Abstract
A system may include a solar cell and a modulator connected to an output of the solar cell. The system may receive a signal. When the signal being in a first state corresponding to modulation, the modulator may modulate voltage output of the solar cell and cause the solar cell to perform optical transmission. When the signal is in a second state corresponding to energy harvesting, the modulator to cease modulation of the output of the solar cell.
Claims7
A system comprising:
- a solar cell;
- a modulator connected to an output of the solar cell;
- and
- an input configured to receive a signal, wherein the signal being in a first state causes the modulator to modulate voltage output of the solar cell and cause the solar cell to perform optical transmission, the signal being in a second state causes the modulator to cease modulation of the output of the solar cell, and
- wherein the modulator comprises a transistor and an op-amp in a feedback loop configuration.
