Monocrystalline silicon battery.lithium battery 12v 100ah

　　Classification of semiconductor batteries

　　The basic material of monocrystalline silicon solar cells is P-type monocrystalline silicon with a purity of 0.999999 and a resistivity of over 10 ohms per centimeter. Including p-n junction, electrode, and anti reflection film. The illuminated surface is protected by a transparent cover (such as quartz or cerium infiltrated glass) to prevent the battery from being damaged by the radiation of high-energy electrons and protons in the Van Allen band of outer space. The size of a single battery varies from 2 × 2 cm to 5.9 cm × 5.9 cm, the output power is tens to hundreds of milliwatts, its theoretical Solar-cell efficiency is 20%, and the actual has reached 11.2%~14.8%.

　　Single crystal gallium arsenide battery

　　The theoretical Solar-cell efficiency of single crystal GaAs solar cells is 24%, and the actual efficiency is 18%. It can work at high temperatures and high light intensity, with higher radiation damage resistance than silicon solar cells, but the production of gallium is relatively small and the cost is high. Cascaded p-n junction solar cell is a p-n junction with multiple different band gap materials superimposed on a substrate. The top junction with large band gap is close to the illumination surface to absorb short wave light. The lower band gap decreases in turn, and the wavelength of the absorbed light wave gradually increases. This kind of cell can make full use of sunlight, and the Solar-cell efficiency is greatly improved. In order to improve the performance of individual solar cells, measures such as shallow junctions, dense grids, back electric fields, back reflectors, textured surfaces, and multilayer films can be taken. Increasing the area of a single cell is beneficial for reducing the welding points of the solar array and improving its reliability.

　　Lithium-ion conductor battery

　　A substance with ionic conductivity. It is a fast ion conductor. It has the characteristics of high conductivity (greater than 102S · cm), low activation energy (less than 0.5eV), and the most negative electrode potential. Li3N with layered structure, Lisicon (Li14ZnGeO4) with skeleton structure and Solid solution based on LiTi2P3O12 have been more studied. However, inorganic lithium ion conductors have no practical value due to different conductivity, low decomposition voltage, and lack of resistance to metal lithium corrosion. Organic lithium ion conductors, such as the complex of polymer (such as polyoxyethylene) and alkali metal salt (such as LiCF3SO3), are found later, although their conductivity is lower than that of inorganic lithium ion conductors, they are easy to be processed into films, which make up for the lack of conductivity, and have good Viscoelasticity. They have been widely used as diaphragm materials for high-energy lithium batteries, and are used to manufacture high specific energy, large capacity batteries and high-temperature fuel cells.
