Photovoltaics are clean, abundant, and sustainable energy sources that has the potential to fulfill increasing global energy demand. A photovoltaic cell is a device that does the real work of converting solar energy to electrical energy.
It is both very flexible and optically transparent (absorbing 2.3% of incident light from UV to IR), making it ideal for application in thin-film solar cells. Remember that, in order to capture the current out of the absorption region of a solar cell, we have to run wires from the top to the bottom of the cell, passing through our load on the way.
By far the most widely used III-V solar cell is gallium arsenide (GaAs), which has a band gap of 1.42 eV at room temperature. It’s in the range of the ideal bandgaps for solar absorption, and it has the bonus of having a direct-gap absorption, which means that the lattice vibrations don’t matter in deciding whether or not light will get absorbed.
Solar cells consist of several layers. The materials include a conductive layer placed on the substrate, a CIGS semiconductor material, a transparent conductive layer of cadmium sulfide (CdS), then a transparent zinc oxide (ZnO) layer, and an anti-reflective coating of magnesium fluoride (MgF2). In some applications, the CdS layer is eliminated for a cadmium-free finished product.
Aluminum, antimony, and lead are also used in solar photovoltaics to improve the energy bandgap. The improvement in the energy bandgap results from alloying silicon with aluminum, antimony, or lead and developing a multi-junction solar photovoltaic.
Silicon, as we can see, is not an ideal material, but we’ve made it work very well. While its band gap energy (1.1 eV) is in the right set of energies for the solar maximum, there’s still some improvement that can be found by choosing a material a higher absorption coefficient and less temperature dependence.

Silicon is one of the most important materials used in solar panels, making up the semiconductors that create electricity from solar energy. However, the materials used to manufacture the cells for solar panels are only one part of the solar panel itself. The manufacturing process combines six components to create a functioning solar panel.

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 conduct electricity better than an insulator but not as well as a good conductor like a metal.
The solar panels that you see on power stations and satellites are also called photovoltaic (PV) panels, or photovoltaic cells, which as the name implies (photo meaning "light" and voltaic meaning "electricity"), convert sunlight directly into electricity. A module is a group of panels connected electrically and packaged into a frame (more commonly known as a solar …
