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:Doping and Diffusion Principle in Solar Cell Processing
The doping of semiconductors mainly relies on the principle of ion diffusion from high concentrations like low concentrations.
Q:How does the photovoltaic cells work?
Photovoltaic cells use the photovoltaic effect to convert sunlight directly into electric current and voltage.
Q:What is a good introduction of solar cell?
You should start with a nice ppt.
Q:How do solar cells work to become the solar energy?
Solar cells are a material used in producing solar energy. There are also many kinds of solar cells based on it's material and usage.
Q:What is a High-efficiency electric solar cell panel?
We should first check if the power output performance are stable, if not, no matter how high the power supply would be, it is not efficient but just unsafe.
Q:How's the feedback of using 260 watt photovoltaic solar panel? Anybody ever used that?
The 260 watt photovoltaic solar panel is very normally used in the market, and the feedback is not bad based on its quality.
Q:How long is the long cycle solar cell life?
There are charging conditions, if often less than filling, charge less than the release, then it will soon be "broken", a single cycle of the amount of charge should be more than 1.2 times the discharge
Q:My solar cells are broken, can I just buy one and replace it?
It's a bit risky to do that by yourself.
Q:What's the benefit of using a solar cell?
It can protect our environment better.
Q:Is the solar cells factory in China good and trustworthy?
We are a foreign company selling the solar cells all over the world, we actually set up our solar cell factory in China 5 years ago, and it turns out to be very good.
