A solar cell is basically a P-N junctions diode. Based on the photovoltaic cell working principle, solar cells are a form of photoelectric cell – such as currents, voltage, or resistance – differ when exposed to light.. Individual solars cells can be combined to form modules known as solar panels. Common single-junction silicon solar panels can produce maximum open-circuit voltages of ...
The working principle of solar panels is to use the photoelectric effect, also known as the photovoltaic effect. Photovoltaic effect refers to the phenomenon that an object generates electromotive force due to the absorption of photons. The photovoltaic effect occurs when sunlight or other light strikes the PN junction of a semiconductor.
In a solar cell, the asymmetry that is needed to extract electrons from the CB and holes from the VB is achieved by creating a pn junction. The term pn junction is used to define a region of semiconductor in which the doping character transitions abruptly from p-type to n-type in one direction.
Conceptually, the operating principle of a solar cell can be summarized as follows. Sunlight is absorbed in a material in which electrons can have two energy levels, one low and one high. When light is absorbed, electrons transit from the low-energy level to the high-energy level.
The solar cell is the basic building block of solar photovoltaics. The cell can be considered as a two terminal device which conducts like a diode in the dark and generates a photovoltage when charged by the sun. When the junction is illuminated, a net current flow takes place in an external lead connecting the p-type and n-type regions.
By separating the electrons and holes through a pn-junction, electric current and power can be generated. This is the principle of solar cells. When a p-type semiconductor and an n-type semiconductor are brought together, a built-in potential is established.
If the flow of the majority carriers is also blocked by the passivation layer, the solar cell cannot generate any photocurrent. An effective way to achieve the desired carrier selectivity (to block the minority carriers but allow the majority carries) is the use of a doped layer.

As rays of sun (called photons) enter the p-n junction (especially in the depletion zone), the solar energy (which we normally feel as heat) is absorbed. This gives some of the electrons enough energy to "break free", and creates a new electron-hole pair – that is, a free electron, and an electrically-charged space where an electron should be.
A PN junction is a structure formed by neighboring regions, with different dopings. P type N type semi-conductors. The PN junction is a crucial part of many devices, such as for example, the diode.
