Silicon solar

Silicon High Voltage solar battery is divided into three types: monocrystalline silicon High Voltage solar battery, polycrystalline silicon thin film High Voltage solar battery, and amorphous silicon thin film High Voltage solar battery.

Monocrystalline silicon solar charger batteryhas the highest conversion efficiency and the most mature technology. The highest conversion efficiency in the laboratory is 24.7%, and the efficiency in large-scale production is 15% (as of 2011, it is 18%). It still occupies a dominant position in large-scale applications and industrial production, but due to the high cost of monocrystalline silicon, it is difficult to greatly reduce its cost. To save silicon materials, polycrystalline silicon thin films, and amorphous silicon thin films have been developed as monocrystalline silicon High Voltage An alternative to solar batteries.

Polycrystalline silicon thin film High Voltage solar battery is cheaper than monocrystalline silicon, and its efficiency is higher than that of amorphous silicon thin film battery. The highest conversion efficiency in the laboratory is 18%, and the conversion efficiency in industrial-scale production is 10% (as of 2011, it was 17% %). Therefore, polysilicon thin film batteries will soon occupy a dominant position in the solar battery 48v 200ah market.

Amorphous silicon thin film High Voltage solar battery is low in cost, light in weight, high in conversion efficiency, convenient for mass production, and has great potential. However, due to the degradation effect of photoelectric efficiency caused by its material, its stability is not high, which directly affects its practical application. If the stability problem and the conversion rate problem can be further solved, then the amorphous silicon High Voltage solar battery is undoubtedly one of the main development products of the High Voltage Lithium Battery.

Polycrystalline film

Polycrystalline thin-film batteries Cadmium sulfide and cadmium telluride polycrystalline thin-film batteries have higher efficiency than amorphous silicon thin-film 51.2V 10kWh lifepo4 batteries, lower cost than monocrystalline silicon batteries, and are easy to mass-produce, but because cadmium is highly toxic, It will cause serious pollution to the environment, therefore, it is not the most ideal substitute for crystalline silicon 51.2v lifepo4 battery.

The conversion efficiency of gallium arsenide (GaAs) III-V compound battery can reach 28%. The GaAs compound material has a very ideal optical band gap and high absorption efficiency. It has strong radiation resistance and is not sensitive to heat. It is suitable for manufacturing High-efficiency single-junction batteries. However, the high price of GaAs materials limits the popularity of GaAs batteries to a large extent. Copper indium selenium thin film battery (referred to as CIS) is suitable for photoelectric conversion, there is no problem with light-induced degradation, and the conversion efficiency is the same as that of polysilicon. It has the advantages of low price, good performance, and simple process, and will become an important direction for the development of High Voltage solar batteries in the future. The only problem is the source of materials. Since indium and selenium are relatively rare elements, the development of this type of battery must be limited.

Organic polymer

Replacing inorganic materials with organic polymers is a research direction in the manufacture of High Voltage solar batteries that has just begun. Due to the advantages of good flexibility, easy fabrication, wide material sources, and low cost, organic materials are of great significance for the large-scale utilization of solar energy and the provision of cheap electricity. However, the research on the preparation of solar storage 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

Nano TiO2 crystal chemical energy High Voltage solar battery is newly developed, and its advantages lie in its cheap cost, simple process, and stable performance. Its photoelectric efficiency is stable above 10%, and its production cost is only 1/5-1/10 of that of silicon solar cells. The life span can reach more than 20 years. The research and development of this type of battery have just started, and it will gradually enter the market shortly.

Organic film

An organic thin film High Voltage solar battery is a battery backup solar whose core part is composed of organic materials. Everyone is not familiar with organic High Voltage solar batteries, which is reasonable. In today's mass-produced High Voltage solar batteries, more than 95% are silicon-based, and the remaining less than 5% are also made of other inorganic materials.

Dye sensitization

Dye-sensitized lithium battery is to attach a pigment to TiO2 particles and then soaks them in an electrolyte. When the pigment is irradiated with light, free electrons and holes are generated. The free electrons are absorbed by TiO2, flow out from the electrode and enter the external circuit, then pass through the electrical appliance, flow into the electrolyte, and finally return to the pigment. The manufacturing cost of dye-sensitized High Voltage solar batteries is very low, which makes it very competitive. Its energy conversion efficiency is about 12%.
