The application relates to a parallel light total reflection light splitting prism suitable for solar frequency splitting and a use method thereof. The light splitting prism is made of optical glass and comprises an incident surface, an emitting surface, a first working surface and a second working surface. The incident surface is opposite to the emitting surface, the first working surface is opposite and parallel to the second working surface, and the included angle between the incident surface and the second working surface is equal to a critical angle corresponding to a light splitting wavelength. After parallel light beams are perpendicularly incident on the incident surface, the light beams are sequentially subjected to light splitting for several times through the second working surface, the first working surface, the second working surface, the first working surface and so on, light beams with wavelengths greater than the light splitting wavelength are emitted outside the first working surface and the second working surface, and light beams with wavelengths less than or equal to the light splitting wavelength are perpendicularly emitted by the emitting surface. The parallel light total reflection light splitting prism does not rely on film coating to realize light splitting, but only utilizes light to realize total reflection when the light is incident on a light-lean medium from a light-dense medium at a critical angle or smaller than the critical angle, and realizes refraction when the light is incident on the light-lean medium at a critical angle or greater than the critical angle, so that light splitting is realized.

This invention provides a solar beam-splitting film and a photovoltaic module, specifically relating to the field of solar cell technology. The solar beam-splitting film comprises, from top to bottom, an upper substrate layer, a prism structure layer, and a lower substrate layer stacked together. The prism structure layer includes periodically arranged prism units, each with a triangular cross-section, and adjacent prism units forming a cavity structure. The refractive index of the prism units is 1.45–1.8. The solar beam-splitting film provided by this invention ensures that light meets the total internal reflection condition at the prism interface, thereby efficiently reflecting light that would otherwise illuminate inefficient areas such as gaps or edges of the solar panels to the surface of the photovoltaic cells. Furthermore, the cavity structure further optimizes the light path control capability through the difference in refractive index between the air medium and the prism material. This solution completely avoids conductivity limitations, allowing safe application in high-voltage conductive areas, while also preventing light energy waste caused by photovoltaic wiring obstruction, thus improving the overall light energy recovery efficiency of the photovoltaic module.
