The present invention relates to a road sign using a dye-sensitive solar cell, which improves visibility of a road sign by using a power generation property in a lower illumination and a color expression property of the dye-sensitive solar cell. The road sign using a dye-sensitive solar cell also simplifies an equipment structure and improves visibility by enabling power generation of photoelectric transformation in an environment in which sunlight is weak or does not exist. According to the present invention, the road sign using the dye-sensitive solar cell includes: a support plate providing a mounting place for an LED module and a dye-sensitive solar cell module; the dye-sensitive solar cell module installed on the support plate, wherein the dye-sensitive solar cell module produces power by photoelectric transformation of radiated light and expresses a predetermined color on the road sign; and the LED module installed on the dye-sensitive solar cell module and receiving the power produced by the dye-sensitive solar cell module to emit the light. A part of a mark among multiple marks forming the road sign is formed by the dye-sensitive solar cell module, and the other part of the mark is formed by the LED module. |
