The present invention relates to a power generating module and light guiding film thereof. The light guiding film includes a film base and at least one microstructure. The microstructure is disposed on a side surface of the film base. After the input light beams pass through the light guiding film, the total luminous flux of the output light beams with the output angles from 70 to 110 degrees is more than 40% of the total luminous flux of the output light beams with the output angles from 0 to 180 degrees. Therefore, most of the output light beams emit in the normal direction.
