Background
The photovoltaic module is an important component of a photovoltaic power station, the more the photovoltaic module fully utilizes light, the higher the generated energy is, and the method for improving the generated energy of the photovoltaic module is to improve the utilization rate of the light. The light enters the surface of the cell piece from the light sparse medium in the process that the light enters the light dense medium from the light sparse medium, the transmittance and the reflectivity of the light change along with the change of an incident angle, and when the incident angle is 0 (vertical incidence), the transmittance of the light is the maximum, and the reflectivity is the lowest; the loss caused by the phenomenon that the transmittance of light is gradually reduced and the reflectance is gradually increased as the incident angle is gradually increased is called as the incident angle loss, i.e., IAM loss.
In the outdoor power generation process of the photovoltaic module, along with the change of the solar altitude angle and the solar azimuth angle, the incident angle of light is always changed, and the generated energy of different corresponding photovoltaic modules is different due to the fact that IAMs (alternating incidence angles) corresponding to different glasses are different. The IAM of the conventional glass descends more smoothly when the incident angle is smaller, and descends almost linearly when the incident angle is larger; when the photovoltaic module is installed according to the optimal inclination angle, the larger incidence angle generally occurs when the radiation quantity is lower in the morning and evening, so that the change of the incidence angle does not cause too much influence on the radiation absorption quantity of the photovoltaic module all the year round; however, when the module is used as a curtain wall or a sound insulation wall and the like and needs to be vertically installed, a large incident angle occurs at noon with large radiant quantity, and the radiant quantity received by the photovoltaic module is reduced at the moment, so that the power generation quantity of the photovoltaic module is influenced.
