About the preparation of solar cells

Source: 2020 - 04 - 11:18:57 click traffic time on the preparation of solar cell as the earth's oil energy consumption, the environmental protection consciousness of people, the demand for clean energy more and more strong. The solar cell is a photovoltaic energy conversion device, it can convert light energy into electrical energy, in the conversion process does not produce any pollutants. It is one of the most important clean energy. Compared with other clean energy, photovoltaic properties of semiconductor can be used for solar energy conversion, possesses the advantages of footloose. As long as there is the sun on the earth, the solar cell can be used to convert the sun's energy and the energy directly. As the solar power distributed to the promotion of urban and rural areas in China. Single dark blue solar power station has not meet the needs of people beautify. If distributed solar power stations can be formed pattern need through a combination of different colors of the solar cell, it will be for distributed power stations, advertising and decoration effect, greatly reduce the cost of power station construction, to speed up promote the distributed power station, to achieve the purpose of energy saving and emission reduction. In this paper, through the study on the properties of different color battery, battery preparation process are discussed with the battery and battery performance, provide reference for color design of solar power plants. How color solar cells work color solar cells by using the reflection of different thickness of the membrane to the reflected light, forming different color, the use of light interference principle. As shown in figure 1, different colors of light have different wavelengths. When different thickness of the silicon nitride thin film deposition on solar cells, they reflect different colors of light, so the battery will present a different color. Study the preparation technology of different color battery and battery performance. The results showed that the deposition pressure for 1800 mTorr and refractive index of 2 battery. 1. Different color battery open circuit voltage change less than 0. 4 v, and short-circuit current changes greater than zero. 5ma。 Which has the function of decoration, therefore, the solar cell module should be concurrent design, in order to achieve the best efficiency of modules.
