As shown in fig. 3, the active region layer 22 includes at least two PN junctions, and P-type semiconductor and N-type semiconductor are formed on the same semiconductor (usually silicon or germanium) substrate by diffusion using different doping processes, and space charge regions called PN junctions are formed at their interfaces. After the P-type semiconductor and the N-type semiconductor are combined, because the free electrons in the N-type region are majority electrons and the holes are almost zero, the holes are called minority electrons, and the holes in the P-type region are majority electrons and the free electrons are minority electrons, the concentration difference of the electrons and the holes is generated at the junction of the P-type semiconductor and the N-type semiconductor. Due to the difference in free electron and hole concentration, some electrons diffuse from the N-type region to the P-type region, and some holes also diffuse from the P-type region to the N-type region. As a result of their diffusion, the P region loses holes, leaving negatively charged impurity ions, and the N region loses electrons, leaving positively charged impurity ions. Ions in the semiconductor cannot move arbitrarily in open circuits and therefore do not participate in conduction. These immobile charged particles form a space charge region near the interface of the P and N regions, and after the space charge region is formed, an internal electric field is formed in the space charge region due to the interaction between positive and negative charges, and the direction of the internal electric field is from the positively charged N region to the negatively charged P region. Silicon as a semiconductor material also has an important property that when light is applied, electrons in the outer layer of silicon get the ability to move freely from the light, becoming free electrons and leaving a hole in place, forming an electron-hole pair. If the group of electron-hole pairs are generated in the area of the built-in electric field of the PN junction, under the action of the electric field force, the holes move to the P area, and the electrons move to the N area, so that a potential difference is generated at two ends of the PN junction, and at the moment, because the first electrode layer 21 and the second electrode layer 23 are arranged, current is generated, when sunlight irradiates, light energy excites electrons in silicon atoms to generate electron and hole convection, the electrons and the holes are influenced by the built-in electric field, are respectively attracted by the N type semiconductor and the P type semiconductor, are gathered at two ends and are connected by the first electrode layer 21 and the second electrode layer 23 to form a loop, and the conversion from light energy to electric energy can be realized. Wherein, an isolation layer 24 is arranged between two adjacent PN junctions, and the isolation layer 24 is used for isolating the two adjacent PN junctions and preventing the adjacent PN junctions from being conducted to influence each other.
