Abstract
A free-space power receiver includes layouts of photovoltaic cells selected to optimize power extraction even when a power beam moves or changes profile on the receiver. The receiver may also include a circuit board, which may include suitable wiring for connecting the photovoltaic cells to one another and to a load for extraction of power. The receiver may include capacitors wired in parallel with the photovoltaic cells.
Claims15
A power receiver, comprising:
- a plurality of photovoltaic (PV) cells disposed on a support surface to form a PV array, the PV cells divided into a plurality of voltage groups;
- and
- electrical wiring for interconnecting the PV cells, the wiring configured to:
- connect each PV cell within a voltage group in parallel;
- and
- connect each voltage group to at least one other voltage group in series;
- and
- a capacitor connected in parallel with at least one PV cell of the plurality of PV cells,
- wherein:
- the PV cells of each voltage group are arranged in a repeating pattern along a first axis of the PV array;
- and
- the repeating pattern is staggered along a second axis of the PV array by an offset value, the offset value selected so that PV cells in the same voltage group are not adjacent to one another.
