angles, thereby increasing its aesthetics and visual effects.
