Product Description:

1. Structure of Monocrystalline Silicon Solar Wafer 125*125mm Description

A wafer, also called a slice or substrate, is a thin slice of semiconductor material, such as a crystalline silicon, used in electronics for the

 fabrication of integrated circuits and in photovoltaics for conventional, wafer-based solar cells. The wafer serves as the substrate for

 microelectronic devices built in and over the wafer and undergoes many microfabrication process steps such as doping or ion implantation,

etching, deposition of various materials, and photolithographic patterning. Finally the individual microcircuits are separated (dicing) and

packaged.

Q:Solar panels single crystal and double crystal in the rain which is easy to use
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 main material for making solar panels?
The correct name of solar panels is solar photovoltaic panels, making its main material is monocrystalline silicon or polysilicon silicon, monocrystalline silicon silicon chip more crystalline silicon wafer photoelectric conversion rate is high, the price is also more expensive silicon wafer.
Q:What is the principle of solar panels to convert solar energy into electricity?
Silicon" is one of the most abundant materials on our planet, and since the nineteenth century scientists have discovered the semiconducting properties of crystalline silicon, it almost changed everything and even human thought. At the end of the 20th century, our lives were everywhere Crystal production and process can be divided into five steps: a, purification process b, drawing process c, slicing process d, the system of silicon Battery process e, packaging process.
Q:Single crystal solar panels and polycrystalline solar panels
Monocrystalline silicon solar cells are mainly made of monocrystalline silicon, compared with other types of solar cells, monocrystalline silicon cell conversion efficiency of the highest. In the early days, monocrystalline silicon solar cells occupied most of the market share, in 1998 after the retreat of polysilicon, the market share accounted for second. Due to the shortage of polysilicon raw materials in recent years, after 2004,
Q:Can solar panels be connected directly to motor?
Power supply must be a number of individual battery strings, connected in parallel and tightly packaged into components.
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:Polycrystalline solar panels are good or single crystal solar energy is good
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% (
Q:The voltage and power problems of solar panels
From morning to night (with sunshine) solar panel voltage is generally relatively stable, that is basically about 30V; but the output power is always changing, sooner or later, noon; if it is good quality solar energy,
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:What is the principle of solar panels work?
light - heat - electric conversion method through the use of solar radiation generated by thermal energy, usually by the solar collector will absorb the heat into the refrigerant refrigerant, and then drive the turbine power generation. The previous process is the light-heat conversion process; the latter process is the thermo-electrical conversion process.
