The basic structure of a crystalline silicon PV cell consists of a layer of n-type (negative) silicon on one side and a layer of p-type (positive) silicon on the other side. The p-type silicon layer contains boron, which has one less electron than silicon and creates a positive charge, while the n-type silicon layer contains phosphorus, which ...
Flexible silicon solar cells with high power-to-weight ratios
Design of an electrode pattern. Generally, a crystalline silicon solar cell has metal electrodes on the front and rear side of the surface. The electrodes consist of Ag fingers and busbars on the front side, Al electrodes and Ag pads (or busbars) on the rear side; each electrode has its own function.

The p-type crystalline silicon wafers have occupied most of the solar cell market today. However, modules made with n-type crystalline silicon wafers are actually the most efficient modules up to date. This is because the material properties offered by n-type crystalline silicon substrates are suitable for higher efficiencies.
