One can display images and harvest energy by utilizing ambient light with a stack of an optical shutter array, a luminescent layer and a solar cell. In our experiment, a luminescent layer and a corresponding color filter were attached to a polycrystalline Si solar cell with 13% power conversion efficiency. For each configuration using BBOT, Coumarin 6 and Lumogen F Red 305, the power conversion efficiency was measured to be 6.7%, 8.0% and 8.9%, respectively. The luminance of these configurations was proportional to the illuminance in all cases. Its color gamut was comparable to the National Television System Committee standard.
