[0031] The water spraying assembly is arranged below the water storage tank 18 and is communicated with the water storage tank 18.

[0032] The photovoltaic panel, also known as a solar cell panel, works on the principle of the photovoltaic effect, which is a physical phenomenon that when light shines on a semiconductor material, it can excite electrons, thereby generating an electric current. The following is a detailed explanation of the working principle of the photovoltaic panel:

[0033] Photovoltaic effect:

[0034] When sunlight (especially the visible light and ultraviolet part) shines on a semiconductor material (such as silicon), photons (particles of light) will interact with atoms in the semiconductor. If the energy of the photon is large enough, it can excite an electron from the valence band of the semiconductor material to the conduction band, leaving a hole (positive charge) in the valence band. This process is called the generation of photo-generated carriers.

[0035] Separation and collection of carriers:

[0036] In a photovoltaic cell, there is usually a thin layer of P-type semiconductor (rich in holes) and a layer of N-type semiconductor (rich in free electrons) connected together through a PN junction. When photo-generated carriers are generated, electrons will be attracted by the N-type semiconductor, while holes will be attracted by the P-type semiconductor. In this way, electrons and holes accumulate on both sides of the PN junction, forming an internal electric field.

[0037] Generation of electric current:

[0038] Under the action of the internal electric field, electrons will try to flow from the N-type semiconductor to the P-type semiconductor, while holes will try to flow from the P-type semiconductor to the N-type semiconductor. However, due to the presence of the PN junction, electrons and holes cannot directly cross the junction region. Therefore, they will form a current near the junction region, which can be collected and utilized through an external circuit.

[0039] Structure of photovoltaic panel:

[0040] Photovoltaic panels are typically composed of many small photovoltaic cells that are connected in series or parallel to increase the output voltage or current. Each photovoltaic cell contains a PN junction and electrodes for collecting and conducting the current.

[0041] SUMMARY

[0042] In summary, photovoltaic panels work on the principle of the photovoltaic effect, generating electricity through the generation, separation, and collection of photo-generated carriers in semiconductor materials.
