PV cells, or solar cells, generate electricity by absorbing sunlight and using the light energy to create an electrical current. The process of how PV cells work can be broken down into three basic steps: first, a PV cell absorbs light and knocks electrons loose. Then, an electric current is created by the loose-flowing electrons.

QE of a solar cell can be unity or we can say that a solar cell behaves as an ideal one when all the charge carriers produced by all the photons (of particular energy or wavelength) are collected in a solar cell [9, 15]. It is important to note that if the energy of a photons is less than the bandgap of the material, the quantum efficiency will always be zero.

The Working Principle of PV Cells A PV cell is the essential unit of a solar energy generation system in which sunlight is promptly converted to electrical energy.
Solar PV technology is one of the optimum ways to utilize solar power to generate electricity by converting the sunlight to direct current in solar cells or PV cells [2, 3]. PV energy conversion utilizes devices based on electronic semiconductors, particularly but not exclusively, crystalline silicon (c-Si) or thin-film semiconductor materials.
A suitable combination is a laser diode emitting around 750–980 nm and a photovoltaic cell based on silicon or GaAs, or possibly InGaAs. While GaAs-based cells are the most efficient, they are also much more expensive.
Solar panels are multiple solar cells connected in series and parallel to produce a certain power output. One PV cell is unfeasible for most applications as it can only produce about 0.5 V. For example, six cells are connected in series, the cell is assumed to have the same current as a single cell and ideal 3 V (6 × 0.5 V).
While most photovoltaic cells are used for solar power generation, some are used for Power over Fiber (PoF), i.e. to deliver power in the form of light through an optical fiber (typically a multimode fiber). The requirements for the cell are very different from those for solar power generation:
Photovoltaic cells generate a voltage between their front and backsides. Both sides must be electrically contacted. At least for the front side (and for bifacial cells, the backside as well), this must be done in such a way that the light input is reduced as little as possible.
