OverviewWorking explanationPhotogeneration of charge carriersThe p–n junctionCharge carrier separationConnection to an external loadEquivalent circuit of a solar cellSee also
The theory of solar cells explains the process by which light energy in photons is converted into electric current when the photons strike a suitable semiconductor device. The theoretical studies are of practical use because they predict the fundamental limits of a solar cell, and give guidance on the phenomena that contribute to losses and solar cell efficiency.
Photovoltaic Source
Where I oR is the dark current at the reference temperature. The other parameters appearing in (PV-2) to (PV-4) are the electron charge q, the Boltzmann constant k, the band-gap energy of the solar cell material e g, and the diode ideality factor n which is between 1-2 (1.3 is typical for silicon solar cells). ...
Solar Photovoltaic Cell Basics
When light shines on a photovoltaic (PV) cell – also called a solar cell – that light may be reflected, absorbed, or pass right through the cell. The PV cell is composed of semiconductor material; the "semi" means that it can …
IV Characterization of Photovoltaic Cells & Panels
The Solar Cell. The solar cell may be represented by the equivalent circuit model shown in Figure 2, which consists of a light-induced current source (I L), a diode that generates a saturation current [I S (e qV/kT - 1)], series resistance (r s), and shunt resistance (r sh).The series resistance is due to the resistance of the metal contacts, ohmic losses in the front …

A solar cell is not really a voltage source or a current source as we usually think of them, but it can power a circuit in the typical voltage-source style. The additional components in the equivalent circuit indicate that the internal current source is not in direct interaction with the load components.
Photovoltaic 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 …

Dark IV Measurements
In the dark case the current flows into the cell and in the illuminated case the current flows out of the cell. Since in the dark case, most of the current crosses the junction under the contact it has a lower series resistance than for the illuminated case. (move the mouse over the image to see dark current flows) 1. J.

The photovoltaic effect was experimentally demonstrated first by French physicist Edmond Becquerel. In 1839, at age 19, he built the world''s first photovoltaic cell in his father''s laboratory. Willoughby Smith first described the "Effect of Light on Selenium during the passage of an Electric Current" in a 20 February 1873 issue of Nature. In 1883 Charles Fritts built the first solid state photovoltaic cell by coati…

Photovoltaic Cells
All PV cells can be modelled as a current source with a diode and two different sources of resistance. Figure 18.6 shows the equivalent circuit diagram for an ideal PV cell. The amount of current produced by the source is directly related to the amount of illumination incident on the cell. In reality a PV cell could be either a current source ...
