In an N-type cell, electrons are the majority charge carrier. They flow from the N-type layer on top to the metal contact, generating electricity. In a P-type cell, the absence of electrons (holes) are the majority charge carrier. They flow from the P-type base to the N-type emitter.
The n-type tends to be a better choice due to reducing LID (Light Induced Degradation) & increasing durability and performance compared to the p-type. n-type: Silicon with 5 valence electrons impurities produces n-type semiconductors in which one extra electron contributes to increasing the electrical conductivity of the semiconductor.
To summarize, the main aspect that makes P-type and N-type solar cells different is the doping used for the bulk region and for the emitter.
According to research from Chint Global, N-type panels have an efficiency of around 25.7%, compared to 23.6% for P-type panels. There are a few reasons N-type cells tend to be more efficient: The thinner emitter layer in N-type cells reduces recombination losses, allowing more current to be collected.

The resulting optimized flower-like structure, composed of interlaced nanoflakes derived from MOFs, greatly improved the active sites, porosity, and functionality of the electrode materials. The ZnO/NiO-350 electrode exhibited superior electrochemical activities for supercapacitors, compared to the parent MOF, bare n-type, and p-type counterparts.
