How a Solar Cell Works
A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their outer energy level than does silicon. Because boron has one less electron than is required to form the bonds with the surrounding silicon atoms, an electron …

Bias of PN Junctions
A small increase in the drift current is experienced due to the small increase in the width of the depletion region, but this is essentially a second-order effect in silicon solar cells. In many thin film solar cells where the depletion region is around half the thickness of the solar cell the change in depletion region width with voltage has a ...
Open-Circuit Voltage
The above equation shows that V oc depends on the saturation current of the solar cell and the light-generated current. While I sc typically has a small variation, the key effect is the saturation current, since this may vary by orders of magnitude. The saturation current, I 0 depends on recombination in the solar cell. Open-circuit voltage is then a measure of …

Bypass Diodes
In practice, however, one bypass diode per solar cell is generally too expensive and instead bypass diodes are usually placed across groups of solar cells. The voltage across the shaded or low current solar cell is equal to the forward bias voltage of the other series cells which share the same bypass diode plus the voltage of the bypass diode.
Photovoltaic effect
The photovoltaic effect is a process that generates voltage or electric current in a photovoltaic cell when it is exposed to sunlight. It is this effect that makes solar panels useful, as it is how the cells within the panel convert sunlight to electrical energy. The photovoltaic effect was first discovered in 1839 by Edmond Becquerel.
