What are Single-junction Solar Cells? How are they Different from Conventional Solar Cells?

 

This question is part of the Super Big Solar Panel FAQ from Solar Mango, where expert answers to over 100 important questions on solar panels are provided.

 

Almost all the solar panels that are being used commercially today are made of single junction cells.

So, what are single junction solar cells?

Single-junction solar cells have just one p-n junction, as against multi-junction solar cells, which have more than one p-n junction. p-n junction refers to the boundary between two types of semiconductor material. One type is called the p-type and the other is called the n-type.

In a typical solar cell, one side of the cell is doped with boron (the p type), and the other side is doped with phosphorus, the n-type. The p-n junction generates current and voltage due to the “built-in” electric field at the junction of the p-type and n-type material.
