(1) Silicon solar cells
Silicon solar cells are divided into three types: monocrystalline silicon solar cells, polycrystalline silicon thin film solar cells and thin film solar cells thin amorphous silicon.
(2) Multi-compound thin-film solar cell
The materials of multi-compound thin-film solar cells are inorganic salts, which mainly include arsenide compounds of gallium III-V, cadmium sulfide, cadmium. sulfide and copper-indium-selenium thin film batteries, etc.
(3) Polymer multilayer modified electrode solar cells
Replacing inorganic materials with organic polymers is a research direction in solar cell manufacturing that is just emerging. to start. Due to the advantages of organic materials such as flexibility, ease of production, larges sources of materials and low cost, they are of great importance for the large-scale use of solar energy and the supply of cheap electricity. However, research into using organic materials to prepare solar cells is only just beginning. Neither the lifespan nor the efficiency of the cells can be compared to that of inorganic materials, especially silicon cells. Whether it can become a product of practical importance remains to be studied and explored in more detail.
(4) Nanocrystalline solar cells
Nano-TiO2 crystal chemical solar cells are newly developed, and their advantages lie in low cost, simple process and stable performance. Its photoelectric efficiency is stable at more than 10%, and its production cost is only 1/5 to 1/10 of that of silicon solar cells. The lifespan can reach more than 20 years.
(5) Organic thin-film solar cells
Organic thin-film solar cells are solar cells whose core is composed of organic materials. It makes sense that not everyone is familiar with organic solar cells. More than 95% of solar cells mass-produced today are silicon-based, while the remaining less than 5% are also made of other inorganic materials.
(6) Dye-sensitized solar cells
Dye-sensitized solar cells attach pigment to TiO2 particles, then soak them in an electrolyte. The pigment is exposed to light and generates free electrons and holes. The free electrons are absorbed by TiO2, flow from the electrode to the external circuit, then pass through the electrical device, flow into the electrolyte and finally return to the pigment. The manufacturing cost of sensitized solar cells hasux dyes is very weak, which makes them very competitive. Its energy conversion efficiency is around 12%.
What are solar cells?
Solar batteries are devices that convert solar energy into electrical energy and store it. They constitute an essential element of the solar energy production system. However, there are many types of solar batteries on the market. How to choose the right solar battery?
Consider the energy storage capacity
The energy storage capacity is an important parameter of solar batteries, which determines the energy storage capacity of the system solar energy production. Generally speaking, the larger the energy storage capacity, the more electricity can be stored, but the price will also increase accordingly. Therefore, when selecting solar batteries, the energy storage capacitymust be determined based on actual needs and budget.
Consider the charging and discharging efficiency
Charging and discharging efficiencyEfficiency is another important parameter of the solar battery, which determines the energy loss of the system solar energy production. Generally speaking, the higher the charging and discharging efficiency, the lower the energy loss and the higher the power generation efficiency of the solar power generation system. Therefore, when choosing a solar battery, you should choose a product with higher charging and discharging efficiency.
Consider the lifespan
The lifespan of solar batteries is an important consideration. Generally speaking, the longer the lifespan of a solar battery, the lower the maintenance costs. Therefore, when choosing solar batteries, you should choose products with a long lifespan.and longer life.
Consider environmental adaptability
Solar batteries must be used outdoors, so environmental adaptability is also an important consideration. Generally speaking, solar batteries should be waterproof, dustproof and corrosion-proof to adapt to different environmental conditions. Therefore, when choosing solar batteries, you should choose products with good environmental adaptability.
Operation steps
1. Determine the actual needs and budget of the solar power generation system
2. Select the appropriate solar battery according to actual needs; and the budget;
3. When selecting solar batteries, factors such as energy storage capacity, charging and discharging efficiency, service life and environmental adaptability;
4. Install according to the solar battery seselected and debugging.
Solar cells, also known as photovoltaic cells, are semiconductor devices that convert solar energy into electrical energy. Here are the most common types of solar cells:
Silicon solar cells: Silicon solar cells are the most common type of solar cells and include monocrystalline silicon, polycrystalline silicon, and amorphous silicon. Monocrystalline silicon solar cells have the highest efficiency, but have higher costs; polycrystalline silicon solar cells have lower costs and are slightly less efficient; Amorphous silicon solar cells have low production costs, but have the lowest efficiency.
Cadmium selenide solar cells: Cadmium selenide solar cells have high efficiency and long life, but they containrelease toxic substances.
Copper-indium-gallium selenide solar cells: Copper-indium-gallium selenide solar cells are made of copper, indium, gallium and selenium and have high efficiency, but the cost of production is high.
Organic solar cells: Organic solar cells use organic materials as semiconductors and are relatively inexpensive, but have low efficiency and a short lifespan.
Dye-Sensitized Solar Cells: Dye-sensitized solar cells use organic dyes to absorb solar energy and then convert it into electricity. They have the advantage of being inexpensive, light, flexible and easy to manufacture, but are less effective.
Perovskite solar cell: Perovskite solar cell is a new type of solar cell developed in recent years, which has the advantages of high efficiencyhigh, low cost and long life.
