The photovoltaic (PV) cell is the smallest building block of the PV solar system and produces voltages between 0.5 and 0.7 V. It acts as a current source in the equivalent circuit. The amount of radiation hitting the cell determines how much current it produces. The equivalent circuit of an ideal PV cell consists of a diode and a parallel current source. In order to express

The model will be used to derive the so-called solar cell equation, which is a widely used relation between the electric current density I leaving the solar cell and the voltage V across the converter. For this purpose, we use the relation for generated power P = I ⋅ V and Eq. (127) and we obtain: By using Eqs. (128), (129) we derive:
The behavior of solar cells and modules under various operational conditions can be determined effectively when their intrinsic parameters are accurately estimated and used to simulate the current-voltage (I-V) characteristics. A new estimation approach for determining the I–V characteristics of solar cells is presented in the article 'Simple and efficient estimation of photovoltaic cells and' published in Solar Energy in 2011.
The quantum efficiency of a solar cell is defined as the ratio of the number of electrons in the external circuit produced by an incident photon of a given wavelength. Thus, one can define external and internal quantum efficiencies (denoted by EQE (λ) and IQE (λ), respectively).
For this reason, the IV measurement must be carefully designed for high efficiency solar cells. Multiple approaches exist: Increase of measurement time by flashing the device multiple times over segmented voltage ranges and reconstruct the IV curve in post-processing.
The I–V characteristic of a solar cell in practice usually differs to some extent from the ideal characteristic (1). A two-diode model is often used to fit an observed curve, with the second diode containing an ‘ideality factor’ of 2 in the denominator of the argument of the exponential term.
