Electric power is the product of the voltage across a device and the current through that device. Engineers use the theoretical power to characterize a solar cell. The power provided by the sun per unit area, known as solar intensity, is approximately 1,000 Watts per meter squared.
The power of a solar cell is the product of the voltage across the solar cell times the current through the solar cell. Here’s how to calculate the power the solar cell delivers to the motor: The maximum theoretical power from our solar cell, Pmax, is the product of the Voc and Isc.
The sunlight is a group of photons having a finite amount of energy. For the generation of electricity by the cell, it must absorb the energy of the photon. The absorption depends on the energy of the photon and the band-gap energy of the solar semiconductor material and it is expressed in electron-volt (eV).
The maximum current that a solar cell can produce occurs when a wire is connected across the terminals. This is called the short-circuit current, or Isc. Like a wire, an ammeter has very low resistance, so will register a measurement similar to a short circuit. Note the Isc through the solar cell.

This is known as the power conversion efficiency (PCE) and is the ratio of incident light power to output electrical power.
Various factors govern the electricity generated by a solar cell such as; The intensity of the light: Higher sunlight falling on the cell, more is the electricity generated by the cell. Cell Area: By increasing the area of the cell, the generated current by the cell also increases.
