The fundamental distinction between P-type and N-type solar cells is the number of electrons. A P-type cell often dopes its silicon wafer with boron, which has one fewer electron than silicon (forming the cell positively charged).
There are two main types of solar cells used in photovoltaic solar panels – N-type and P-type. N-type solar cells are made from N-type silicon, while P-type solar cells use P-type silicon. While both generate electricity when exposed to sunlight, N-type and P-type solar cells have some key differences in how they are designed and perform.
N-type cells have a lower temperature coefficient than P-type cells, therefore they are less influenced by high temperatures, resulting in greater power generation performance and suitability for places with superior irradiation conditions.
N-type and P-type solar cells generate electricity through the photovoltaic effect. This process relies on the semiconductor properties of silicon, which is the main material used in solar cells. In an N-type cell, phosphorus or arsenic atoms are added to the silicon, providing extra electrons. These electrons can move freely through the material.
P-type Solar Cells (1) In terms of bifacial rate, N-type solar cells have a higher bifacial rate than P-type solar cells. The PERC (P-Type) cell has a bifacial rate of 75%, TOPCon (N-Type) has a bifacial rate of 85%, and HJT (N-Type) has a bifacial rate of approximately 95%.
P-type solar cells use P-type silicon wafers as their raw material and are primarily manufactured using traditional Al-BSF (Aluminum Back Surface Field) technology and PERC (Passivated Emitter Rear Contact) technology. P-type solar panels have a prominent bulk c-si area that is negatively charged due to boron doping.

According to hjtpv , a typical P-type solar module may have a temperature coefficient of around -0.5%/°C, meaning its power output decreases by 0.5% for every 1°C increase in operating temperature. In contrast, N-type cells can have temperature coefficients as low as -0.26%/°C, nearly half that of P-type.
P-type solar panels tend to have a higher temperature coefficient than N-type solar panels. This means that their output power decreases more rapidly as the temperature increases. This can be a …
