Abstract: A transmittance enhancement film is provided, which includes a substrate and a coating layer on the substrate. The coating layer includes a plurality of organic particles and a binder. The organic particles have a refractive index of less than 1.5, and the refractive index ratio of the organic particles to the binder is in the range from 0.95 to 1.05. The transmittance enhancement film of the present invention is suitable for being used in a solar cell module, and is capable of enhancing the transmittance of light, thereby improving the power generation efficiency of the solar cell module.

Abstract: The present invention is directed to a film used for a solar cell module and the module thereof, in which the film includes a substrate and at least one light-regulating layer, and the light-regulating layer includes a fluoro resin and a plurality of light diffusing additives. By applying the film of the subject invention in a solar cell module, the film can make the solar cell have good light utilization.
