1. Structure of  Solar Mono Silicon Wafer for Solar Cell (156 and 125)  Description

A wafer, also called a slice or substrate, is a thin slice of semiconductor material, such as acrystalline 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:What's the difference between a silicon wafer and a battery?
Silicon chip, is a large piece of silicon, cut into a filmSolar cell, the mainstream is the silicon wafer made of crystalline silicon solar cells, or other solar cells: thin film solar cells, amorphous silicon solar energy, solar cells and so on
Q:How many watts can a piece of silicon produce
A piece of silicon, has been able to integrate 160 thousand transistors. What a fine project! This is the crystallization of multidisciplinary collaborative efforts, is another milestone in the progress of science and technology.
Q:What is the specific way to clean the silicon wafer suede concrete steps
LED (Light Emitting Diode), light emitting diode, referred to as LED, is a kind of power can be converted into visible light solid-state semiconductor devices, which can directly convert electricity into light. The heart of LED is a semiconductor chip, one end of which is attached to a support, one end is a negative electrode, and the other end is connected with the positive electrode of the power supply so that the whole chip is encapsulated by epoxy resin. The semiconductor chip is made up of two parts, one part is the P type semiconductor, in which the hole is dominant, the other end is the N type semiconductor.
Q:Hydrogen passivation mechanism of hydrogen fluoride HF in silicon wafer RCA cleaning process
When the concentration of NaOH is higher than 20%W/V, the corrosion rate depends mainly on the temperature of the solution, but not on the actual concentration of the alkali solution.Removal of surface oxide layer on silicon wafer by HF:
Q:How to avoid or reduce the fragmentation of thin silicon wafers without wax polishing?
The wax free polishing template can ensure the free rotation of the silicon wafer in the groove of the template,
Q:I grew Ag particles on a silicon wafer, about a few hundred nanometers in size
And then use the copper net fishing, so that particles attached to the copper network.
Q:Why is it not easy to use high resistance on the silicon chip integrated circuit
In some places, the resistance of the epitaxial layer is adopted, and the resistance is N type, which has a lot of inconvenience in the circuit, and the numerical value is also very difficult to do
Q:How to detect the surface finish of photovoltaic silicon wafers, what equipment?
Physical examination of the surface roughness on the line, whether it can be cleaned with chemical or optical
Q:Why do monocrystalline silicon chamfer? Polysilicon film?
Chamfering is for this purpose, grinding and polishing are also for this purpose. As a single crystal practitioners, it is recommended that you take a look at the processing technology of silicon single crystal wafer > this book, written by Zhang Juezong, more comprehensive
Q:What is a semiconductor silicon device tester
First of all the circuit insulator carrier plays a supporting role in the insulation layer of the circuit is called the substrate (like P type semiconductor) to participate in the work of the collection circuit to take the CMOS process Nmos substrate are connected with the substrate
