The development of mobile Internet requires the support of mobile power. In this field, there are mainly thin film battery technology, piezoelectric material technology and wireless charging technology.
In the era of mobile Internet, a very important part of the use of the client is its use time. No matter how excellent the performance, the mobile phone, tablet or other smart products that cannot be opened when disconnected from the wired power supply cannot be effectively applied.
In the need to improve the battery life, one can reduce the amount of power used at the same time, such as the iPad, saving all the power-saving ways that can be saved, saving all the space that can be saved, but for the rapid development of IT products In fact, it is not suitable. Another method is to improve the performance of the battery, and provide more sustainable endurance for the product. The development of the mobile Internet requires the support of mobile power. In this field, there are mainly thin film battery technology, piezoelectric material technology, and wireless charging technology.
Thin film battery
The most ideal source of energy that can be accessed anytime, anywhere is solar energy. The application of solar energy is a problem that humans have been striving for in history. Although monocrystalline silicon solar cells dominate the large-scale application and industrial production at this stage, they also expose many shortcomings, the most important of which is the high cost. At the same time, affected by the price of single crystal silicon material and the preparation process of single crystal silicon battery, it is very difficult to greatly reduce the cost of single crystal silicon solar cells.
Thus, it has produced alternative thin film solar cells, including amorphous silicon thin film solar cells, selenium indium copper and cadmium telluride thin film batteries, and polycrystalline silicon thin film solar cells. The most important advantages of amorphous silicon thin film solar cells are low cost and easy preparation. Since their photoelectric conversion efficiency will decay with the continuation of illumination time, its instability is also obvious.
As for the selenium indium copper and cadmium telluride polycrystalline silicon thin film batteries, the efficiency is higher than that of the amorphous silicon thin film battery, the cost is lower than that of the single crystal silicon battery, and the mass production is easy, and there is no problem of sharp drop in efficiency, which seems to be one of the amorphous silicon thin film batteries. A good alternative. Only a large amount of pollution generated in the production process of polycrystalline silicon thin film batteries can not be ignored. The raw materials such as selenium, indium and antimony are rare metals, and the space for further reducing the cost is small.
Because the amount of silicon used is much smaller than that of single crystal silicon, and the inefficiency is reduced, the polycrystalline silicon thin film battery is expected to be prepared on an inexpensive substrate. The cost is expected to be much lower than that of a monocrystalline silicon battery, and the laboratory efficiency has reached 18%, much higher than the efficiency of amorphous silicon thin film batteries. Therefore, polycrystalline silicon thin film batteries are considered to be the next generation of solar cells most likely to replace monocrystalline silicon cells and amorphous silicon thin film cells, and have now become a research hotspot in the international solar energy field.
Solar thin film batteries have lower production costs and their market share has continued to increase in recent years. At present, the highest photoelectric conversion rate is copper indium gallium selenide solar thin film battery, up to 20%, but still far from the theoretical value of more than 30%, the main problem is that the distribution of indium and gallium in the material is difficult to reach the ideal value. .
