Q:Single crystal solar panels and polycrystalline solar panels
Monocrystalline silicon cells in the laboratory to achieve the conversion efficiency of 24.7%. Ordinary commercial conversion efficiency of 10% -18%. Monocrystalline silicon solar cells because of the production process problems, generally its semi-silicon ingots for the cylindrical into, and then through the slice -> cleaning -> diffusion knot -> remove the dice -> the production of electrodes -> corrosion around -> Reflective film and other workers made of finished products. General monocrystalline silicon solar cells four corners for the fillet. Monocrystalline silicon solar cell thickness is generally 200uM-350uM thick, and now the production trend is to ultra-thin and efficient direction
Q:What is the difference between solar panels and light panels?
The highest conversion efficiency in the laboratory is 24.7%, and the efficiency of the scale is 16%. Polysilicon conversion rate of 14% -15%. Amorphous silicon conversion rate of 12%. Silicon film conversion rate of 9%. Silicon solar cell is the main raw material of silicon, silicon is an extremely rich element of the earth, almost everywhere there are silicon, can be said to be inexhaustible, with silicon to create solar cells, raw materials can be described as no shortage.
Q:Polycrystalline solar panels are good or single crystal solar energy is good
From the cost of production, than the monocrystalline silicon solar cells to be cheaper, easy to manufacture materials, saving power consumption, the total cost of production is low, so get a lot of development. In addition, the polysilicon solar cell life than monocrystalline silicon solar cells shorter. From the performance and price ratio, monocrystalline silicon solar cells also slightly better.
Q:What is the principle and structure of solar panels?
solar panels: solar panels is the core of solar power generation system, solar power system is the highest value of the part. Its role is to convert the sun's radiation capacity into electricity, or sent to the battery to store, or to promote the load work.
Q:How many solar panels have ah?
The area of ​​the solar cell chip is not exactly the same as the area of ​​the solar package panel, because some solar panels, although large, single solar wafer arrangement gap is wide, so that the solar panel power is not necessarily high. 2, in general, the power of solar panels is the bigger the better, so that the current generated in the sun, and soon it will be filled with built-in battery.
Q:Why can not the solar panel load directly?
Solar panels because of low power, and the output voltage is extremely unstable, not suitable for load.
Q:What is the working principle of solar panels?
The production of solar cells is mainly based on semiconductor materials, its working principle is the use of optoelectronic materials to absorb light energy after the photoelectricity in the conversion reaction, according to the different materials used, solar cells can be divided into:
Q:Composition and function of solar panels
Among them, for the electronic grade polysilicon accounted for about 55%, solar grade polysilicon accounted for 45%, with the rapid development of photovoltaic industry, solar cell demand for polysilicon growth rate higher than the development of semiconductor polysilicon, is expected to 2008 solar polysilicon
Q:Solar panels single crystal and double crystal in the rain which is easy to use
Polycrystalline silicon solar cell production process and monocrystalline silicon solar cell almost, but the polysilicon solar cell photoelectric conversion efficiency will have to reduce a lot of its photoelectric conversion efficiency of about 12% (July 1, 2004 Japan Sharp market efficiency of 14.8% Of the world 's most efficient polysilicon solar cells).
Q:Can solar panels be connected directly to motor?
The sun is irradiated on the semiconductor p-n junction to form a new hole-electron pair. Under the action of the p-n junction electric field, the holes flow from the n region to the p region. The electrons flow from the p region to the n region, and the current is formed after the circuit is turned on.
