Solar cells are electronic semiconductor components, by means of which sunlight can be converted into electric energy. The semiconductor body can consist, for instance, of silicon or a III-V compound such as gallium arsenide and is provided on its front side facing the radiation source with a p-n junction of large area by means of diffusion.

 A method for manufacturing solar cells comprising growing semiconductor whiskers on a substrate, comprising:

(a) Providing a substrate which favors growth or germination of whiskers;

(b) Depositing a plurality of localized areas of an agent in which the semiconductor material is soluble;

(c) Growing whiskers of said semiconductor material by means of the Vapor Liquid Solid (VLS) method at said areas;

(d) Doping the whiskers with one of a p or n doping material; and

(e) Subsequently thereto doping the surface region of said whiskers up to a depth which approximately corresponds to the diffusion length of the charge carriers pairs with the other of a P or n doping material.

Estimating the manufacturing cost of purely organic solar cells

we estimate the manufacturing cost of purely organic solar cells. We find a very large range since the technology is still very young. We estimate that the manufacturing cost for purely organic solar cells will range between $50 and $140/m2. Under the assumption of 5% efficiency, this leads to a module cost of between $1.00 and $2.83/Wp. Under the assumption of a 5-year lifetime, this leads to a levelized cost of electricity (LEC) of between 49¢ and 85¢/kWh. In order to achieve a more competitive COE of about 7¢/kWh, we would need to increase efficiency to 15% and lifetime to between 15–20 years.

Manufacturing Solar Cells

First, silicon raw material is melted and re-cast to remove impurities. The cast silicon is then stabilized in its multicrystalline form. These castings, called "ingots," are then cut into blocks. Next, the ingots are sliced into wafers.( Depending on the type of silicon used, p-type or n-type silicon wafers may be produced). After layering the p-type or n-type wafers, the material is capable of generating electricity from sunlight. Electrodes are attached to the wafers to conduct the flow of electricity. This is called a photovoltaic cell, or "solar cell."

Q:My son is very interested in solar cells recently, and keeps asking me about the structure of a solar cell. Can anybody help me answer that question?
This is what I search online from Wikipedia, solar cell is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect.
Q:What diode does the solar panel use?
It is necessary to allow the light after the effect of electricity into the battery and must prevent the operation of the PV components due to partial damage.
Q:How to define the poly solar cells as the A Grade one?
You can try to define it through the three factors: Efficiency, stability and durability.
Q:What do the solar cell suppliers provide once we purchase the order from the solar cells from them.
The good solar cells suppliers do not only sell you the solar cells products, they also give you very useful suggestions to help you install it.
Q:Can anybody tell me the power supply of the home solar cell?
In my old place, all I was using was the 50WAT solar cells, which is definitely good and useful for all my daily use.
Q:We are currently promoting our one of our solar cells seriers, which is the 156mmx156mm 6inch,2BB/3BB polycrystalline/multi solar cells,mono solar cell,made in Taiwan/Germany, please feel free to contact me if any interest.
Sounds interesting, how about the price and order requirements for this kind of solar cell?
Q:How's the feedback of using 260 watt photovoltaic solar panel? Anybody ever used that?
the 260 watt photovoltaic solar panel is widely used in the solar cell power supply plant, and my personal feedback is very positive.
Q:Is silicon-based solar cells and silicon-based thin-film solar cells the same?
General silicon-based solar cells refer to monocrystalline silicon and polycrystalline silicon solar cells, while silicon-based thin-film solar cells are similar to sunpower producing that type of battery that can be made into curved components.
Q:Monocrystalline silicon and polycrystalline silicon cell in the appearance of what is the difference?
From the appearance point of view: monocrystalline silicon cell four corners were arc-shaped, no surface pattern; polysilicon cell four corners for the square angle, the surface has a similar pattern of ice flowers.
Q:On the parallel connection of solar cells
As for the solar cells in the string, parallel combination is Causing the damage of the battery pack, I think it is first necessary to make sure that the "combined" solar cells should have the same characteristics, and that the various parameters between them should be the same or similar, at least several major parameters must be the same, to achieve these Conditions can be combined after the combination; if the series combination in the use of a group of solar cells damaged and broken, then the other groups will not power the power supply equipment, because the entire line has been in the open state,
