Photovoltaic glass is a special type of glass that converts sunlight into electricity by encapsulating solar cell modules in layers of glass. Usually low-iron tempered glass or double-layer glass is used, and the surface is coated with anti-reflection coating and transparent conductive layer.
Float glass is a common glass manufacturing process. In the production process, glass raw materials (such as silica sand, sodium carbonate, limestone, etc.) are melted, flowed out evenly from the top of the glass melting bath, and solidified into thin flake glass after cooling. This technique produces high-quality, uniform-thickness glass for a wide variety of applications.
The difference between photovoltaic glass and float glass is mainly reflected in the following aspects:
Different uses: Photovoltaic glass is mainly used in the manufacture of solar panels, while float glass is widely used in construction, automobiles and other fields;
Different materials: Photovoltaic glass usually uses special materials such as low-iron tempered glass or double-layer glass, while float glass is produced by using ordinary glass raw materials through special processes;
The manufacturing method is different: photovoltaic glass needs to be coated with anti-reflection coating and transparent conductive layer on the surface, and the solar cell module is encapsulated in it. Float glass, on the other hand, is made from thin sheets of glass by melting the raw material.
Different performance requirements: Photovoltaic glass needs to have certain special properties such as transmittance, reflectivity and wind pressure resistance, while float glass mainly requires uniform thickness, high strength and light transmission performance.

Considering factors such as conversion efficiency of solar panels, technical level, maturity of production process, market share, etc., for large-scale grid-connected photovoltaic power plants, the types of solar panels currently commonly used can be roughly divided into crystalline silicon solar panels and amorphous silicon solar panels. Crystalline silicon solar panels are further divided into monocrystalline silicon solar panels and polycrystalline silicon solar panels. Amorphous silicon solar panels are mainly thin-film solar panels. The following is a brief analysis of the conversion efficiency of various photovoltaic solar panels:
1. Monocrystalline silicon solar panels Monocrystalline solar panels are the most common high-efficiency solar panels on the market today. The production process and technological breakthroughs of the single crystal industry chain determine that it has a more perfect crystal lattice, can better absorb light, and has a higher conversion efficiency. For monocrystalline solar panels, the efficiency of PERC high-efficiency monocrystalline solar cells has exceeded 23%, setting a world record. The conversion efficiency of ordinary monocrystalline solar cells is also above 19%, which is the highest photoelectric conversion efficiency among all types of solar cells. With the continuous maturity of technology, the price of monocrystalline solar panels is almost the same as that of polycrystalline. Because monocrystalline silicon is generally encapsulated with tempered glass and waterproof resin, it is durable and its service life can generally reach 20 years, and the maximum can reach 30 years.
2. Polycrystalline silicon solar panels Compared with monocrystalline solar cells, the silicon wafer of polycrystalline solar cells is a combination of multiple tiny single crystals, with a large number of grain boundaries in the middle, including many defects. It is actually a minority carrier recombination center, thus reducing the polycrystalline silicon. At present, the conversion efficiency of polycrystalline solar cells is about 18%-20%.
3. Thin film solar panels After several years of rapid development, the laboratory efficiency of single-junction amorphous silicon thin-film solar cells can reach about 12.7%, and the laboratory efficiency of microcrystalline silicon multi-junction solar cells can reach 13.4%. The laboratory photoelectric conversion efficiency of solar cells can reach 16%, and the average efficiency of commercial solar cells is 8%-10%. The conversion efficiency of copper indium gallium selenide can reach 14%.
However, compared with crystalline silicon solar panels, the main problem of thin-film solar panels is the low photoelectric conversion efficiency, and the area of thin-film solar panels required to convert the same amount of electric energy is huge. In addition, thin-film solar panels also have the disadvantage of poor stability, and their energy conversion efficiency changes with the prolongation of irradiation time. These shortcomings are the biggest obstacles to the wide application of thin-film solar panels. From the analysis of the conversion efficiency of the above three types of photovoltaic solar panels, it is not difficult to see that the conversion efficiency of crystalline silicon solar panels is significantly higher and more stable than that of thin-film solar panels. Monocrystalline silicon solar panels have significantly higher conversion efficiency and are more stable than polycrystalline silicon solar panels. For the selection of photovoltaic power plant components, it should be combined with the specific conditions of the project, and the corresponding technical and economic comparison analysis should be carried out to finally determine the best solar panel selection suitable for the photovoltaic power plant.
