Patent Number: 8,878,123

Title: Lens sheet and photoelectric conversion module

Abstract: A lens sheet is provided which is configured to create, below the lens sheet, a region not irradiated with light when light is incident on the lens sheet from above. A photoelectric conversion element is efficiently irradiated with light incident on the lens sheet. In addition, a high-efficiency photoelectric conversion module is provided. The lens sheet includes a light-transmitting substrate having lens arrays on both sides, and the lens arrays each have lens regions and non-lens regions placed alternately (in stripes), in which an end portion of each lens region on the front side overlaps with an end portion of each lens region on the back side.
