The only difference in a solar cell is that the electron loss (into the conduction band) starts with absorption of a photon. In 1991, Gratzel and Regan realized a low-cost solar cell that used liquid dye on a titanium (IV) oxide film. The overall scheme is shown below, and has come to be known as a general approach of dye-sensitized solar cells.

Cell Fabrication – Silicon wafers are then fabricated into photovoltaic cells. The first step is chemical texturing of the wafer surface, which removes saw damage and increases how much light gets into the wafer when it is exposed to sunlight. The subsequent processes vary significantly depending on device architecture.
Photovoltaics (often shortened as PV) gets its name from the process of converting light (photons) to electricity (voltage), which is called the photovoltaic effect.This phenomenon was first exploited in 1954 by scientists at Bell Laboratories who created a working solar cell made from silicon that generated an electric current when exposed to sunlight.
Photovoltaic Cell: Photovoltaic cells consist of two or more layers of semiconductors with one layer containing positive charge and the other negative charge lined adjacent to each other.; Sunlight, consisting of small packets of energy termed as photons, strikes the cell, where it is either reflected, transmitted or absorbed.

When a solar PV cell receives the impact of a photon can displace one electron from its outer layers creating an electric current. This phenomenon is called the photovoltaic effect. There are many types of solar cells, such as thin-film solar cells. A thin-film solar cell consists of a cell made by depositing one or more thin layers of PV material.
Solar cells are the electrical devices that directly convert solar energy (sunlight) into electric energy. This conversion is based on the principle of photovoltaic effect in which DC voltage is generated due to flow of electric current between two layers of semiconducting materials (having opposite conductivities) upon exposure to the sunlight [].
