Difference Between N Type And P Type Solar Panel

The main difference between p type and n type solar cells is the number of electrons.

Difference between n type and p type solar panel.

The p type solar cell is the solar cell structure everyone knows. Thin film technology costs less than mono or poly panels but is also less efficient. Monocrystalline p type solar modules use cells wafers that are czochralski grown and block cast p type polycrystalline cells wafers to a lesser extent suffer from light induced degradation lid. It held the biggest size of the market for the last four decades.

But there is another choice very few people are aware they are making but it occurs when they select high end high efficiency solar panels that use n type solar cells over panels that use the much more common but lower efficiency p type solar cells. A p type cell uses boron which has one less electron than silicon making the cell positively charged. An n type cell is doped with phosphorus which has one more electron than silicon making the cell negatively charged. The advantages of n type cells.

A p type cell usually dopes its silicon wafer with boron which has one less electron than silicon making the cell positively charged. First a solar cell is a crystalline silicon wafer covered with various chemicals to allow electricity generation. Monocrystalline p type solar modules use cells wafers that are czochralski grown and block cast p type polycrystalline cells wafers to a lesser extent suffer from light induced degradation lid. While p type mono and multi perc are being developed n type wafers capacity is also on the rise itrpv forecasting a market share gain albeit still well under the major technologies.

An n type cell is doped with phosphorus which has one more electron than silicon making the cell negatively charged. Polycrystalline solar cells are blended from multiple silicon sources and are slightly less efficient. A p type cell usually dopes its silicon wafer with boron which has one less electron than silicon making the cell positively charged. Lid occurs when oxygen impurities in the silicon wafer react with the doped boron in the first few hours weeks of illumination of the cell.

Monocrystalline solar cells are more efficient because they are cut from a single source of silicon. What differentiates n type and p type solar cells is the number of electrons. The advantages of n type cells. N type cells are more resistant to light induced degradation than p type cells.
