1. A remote power system, comprising:
a remote power transmitter configured to output a high-flux power beam from a laser; and
a remote power receiver configured to receive the high-flux power beam, the receiver including:
at least two photo-voltaic (PV) cells configured to convert at least a portion of light energy of the high-flux power beam to electrical energy;
a non-PV structure adjacent to the at least two PV cells; and
a light-steering structure configured to steer flux away from the non-PV structure and toward the at least two PV cells, wherein the light-steering structure has a concentration ratio in the range of about 1.5 to about 50.
