The I PV PV current increases in proportion to the incident irradiance. If the spectrum does not change, the I PV is directly proportional to irradiance I PV = C G G.Then, at a constant temperature, the V OC increases with irradiance logarithmically, as follows from Eq.

What is a photovoltaic (PV) cell?
A photovoltaic (PV) cell is an energy harvesting technology, that converts solar energy into useful electricity through a process called the photovoltaic effect. There are several different types of PV cells which all use semiconductors to interact with incoming photons from the Sun in order to generate an electric current.
How does a photovoltaic cell work?
The working principle of a photovoltaic (PV) cell involves the conversion of sunlight into electricity through the photovoltaic effect. Here's how it works: Absorption of Sunlight: When sunlight (which consists of photons) strikes the surface of the PV cell, it penetrates into the semiconductor material (usually silicon) of the cell.
