Introduce Two Kinds of High Voltage Solar Battery

The three common types of High Voltage solar batteries are multi-component compound film High Voltage solar batteries, polymer multilayer modified electrode type High Voltage solar batteries, and nanocrystalline chemical High Voltage solar batteries. To enhance everyone's understanding of High Voltage solar batteries, this article will introduce two types of High Voltage solar batteries: polymer multilayer modified electrode type LFP energy storage, and nanocrystalline chemical High Voltage solar batteries.

Polymer multilayer modified electrode type High Voltage solar battery

Replacing inorganic materials with polymers in High Voltage solar batteries is a new research direction of solar battery 48v 200ah manufacturing. The principle is to use different redox potentials of different redox polymers to perform multi-layer composites on the surface of conductive materials (electrodes) to make a one-way conductive device similar to an inorganic P-N junction. The inner layer of one of the electrodes is modified by a polymer with a lower reduction potential, the outer polymer has a higher reduction potential, and the direction of electron transfer can only be transferred from the inner layer to the outer layer; the modification of the other electrode is just the opposite, and the first the reduction potentials of the two polymers on each electrode are higher than those of the latter two polymers. When two modified electrodes are placed in an electrolytic wave containing a photosensitizer. The electrons generated by the photosensitizer after absorbing light are transferred to the electrode with a lower reduction potential, and the electrons accumulated on the electrode with a lower reduction potential cannot be transferred to the outer polymer, but can only return to the electrolysis through the external circuit through the electrode with a higher reduction potential. Liquid, so there is a photocurrent generated in the external circuit.

Due to the advantages of good flexibility, easy fabrication, a wide range of material sources, and low cost, organic materials are of great significance to the large-scale utilization of solar energy and the provision of cheap electricity. However, the research on the preparation of 51.2V 10kWh lifepo4 batteries with organic materials has only just begun, and neither the service life nor the battery efficiency can compare with inorganic materials, especially silicon batteries. Whether it can be developed into a product with practical significance remains to be further researched and explored.

Nanocrystalline chemistry High Voltage solar battery

Among the High Voltage solar batteries, the silicon-based High Voltage Lithium Battery is undoubtedly the most mature, but due to the high cost, it is far from meeting the requirements for large-scale promotion and application. For this reason, people have been constantly exploring terms of technology, new materials, and battery thinning. Among them, the recently developed nano-TIO2 crystal chemical energy High Voltage solar battery has attracted the attention of scientists at home and abroad. Since Professor Gratzel of Switzerland successfully developed the nanometer TIO2 chemical large solar cell, some domestic units are also conducting research in this area. A nanocrystalline chemical battery backup solar (referred to as NPC battery) is formed by modifying and assembling a semiconductor material in a bandgap to another semiconductor material with a large energy gap. The narrow bandgap semiconductor material uses transition metals such as Ru and Os. The organic compound sensitizing dye, the large energy gap semiconductor material is nano-polycrystalline TIO2 and is made into an electrode. In addition, the NPC battery also selects an appropriate oxidation-reduction electrolyte. The working principle of nanocrystalline TIO2: the dye molecule absorbs sunlight energy and jumps to the excited state, the excited state is unstable, electrons are quickly injected into the adjacent TiO2 conduction band, and the electrons lost in the dye are quickly compensated from the electrolyte and enter the TiO2 conduction band The electricity in the film finally enters the conductive film, and then generates photocurrent through the outer circuit.

The advantages of nanocrystalline TiO2 High Voltage solar battery lie in their low cost, simple process, and stable performance. Its photoelectric efficiency is stable above 10%, and the production cost is only 1/5-1/10 of that of silicon solar cells. The service life can reach more than 20 years.
