Patent number: 10381497Abstract: An apparatus and method for optical-power-transfer (OPT). A light source converts electrical energy into light, and the light is transmitted from the active layer of the light source directly to the active layers of a series of photovoltaic (PV) devices without first passing through a conduction layer of the PV device. Thus, absorption in the conduction layer is avoided, and the efficiency of the OPT system is improved. The PV devices are configured to each generate equal current, and the PV devices are electrically connected in series. PV devices are arranged in series with light first propagating through PV devices closer to the light source, and farther PV devices having a longer propagation length, such that the light absorbed and current generated by each PV device is equal to the other PV devices. In one implementation, the PV devices are configured in a laser cavity with the light source.Type: GrantFiled: January 5, 2018Date of Patent: August 13, 2019Assignee: TOYOTA MOTOR ENGINEERING & MANUFACTURING NORTH AMERICA, INC.Inventor: Masanori Ishigaki
