Working Principle: The working of solar cells involves light photons creating electron-hole pairs at the p-n junction, generating a voltage capable of driving a current across a connected load.

The diagram illustrates the conversion of sunlight into electricity via semiconductors, highlighting the key elements: layers of silicon, metal contacts, anti-reflective coating, and the electric field created by the junction between n-type and p-type silicon. The solar cell diagram showcases the working mechanism of a photovoltaic (PV) cell.
simple conventional solar cell structure is depicted in Figure 3.1. Sunlight is incident from the top, on the front of the solar cell. A metallic grid forms one of the electrical contacts of the diode and allows light to fall on the semiconductor between the grid lines and thus be absorbed and converted into electrical energy.
The antireflection coating Most solar cells rely on a thin layer of a dielectric (an antireflection coating) to reduce the reflection of light from the front surface of the cell. This section gives a brief description of the reflection of light from a bare semiconductor, and from a semiconductor with a single-layer antireflection coating.
The band diagram corresponds the usual situation encountered in CdTe and CIGS solar cells where an n-type wide-gap window and a p-type emitter are the most common arrangements. Similarly to the p–n junction the built-in potentials Vbi (A) and Vbi (B) on the two sides of the junction can be determined by solution of the Poisson equation (see Eq.
The Physics of the Solar Cell Semiconductor solar cells are fundamentally quite simple devices. Semiconductors have the capacity to absorb light and to deliver a portion of the energy of the absorbed photons to carriers of electrical current – electrons and holes.
To increase the amount of incident light energy and hence generated current, the junction area is kept large. Three processes—generation, separation, and collection via the back contact of electron-hole pairs—combine to produce the electromagnetic field (emf) produced by a solar cell. The solar cell circuit diagram is shown below.
