What determines generated voltage and current in solar cell?

Click For Summary
SUMMARY

The generated voltage and current in solar cells are primarily influenced by illumination, bandgap of the material, temperature, and quantum efficiency. Additionally, the doping levels of n-type and p-type materials significantly affect the generation and concentration of charge carriers, which in turn influences the quasi-Fermi levels, bandgap, and potential difference. Understanding these factors is crucial for optimizing solar cell performance. For further exploration, resources such as Wikipedia articles and specialized textbooks on solar cell technology are recommended.

I know illumination, bandgap of the material, temperature, quantum efficiency all have an effect on the current and voltage of a solar cell.

But what about the doping, and the generation and concentration of charge carriers? A semiconductor can only generate a finite number of charge carriers, dependent on how doped the n and p type materials are.

The doping of the semi conductor also effects the quasi fermi levels, which will effect the bandgap and the potential difference (voltage).

I think your questions require answers too detailed for an Internet forum.

Wikipedia has articles on solar cells, and solar cell research. At the bottom of each article is a list of links suitable to dig further.

You might also search for textbooks on the subject.

Good luck,
