| Shortages of energy and environmental pollution have forced people to look for a new clean, non-polluting and renewable energy. The solar cell in some extent to meet the requirements of this new energy. In all cells in which the polysilicon material to the fore, had come to dominate the market. The polysilicon material for high oblique incidence of light reflectance defects in a large part of the energy is reflected into the air, wasted. Thus forcing people to continue to improve battery technology to minimize reflection losses.Black silicon material mentioned in this article is the use of reactive ion etching silicon surface SF6/O2formed, so the preparation method known as plasma immersion ion implantation (PⅢ). PⅢ technology is the mechanism to produce F*SF6group reacts with silicon production SiF4gas from the etching effect, O*radicals and SiF4formation of passivation (SiOxFy) protect the sidewall etch and passivation role in both the competitive process in the formation of black silicon porous structure. Diameter and depth of the hole was1Lm and8Lm, studies have shown that the formation of black silicon harsh conditions, require low temperatures (below-80℃), working pressure range is narrow. The black silicon material is applied to this porous structure of the solar cell module, the multi-angle greatly reduces the absorption characteristics of the surface reflection of light, greatly improving the efficiency of the cell. Meanwhile, the conventional photovoltaic power generation module in order to achieve maximized, with a certain angle during installation, in the course of the component, part of the light is still reflected from the surface into the air, waste.In order to achieve maximum power output,common PV modules will have a certain angle,but still some light will be reflected from the surface of the common PV modules into the air and waste,This paper presents a reflective plate structure with efficient black silicon solar modules, multi-angle light-absorbing black silicon components with reflective plate structure can take advantage of reflected light. The angle of the reflectors and black silicon component were simulated in this paper, the results show that when the assembly angle of PV module is34℃, the optimum angle of the reflective plate is16.5°, in this case,battery’s power generation increased by about39%under the same illumination conditions,In this paper, the principle of distributed power generation system components, design, and network and storage systems were studied, studies have shown that the lower area of distributed generation systems and environmental requirements, as long as a sunny place to set up. Second, the size of its power is not limited to, able to adapt to different load or residential electricity. Therefore, the greatest degree of distributed generation system will meet the demand for new energy sources. Solar carport project-while the design of distributed power generation systems with efficient black silicon reflector assembly is installed. The project uses250Wp crystalline silicon solar cell modules, using165mm×99mm solar cells, photoelectric conversion efficiency of15.59%, taking60packaged into solar modules installed capacity of16.5KWp. Project is expected to put into the annual generating capacity of35200kwh. According to forecasts, the project is the potential energy saving effect, compared with the average energy consumption and power plant emissions, equivalent substitution of coal5956.5t annual emission reduction can be achieved while CO214600t, SO2142.8t, NOx41.7t. Construction of the project will save energy, reduce harmful emissions and make a positive contribution to the work. Further elaborated the significance of distributed power generation systems for human socio-economic development and energy transformation. |
