  • The difference and comparison of advantages between P-type and N-type components

    The difference and comparison of advantages between P-type and N-type components

    May , 11 2024
    Materials and Structure of a Solar Cell The construction of a particular solar cell is going to vary slightly depending on the specific technology that is utilized to manufacture it. In most solar cells, there is an aluminum back surface field and a P-N Junction. At the P-N junction, there are p-type crystalline silicon wafers that are positively charged and n-type crystalline silicon wafers that ...

  • The difference between the first, second, and third levels of distribution boxes

    The difference between the first, second, and third levels of distribution boxes

    Jun , 22 2024
    What do the primary, secondary, and tertiary boxes of a distribution box mean? This is a relative issue. Let's make a hypothesis: a newly built residential area introduces a 10kV incoming line and builds a distribution room. The outgoing line from the low-voltage end of the transformer is 0.4kV to the distribution cabinet (primary distribution cabinet), then the outgoing line is led to the distrib...
