Construction and working principle of silicon solar cells
Concentration knot浓度结 When two crystalline silicons with the same conductivity type and different doping concentrations are in contact, a concentration junction (also called a gradient junction) with a galvanic double layer and a self-built electric field can also be formed, as shown in Figure 1. For P-type silicon, the contact barrier height eUg at the junction…

Semiconductor PN junction
Two pieces of uniformly doped P-type silicon and N-type silicon with doping concentrations of NA and ND, respectively. At room temperature, the impurity atoms are all ionized, and holes with a concentration of pp and electrons (minority carriers) with a concentration of np are distributed in P-type silicon; electrons with a concentration of nn and holes (minority carriers) with a…
