6 FAQs about [Solar cell mode]
Why do solar cells use PC mode?
The PV effect forms the basis for the solar cells. The PC mode is used in photodetection applications and has the advantages of having a lower capacitance that improves the response time and the presence of an external electric field facilitates the separation of electron–hole pairs improving the responsivity
How does a solar cell work?
The light enters the emitter first. The emitter is usually thin to keep the depletion region near where the light is strongly absorbed and the base is usually made thick enough to absorb most of the light. The basic steps in the operation of a solar cell are: the dissipation of power in the load and in parasitic resistances.
