N-type or P-type Cells: What technology to choose

Choosing the PV modules affordable for your installation needs to consider power output, efficiency, and aesthetics, but the inner layer of the cells with N-type or P-type is a significant factor impacting the product’s general performance.

Indeed, a select photovoltaic (PV) module featuring a P-type solar cell or an N-type solar cell can make a difference in the performance and lifespan of the module.

P-type and N-type solar panels: what to choose

Most P-type and N-type solar cells are the same, with slight and very subtle manufacturing differences for N-type and P-type solar panels.  The essential aspect of the difference between P-type and N-type solar panels is the doping used for the bulk region and the emitter. 

P-type solar panels have a high resistance to radiation and degradation. This conclusion came from the 1950s when in space photovoltaic application technology applied boron. The solar industry kept the momentum going, using this well-researched technology by lowering prices to produce better P-type solar panels for terrestrial applications. 

Even though many manufacturers usually apply boron for doping P-type solar panels, it can cause a boron-oxygen defect and lead to a performance decrease.
