Differentiate Between Solar Panel And Solar Cell

All solar cells have both n type and p type with the great majority having one surface n type and one surface p type.

Differentiate between solar panel and solar cell.

For example if the efficiency of a monocrystalline cell is about 2 greater than the polycrystalline cell say 17 vs. 15 the difference is about 10 watts w per regular panel 270 w mono. The main difference between the two technologies is the type of silicon solar cell they use. It is the junction between the n and the p type regions that creates the step in the energy levels that leads when illuminated to the 600 mv potential difference between the electrons entering the p type layer and leaving the n type layer.

Monocrystalline solar panels have solar cells made from a single crystal of silicon while polycrystalline solar panels have solar cells made from many silicon fragments melted together. Space areas between the solar cells. A cell on its own doesn t produce much power and a number of cells together need the protection and stability that the panel offers. A solar cell panel has then a smaller solar active area compared to its total area than a single solar cell i e.
