6 FAQs about [There is light under the photovoltaic panel]
What is the 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.
Where does the photovoltaic effect occur?
The photovoltaic effect occurs in solar cells. These solar cells are composed of two different types of semiconductors - a p-type and an n-type - that are joined together to create a p-n junction. To read the background on what these semiconductors are and what the junction is, click here.
How does light intensity affect the trough solar photovoltaic cell?
It is concluded that when the light intensity gradually increases, the open circuit voltage and short-circuit current of the trough solar photovoltaic cell gradually increase; the open circuit voltage and short-circuit current of the trough solar photovoltaic cell gradually increase.
Are solar photovoltaic cell output voltage and current related?
Through the above research and analysis, it is concluded that the output voltage, current, and photoelectric conversion rate of solar photovoltaic cells are closely related to the light intensity and the cell temperature.
What happens when light is absorbed in a photovoltaic cell?
If you remember, the photovoltaic effect happens when light energy is absorbed by an electron. In the case of a photovoltaic cell, the incident light is absorbed by an electron in the depletion region. It turns out that, for this energy to be captured in a photovoltaic cell, it has to have a certain energy. What is the Band Gap in Photovoltaics?
Why is the top layer of a photovoltaic cell kept thin?
The top layer material is kept thin because we want light to be able to pass through it to strike the depletion region. If you remember, the photovoltaic effect happens when light energy is absorbed by an electron. In the case of a photovoltaic cell, the incident light is absorbed by an electron in the depletion region.
