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:What is sun cells technology?
Sun cell technology is a advanced high power generation technology based on how the sun works on our daily life. It utilizses sun power to generate different powers in the technical way (mostly by using silicon as a transimmiter) to generate energy, and use it in our daily work and life.
Q:Why are the poly Solar cell specifications is different from each other, they seem to have the different size of 125mm, 156mm, 152mm, is the 152mm's battery technology is higher than the other?
To make is simple first, the numbers you saw such as 125mm, 156mm, 152mm, refers to the diameter of the silicon wafer.
Q:I studied very hard at school, but I just can not figure out how solar cells work, anybody can help me with that?
It's not a easy job.
Q:How about the current market price for the film solar?
The a-Si ( Amorphous Silicon) thin film solar cells, with the advantage of short energy recovery period, simple manufacture process, inexpensive cost, good performance at high temperature and deposition on the flexible substrate, have been commercially produced and used in daily life.
Q:What kind of products can be considered as the solar cell products?
I think there is nobody else but me could be as qualified to answer this question because 80% of my daily life is surrounded by solar cell product including solar cell shower room, solar cell equipt kitchen, solar cell control lights in all my rooms in the house.
Q:Is the polymer solar cell the cheapest type among all the different kinds of solar cells?
Compared to the other solar cell made of the expensive silicon, polymer solar cells are cheaper.
Q:What is the current situation and the recent progress space solar cells in China?
Because the power supply system is one of the important subsystems of the satellites, they need to be configured with a suitable, reliable power subsystem. The proportion of the power subsystem in the whole satellite system is the highest, so the research on the power supply system is very important.
Q:How can I buy the solar cells wholesale ?
Please feel free to contact us, a solar cell production company based in Zhuhai, Guangzhou Province. We can offer you the best wholesale price with very good quality.
Q:Where can I buy solar cells?
Actually you can rent one, no need to buy one.
Q:What can be used as the materials for solar cells?
EVA.
