To provide a movable body and an optical wireless power supply system having a light reception module that can perform highly efficient power generation.SOLUTION: A movable body according to one embodiment of the present disclosure comprises: a light reception unit which includes a photoelectric conversion part that receives laser light to convert it into the power and a diffusion member that is arranged on a light reception surface side of the photoelectric conversion part and transmits the laser light while diffusing the laser light; a power storage unit which stores the power converted by the photoelectric conversion part; and a drive unit which drives a power device using the power stored in the power storage unit. The diffusion member diffuses the laser light such that the laser light having a smaller beam diameter than the length of one side of the light reception surface of the photoelectric conversion part is irradiated on the entire light reception surface of the photoelectric conversion part.SELECTED DRAWING: Figure 3
【課題】本発明は、高効率な発電を可能にする受光モジュールを有する移動体及び光無線給電システムを実現することを目的とする。【解決手段】本開示の一実施形態に係る移動体は、レーザー光を受光し電力に変換する光電変換部、及び該光電変換部の受光面側に配置され、レーザー光を拡散させつつ透過させる拡散部材を含む受光部と、光電変換部が変換した電力を蓄電する蓄電部と、蓄電部が蓄電した電力を用いて動力装置を駆動する駆動部と、を有し、拡散部材は、光電変換部の受光面の1辺の長さより小さいビーム径を有するレーザー光が光電変換部の受光面全体に照射されるように、レーザー光を拡散させることを特徴とする。【選択図】図3
