    What do you mean by the photoelectric effect? Is it the Eistan photoelectric effect? In the case of a university course, the photoelectric effect includes the photovoltaic effect.

    There are many kinds of photoelectric effects, according to whether electrons are emitted, the photoelectric effect is divided into internal photoelectric effect and external photoelectric effect, the internal photoelectric effect includes the photoconductive effect, the photovoltaic effect, the photon traction effect and the photomagnetoelectric effect, etc., the external photoelectric effect includes the photoelectric emission effect, that is, the Einstein photoelectric effect in high school physics, I don't know if you refer to this, if so, I can tell you the difference, the first point is that the material that produces the photovoltaic effect can only be a semiconductor, and the photoelectric emission effect material can be a metal, The second point photovoltaic effect is the minority carrier process, which is the potential difference between the two ends of the pn junction after a small number of carriers in the semiconductor absorb photons, and the photoelectric emission effect is that the semiconductor or metal radiates free electrons under the excitation of photons, and escapes from the surface after overcoming the surface barrier and emits electrons outward, the third is that the carriers cannot leave the material in the photovoltaic effect, and the latter can leave the material, the fourth is that the former has a certain absorption spectrum for the spectrum and is related to the light intensity, while the latter has a cut-off wavelength electron escape speed independent of the light intensity, Only frequency is related, you can go to the encyclopedia to check it, we just happened to learn the course of photoelectric detection and signal processing, so I know, I hope it can help you! (I don't know what the photoelectric effect you are referring to, I don't think you understand the concept of the photoelectric effect, maybe you are referring to the Einstein photoelectric effect in high school books, you say something specific, I will help you answer.) )

    Explanation of photovoltaic effect "photovoltaic effect", referred to as "photovoltaic effect", English name: photovoltaic effect. Refers to the phenomenon that light causes a potential difference between different parts of an inhomogeneous semiconductor or semi-unbridled conductor and a metal.

    It is first of all the process of converting photons (light waves) into electrons and light energy into Tanzhou electric energy. Secondly, it is the formation of the voltage process. With voltage, it's like building a dam, and if the two are connected, the crack will form a loop of current.

    The difference between the photovoltaic effect and the photoelectric effect is that the photoelectric effect is actually the pre-split liti of the photovoltaic effect, and the photovoltaic response is the photoelectric effect acting on the special place of the semiconductor, thus creating an electric potential difference.

    The main differences between the two are the following:

    1. The material that produces the photovoltaic effect can only be semiconductors, while the material with the photoelectric emission effect can be metal. Be careful.

    2. The photovoltaic effect is a minority carrier process, which is the potential difference between the two ends of the p-n junction after a small number of carriers in the semiconductor absorb the photons, and the photoelectric emission effect is that the semiconductor or metal radiates free electrons under the excitation of photons, and escapes from the surface to emit electrons after overcoming the surface barrier.

    3. In the photovoltaic effect, the carriers cannot leave the material, and the latter can leave the material.

    4. The former has a certain absorption spectrum for the spectrum and is related to the light intensity, while the latter has a cut-off wavelength and the electron escape rate has nothing to do with the light intensity, only the frequency.

    Introduction to the photovoltaic effect and the photoelectric effect:

    The photovoltaic effect, or photovoltaic effect in English, mainly refers to the fact that when light irradiates a substance, photons will excite and replace the electrons in the substance. These electrons are clustered in a certain region and constitute the photovoltaic potential phenomenon. As early as 1839, the French scientist Becquerel discovered that light could cause potential differences between different parts of semiconductor materials.

    This phenomenon came to be known as the "photovoltaic effect", or "photovoltaic effect" for short.

    Solar photoelectric conversion refers to the process by which photons of solar radiation energy are converted into electrical energy through semiconductor materials, commonly known as the "photoelectric effect". Solar cells are made from this effect, that is, objects are created by absorbing photons. The photoelectric effect is an important and miraculous phenomenon in the source theory of matter.

    Under the irradiation of electromagnetic waves above a certain frequency, the electrons in some substances will be excited by photons to form an electric current, that is, photogenerated electricity. The photovoltaic effect refers to uneven illumination.

    The photoelectric conversion of solar energy refers to the process of converting the sun's radiant energy photons into electrical energy through semiconductor materials, which is usually called the "photogenerated voltaic effect", and the solar cell is made by using this effect, which refers to the phenomenon of electromotive force generated by the object due to the absorption of photons, and is an effect of electromotive force and current generated by the change of charge distribution state in the object when the object is illuminated.

    Strictly speaking, there are two types: one is that occurs in uniformity.

    Inside semiconductor materials; One is:

    occurs at the interface of semiconductors. Although there are some similarities between them, the specific mechanisms that produce these two effects are different. The former is often referred to as the Dampie effect [1], and the light.

    The meaning of the voltaic effect is limited to the latter category.

    When a junction formed by two different materials is irradiated with light, an electromotive force is generated on the junction. Its process is the material first.

    The energy of the photons is absorbed, creating an equal number of positive and negative charges, which then migrate to each side of the junction to form an electric layer. Although the photovoltaic effect is not instantaneous, its response time is quite short.

    To put it simply, light shines on an object that generates an electric current.

    In quantum science, it is the process by which an object absorbs photons and converts them into electrons.

    The photoelectric effect is the emission of electrons when light hits the surface of an object.

    The photovoltaic effect is when light hits the p-n junction to create a potential difference.

    With the large-scale expansion of photovoltaic power stations, high-quality power station construction land resources are scarce, the comprehensive income of power stations needs to be improved, and photovoltaic power stations have a trend of integration with the primary industry. For example, the artificial solar multi-layer high-density soilless planting plant adopts a new energy-saving light source to promote plant photosynthesis, and uses multi-layer superimposed three-dimensional plants to improve land use efficiency. Another example is the optical model of the agricultural science and technology greenhouse, the roof of the greenhouse is installed with photovoltaic cells or collectors, flexible and light transmission, suitable for the growth of certain crops and side code cash crops, but also to achieve industrialization and efficient output of land.

    The combination of photovoltaic and tailings treatment, circular economy construction or comprehensive ecological management in abandoned mining subsidence areas enables the restoration of the ecological environment of abandoned land. The combination of photovoltaic and traditional water treatment municipal facilities can effectively reduce the cost of water treatment and the carbon emission per unit of water treatment through the photovoltaic water model.
