The phosphorus atom lacks an electron and becomes a positively charged phosphorus ion. Since phosphorus ions act as discharge agents in the crystal, pentavalent phosphorus is called a host impurity, also known as an N impurity.<\/p>\n<p>(3) When trivalent boron is doped into the pure silicon lattice, there is one less free electron, so one electron must be obtained from the valence bond of the silicon atom to fill it. At the same time, a hole is generated on the silicon atom, making it negatively charged. Therefore, trivalent boron is called the main impurity, also called P impurity.<a href=\"https:\/\/www.ray-tron.com\/en\/\" data-internallinksmanager029f6b8e52c=\"15\" title=\"Solar panels\">Solar Cells<\/a>Semiconductor materials are a special substance between conductors and insulators. Like atoms of any substance, semiconductor atoms are composed of a positively charged nucleus and a negatively charged electron. When subjected to external energy, these electrons become free electrons from the orbit and leave a &quot;hole&quot; in their original position. If boron, gallium and other elements are added to silicon crystals, it becomes a hole-type semiconductor, usually represented by the symbol P; if phosphorus, arsenic and other elements are added to release electrons, it becomes an electron-type semiconductor, represented by the symbol N; if these two semiconductors are combined, a PN junction will be formed at the intersection. The PN junction of a solar cell is like a wall that hinders the movement of electrons and holes. When a solar cell is irradiated by sunlight, electrons receive light energy and move to the N-type region, making the N-type region negatively charged, while holes move to the P-type region, making the P-type region positively charged. In this way, the PN junction will generate an electromotive force at both ends, which is usually called voltage. This phenomenon is the &quot;photovoltaic effect&quot; mentioned above.<\/p>\n<p>Can produce<a href=\"https:\/\/www.ray-tron.com\/en\">Photovoltaic effect<\/a>There are many kinds of materials, such as: single crystal silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, copper indium selenide, etc. Their power generation principles are basically the same. Their power generation principles are basically the same. Now take crystalline silicon as an example to describe the photovoltaic power generation process. When light shines on the surface of the solar cell, some photons are absorbed by the silicon material; the energy of the photons is transferred to the silicon atoms, causing the electrons to migrate and become free electrons gathered on both sides of the PN junction, forming a potential difference. When the external circuit is connected, under the action of voltage, current will flow through the external circuit and generate a certain output power. The essence of this process is: the process of converting photon energy into electrical energy.<\/p>","protected":false},"excerpt":{"rendered":"<p>(1) In order to obtain the desired material, people add certain impurities to semiconductor materials.
