In the mobile Internet era, the client's use of a very important part in its use of time, no matter how excellent performance, if the mobile phone, tablet PC or smart products in the absence of the rest of the power cable can not boot the case that they can not be effectively applied.
The need to improve the battery life on a method, a way to reduce the energy usage of the same time, like iPad, save all you can save power consumption mode, save all you can save space, but for the rapid development of IT products indeed in terms of discomfort. Another method is to improve battery performance, the product can provide a more sustainable life, the development of mobile Internet mobile power needs support in this area are mainly thin-film battery technology, piezoelectric materials technology, wireless charging technology, the following for everyone to make a detailed introduction.
Thin film batteries
Solar energy is easily accessible to a source of energy. Application of solar energy in human history, it has sought to question. Monocrystalline silicon solar cells at this stage, although large-scale applications and industrial production dominates, but also exposed a number of shortcomings, which the main problem is the high cost. By both monocrystalline silicon solar cell material prices and the impact of the preparation process, to further significantly reduce the cost of silicon solar cells is very difficult.
So have their substitutes thin film solar cells, including amorphous silicon thin film solar cells, copper indium selenide and cadmium telluride thin-film cells, polycrystalline silicon thin-film solar cells. Amorphous silicon thin film solar cells is the most important advantages of low cost and convenient preparation, due to its photoelectric conversion efficiency as a continuation of the attenuation of the illumination time, it is obvious instability.
As for copper indium selenide and cadmium telluride thin-film silicon cell efficiency than amorphous silicon thin film batteries is high, lower costs than single crystal silicon cells, and ease of mass production, there is no sharp drop in the efficiency problem, seems to be an amorphous silicon thin film batteries species better alternatives. Polycrystalline silicon thin film is generated in the battery production process large contamination should not be ignored, the raw material selenium, indium, tellurium and metals are relatively rare, further reducing the cost of a smaller space.
Polycrystalline silicon thin film batteries due to the amount of silicon used in less than silicon, and inefficient plummeted problem, and use may be prepared on cheap substrates, the cost is expected to be much lower than the monocrystalline silicon cells, laboratory efficiency reached 18%, far higher than the amorphous silicon thin film cell efficiency. Therefore, the polycrystalline silicon thin film battery is considered to be the most likely alternative to silicon cells and amorphous silicon thin film solar cell generation, has now become an international solar hot research field.
Thin film solar cell production costs are lower, its market share continued to grow in recent years. Currently photoelectric conversion rate is the highest CIGS thin film solar cell, up to 20%, but with more than 30% of the theoretical value is still far away, the main problem is the material indium, gallium distribution and proportion of value is difficult to achieve the desired .
Although thin-film battery technology are higher, but in the mobile Internet era, this is still an industry full of opportunities. In China, China's largest export amount up to modern home textile manufacturer, and now Vosges shares but has thin film solar module production, R & D and production of crystalline silicon solar cell module which two photovoltaic business. Allegedly, its wholly owned subsidiary Vosges Photovoltaic Technology Co., Ltd. is currently working with the German Bosch company to discuss the next step of cooperation, which includes the transfer of shares and other programs. Vosges PV manufacturing a copper indium selenide thin film solar module, is a second-generation photovoltaic technologies highest photoelectric conversion efficiency thin film solar cell, the absorption coefficient of visible light and the photoelectric conversion efficiency of all thin-film solar cell material relatively high.
In the United States, the U.S. solar companies are also rich in Indiana building a large thin film solar module manufacturer, scale, or the nation's largest.
Of solar energy applications, the efficiency and clean doubt, a thin film solar cells to achieve efficient use of mobile devices for expansion, will play a very significant role.
Piezoelectric materials are subject to pressure when a voltage between the end faces of the crystal material. The piezoelectric effect of the principle that, if the pressure of the piezoelectric material, which will produce a potential difference, called positive piezoelectric effect; contrast voltage is applied, the resulting mechanical stress, is called the inverse piezoelectric effect. In recent decades the use of piezoelectric material and gradually expand the scope of, and now find that it is the most practical value of the new human energy. Using piezoelectric materials do wind turbines and wind turbine blades fans, new energy and air used in combination, did not affect the function of wind turbines and electric fans and efficiency, but also the implementation does not consume any extra energy to obtain a practical value of the power to the wind turbine to improve efficiency, so that fans can become a generator, make the air of new energy efficiency exponentially.
Piezoelectric materials are currently the best new energy materials, the use of piezoelectric material with air new energy mix, this new energy structure of output energy to meet the energy needs of humanity, if this new structure to get full use of energy, will be able to further reduce greenhouse gas emissions and slow down global warming, speed, direction of development of the human environment towards benign.
Wireless charging technology
Wireless charging technology the most important is two things, one is the sender on the socket, the other is a receiver on electronic products, as long as a certain range, the power can be transmitted instantaneously to achieve effective.
September 1, 2010, the world's first wireless charging technology to promote standardization organizations - Wireless Power Consortium announced in Beijing Qi wireless charging will be the first to introduce China to international standards. Ministry of Information Industry Communications Electromagnetic Compatibility Quality Supervision and Inspection Center also joined the organization. LG Electronics has launched its first wireless charger WCP-700.
Wireless charging technology uses a unified industry standard for mobile phones, PMP/MP3, digital cameras, laptop computers and other products can use the new low-power, high-compliant same wireless charger. This charger is similar to a tray directly into the power supply, the league certified with "Qi" logo of corporate handsets of different brands can be completed directly on the above charge. For different electronic products, power interface can automatically correspond to needs charging, the transmitter and receiver chips will also start working automatically, when fully charged, the two sides will automatically shut down. It also automatically recognize the type of equipment and energy requirements for 'individual work', which is the smart.
March 30, mobile platforms and semiconductors, enterprise ST-Ericsson has introduced a power management solutions, greatly reducing mobile devices with respect to the wall outlet charging time. This innovation is one of its PowerHUBTM product, the product can capture many sources of energy, not only is the user faster charging, but also can effectively reduce greenhouse gas emissions.
Now, to consumer safety and convenience, wireless charging technology officer at close range wireless charging technology development, but also for remote charging begins further study. Once you have implemented this technology, not just low-power mobile devices, even household appliances, medical equipment, office equipment and so can achieve wireless charging, charging may be side by side without batteries,
With the accelerated pace of modern life, mobile device applications become increasingly widespread. Develop as many mobile power equipment providers must deal with one of the problems. Mobile power achieved effectively improve endurance who can market in this sunrise considerable increase profits.
Meanwhile, the mobile power is a technology with people's lives, so that people can achieve anywhere achieve the same as at home in the office full use of electronic equipment to facilitate people's work entertainment.
