The most outstanding feature of rubidium is that the electrons outside its nucleus are very unstable, and the energy of visible light is enough to ionize its atoms. Therefore, rubidium is known as the "long eye" metal, which is the most potential photoelectric material in this century. Because of this unique property, rubidium has important applications in many fields. It not only has many traditional applications, but also has some new applications, especially in the field of optoelectronics.

Rubidium is a necessary material for infrared technology

Rubidium crystal has good conductivity and thermal conductivity because of its highly active free electrons. Under the action of a certain wavelength, rubidium electrons can obtain energy and escape from the metal to produce photoelectric effect. The rubidium vacuum tube is installed on the automatic switch door of the hotel or the lobby. When the light irradiates, the current is generated by the photoelectric effect, and the door is closed by the current formed by a certain device. When people walk near the automatic door, the light is blocked, the photoelectric effect disappears, the circuit is disconnected, and the door will open automatically. The stronger the light, the greater the photocurrent, so rubidium is the best material to make photocells and photocells. Rubidium is a necessary material for infrared technology. A series of automatic control can be realized by using these photocells and photocells. For example, rubidium has the ability to absorb infrared rays in fog or at night. The infrared radiation light source is installed on the optical instrument made of rubidium. When the shadow of the aircraft falls on the optical element, it can stop working. Therefore, it can be used as air defense equipment. It can also be made into infrared telescope for military reconnaissance, border patrol, warship night navigation, etc.

Rubidium can be used in solar thin film cells

At present, China's building energy consumption accounts for about 25% of the total social terminal energy consumption, while urban building energy consumption accounts for about 80% of the total building energy consumption. In the future, with the adjustment of economic structure, the migration of population and the emergence of urban agglomerations, the proportion of building energy consumption in the end energy consumption of the whole society will be stable at 35% - 45%. How to reduce the energy consumption of urban buildings? With the development of thin film solar cells, building photovoltaic integration will attract more and more attention. In the future, every building will be a distributed photovoltaic power station.

The successful research and development of rubidium based solar thin film cells and supporting battery devices will be a major revolutionary change in the utilization of solar energy, and will lead the international development direction in this field. According to the current silicon-based solar energy market, the potential market prospect of rubidium based solar thin film cell materials and thermoelectric materials is expected to be more than 10 trillion yuan.

Guangding International Holding Group cooperated with Beijing University of science and technology to carry out the research on RB based perovskite solar thin film cells. At present, it has made a breakthrough, with the photoelectric conversion rate of 21.06%, which is in the leading position in the world. In terms of power generation cost, if the cost per kilowatt hour is controlled within 0.3 yuan, the state subsidy can be completely cancelled and the sustainable development can be achieved. The technology participated in the "2017 China Innovation and entrepreneurship fair" jointly sponsored by China Association for science and technology, national development and Reform Commission, Chinese Academy of engineering, Central Committee of Jiusan Society and Guangdong provincial government. At the same time, he also participated in the exhibition on behalf of academicians of Guangdong Academy of Sciences and CPPCC. If the advanced technology is fully put into operation, it will change the world energy pattern.

Rubidium, a kind of "long eyes" alkali metal, is added into perovskite solar thin film cells. Its characteristics are as follows: first, the photoelectric conversion rate is significantly improved; second, the cost of power generation is significantly reduced; third, the stability is significantly improved; fourth, it is flexible and foldable; fifth, it is easy to use, can be fixed, can also be mobile and portable; sixth, it is energy-saving, environmental protection, pollution-free and renewable.

Due to the scarcity of rubidium resources and the high price, the research of rubidium in China and even in the world is not paid enough attention. Fortunately, with the announcement of Tiantangshan, the world's first independent rubidium deposit in Longchuan, Guangdong, China, the United States, Japan, the United Kingdom, Germany, Israel and other countries have accelerated the pace of research on rubidium resources. It is believed that in the near future, research results will blow out, and industry chains based on rubidium technology will gradually form, especially rubidium's role in the field of optoelectronics Some characteristics, rubidium will be the most potential photoelectric material in this century, there will be an energy revolution, change the world energy pattern.
