Solar cells (photovoltaic diodes) are frequently used in many electronic equipment today.
One might think that the amount of energy that can be obtained from photovoltaic diodes might be limited. This is partly true. However, solar cells are also used in many high energy applications.
With the spread of the zero carbon terminology, which is on the agenda worldwide, the importance of clean energy is constantly increasing. However, the areas of use of solar cells are constantly expanding.
Photovoltaic diodes, like other diodes, are formed by the combination of p and n type semiconductors. In one of these semiconductors, an excess of electrons is created, while in the other semiconductor, electrons are reduced. The sun’s rays interact with the semiconductors, creating electron movement and a voltage difference between the semiconductors.
Solar Cell (Photovoltaic) Diode Applications
Solar cells have a wide range of uses and sizes.
Energy support systems such as Powerbank: Solar cells can be used in Powerbank applications to use the stored energy for longer periods of time.
Systems that are far from energy: Some electrical systems may be located far from the electricity grid. Solar panels can be used to energize these systems. After the electrical energy is generated as DC voltage, it is converted into AC voltage using inverters depending on the characteristics of the systems to be energized.
Home and industrial systems: Solar panels can also be used in household and industrial applications and their share in total energy use is increasing day by day.
Bypass Diodes at Solar Panels
Solar panels are generally able to produce maximum energy when there is full insolation. However, it is not possible to have full sun continuously. In some cases, either no energy can be produced or it is not enough for the systems they are used in. In these cases, the voltage generated from solar panels must be eliminated using bypass diodes.
