Abstract

A photovoltaic power source includes a receptacle to receive a photofuel including a liquid, and one or more photovoltaic cells positioned within the receptacle to receive light emitted from the photofuel when the photofuel is in the receptacle. The photovoltaic power source also includes power circuitry coupled to the one or more photovoltaic cells to receive a photocurrent generated by the one or more photovoltaic cells when the one or more photovoltaic cells receive the light emitted from the photofuel. In response to the photocurrent, the power circuitry is coupled to output electricity.

First claim

What is claimed is:

1. A photovoltaic power system, comprising:
a receptacle shaped to receive a photofuel including a liquid;
a channel disposed within the receptacle for guiding or confining the photofuel within the receptacle;
a catalyst lining at least a portion of the channel, wherein the catalyst encourages photoemission of light by the photofuel when in physical contact with the photofuel;
one or more photovoltaic cells positioned within the receptacle to receive the light emitted from the photofuel when the photofuel is in the receptacle; and
power circuitry coupled to the one or more photovoltaic cells to receive a photocurrent generated by the one or more photovoltaic cells when the one or more photovoltaic cells receive the light emitted from the photofuel, wherein in response to the photocurrent, the power circuitry is coupled to output electricity.

2. The photovoltaic power system of claim 1 , wherein an absorption spectrum of the one or more photovoltaic cells positioned in the receptacle overlaps an emission spectrum of the photofuel, at least in part, and wherein the catalysts and the photovoltaic cells are disposed on opposing sides of the channel facing each other.

3. The photovoltaic power system of claim 1 , wherein the power circuitry includes a power storage unit coupled to receive the photocurrent from the one or more photovoltaic cells, and a power converter coupled to the power storage unit to output a DC waveform.

4. The photovoltaic power system of claim 1 , further comprising:
one or more input ports to the receptacle, wherein the receptacle receives the photofuel through the one or more input ports; and
one or more output ports from the receptacle, wherein the receptacle outputs the photofuel through the one or more output ports.

5. The photovoltaic power system of claim 4 , wherein the one or more input ports continuously receives the photofuel and the one or more output ports continuously outputs the photofuel from the receptacle, while the photovoltaic power system is operating.

6. The photovoltaic power system of claim 1 , wherein the receptacle comprises a first receptacle, the photovoltaic power system further comprising:
a second receptacle to receive the photofuel; and
trigger mechanisms coupled to the first and second receptacles and configured to spark out-of-phase photoemissions of the light between the first and second receptacles.

7. The photovoltaic power system of claim 6 , wherein the trigger mechanisms for sparking the out-of-phase photoemissions of the light between the first and second receptacles each comprise one of a valve for controlling pH of the photofuel, a laser, or a heater.

8. The photovoltaic power system of claim 1 , wherein the channel comprises a gradually widening portion that widens in a direction of a flow of the photofuel through the channel to gradually slow a progression of the photofuel through the gradually widening portion as the channel widens, and wherein the solar cells are lined along the gradually widening portion.

9. The photovoltaic power system of claim 1 , wherein the channel is divided into a first sub channel and a second sub channel, wherein a clear divider is disposed between the first sub channel and the second sub channel, and wherein the photofuel flows in a first direction in the first sub channel and the photofuel flows in a second direction in the second sub channel, wherein the first direction is opposite the second direction.

10. The photovoltaic power system of claim 1 , wherein the photofuel emits light through at least one of an isomer transformation, an electrochemiluminescent reaction, a chemiluminescent reaction, or delayed fluorescence.

11. The photovoltaic power system of claim 1 , further comprising an electric motor coupled to the power circuitry to receive the electricity and convert the electricity into mechanical energy.

12. The photovoltaic power system of claim 11 , wherein the receptacle, the power circuitry, and the electric motor are disposed within, and the electric motor is mechanically coupled to provide the mechanical energy to move, one of an aircraft body, a boat hull, or a vehicle chassis.

13. The photovoltaic system of claim 1 , further comprising one or more charging pods configured to receive energy to charge the photofuel when the photofuel is within the charging pods, wherein the energy provided to charge the photofuel allows the photofuel to emit the light.

14. The photovoltaic system of claim 13 , further comprising one or more storage tanks coupled to the charging pods to receive the photofuel after the photofuel has been charged, and wherein the one or more storage tanks is configured to output the photofuel to the receptacle.

15. A method for generating power, comprising:
receiving a photofuel, including a liquid, with a receptacle including one or more photovoltaic cells disposed within the receptacle;
emitting light from the photofuel when the photofuel is in the receptacle;
flowing the photofuel though a channel positioned in the receptacle, wherein the photovoltaic cells are positioned in the channel to receive the light from the photofuel, wherein at least a portion of the channel is lined with a catalyst that encourages photoemission of the light by the photofuel when in physical contact with the photofuel;
absorbing the light with the one or more photovoltaic cells disposed within the receptacle;
generating a photocurrent with the one or more photovoltaic cells, in response to the one or more photovoltaic cells absorbing the light; and
outputting electricity with a power system coupled to the one or more photovoltaic cells to receive the photocurrent.

16. The method of claim 15 , further comprising powering an electric motor coupled to the power system, wherein in response to receiving the electricity the electric motor outputs mechanical energy.

17. The method of claim 16 , further comprising moving one of a boat hull, a vehicle chassis, or an aircraft body with the mechanical energy output from the electric motor.

18. The method of claim 15 , further comprising charging the photofuel with second light before flowing the photofuel into the receptacle.

19. The method of claim 15 , wherein the electricity includes a DC waveform generated by a power storage unit and power converter included in the power system.

20. The method of claim 15 , wherein emitting the light from the photofuel includes emitting the light through at least one of an isomer transformation, a chemiluminescent reaction, an electrochemiluminescent reaction, or delayed fluorescence.

21. The method of claim 15 , wherein absorbing the light with the one or more photovoltaic cells includes using the one or more photovoltaic cells having an absorption spectrum that overlaps an emission spectrum of the photofuel, at least in part.

22. The method of claim 15 , wherein flowing the photofuel into the receptacle includes immersing the one or more photovoltaic cells in the photofuel, at least in part.

23. A photovoltaic power system, comprising:
a receptacle shaped to receive a photofuel including a liquid, wherein the receptacle includes a smaller inner channel and a larger outer channel that encircles the smaller inner channel and wherein the photofuel is confined to the smaller inner channel but not the larger outer channel;
one or more photovoltaic cells positioned within larger outer channel of the receptacle to receive light emitted from the photofuel th
