Product Description

Product Description

What are N-type solar ?

An N-type solar cell consists of a thin p-type silicon (doped with boron) layer over a much thicker n-type silicon (doped with phosphorus) layer. Electrical contacts are applied to both sides. The p-side is the front side facing the sun. It is given an antireflective coating, over which is pasted a clear adhesive (for instance EVA) which holds the front protective glass layer.
Currently most of the crystalline solar cells are p-type. This is because of a lower cost of production of p-type. The reasons are probably attributable to history of development of solar cells. But performance wise, n-type solar cells can give much better efficiency compared to p-type solar cells. Two main factors account for this. Firstly, p-type material has boron (trivalent) doping. In the presence of light and oxygen boron undergoes some undesirable action, which reduces efficiency of conversion. This is called Light Induced Degradation or LID.

FAQ

1. Are you a factory or trade company?
A: As a professional manufacturer, our company was established in 2012. Our company has been engaged in manufacturing Lithium lon Phosphate battery power system, and trading in photovoltaic solar panel, inverter, heat pumps for many years.

2. How could I buy the solar panel if there is no price in the website?
A: We have some products in stock and in promotion. Prices of these products are much cheaper than normal. You can send your inquiry to us about the solar panel you need, our sales person will reply you within 24 hours to help you make the order.

3. Do you accept ODM/OEM orders?
A: Yes. we can accept OEM/ODM. We can talor the logo and functions as per your requirement

4. How can I make sure it's a secure transaction ?
A: Alibaba can protect buyers' interest, all of our transation will go through alibaba platform. As you do the payment, the money will go directly to Alibaba bank account. After we ship to you the goods and you comfirm the detailed information, Alibaba will release us the money.

5. How do you pack the solar panels?
A: We use standard strong quality cartons. lf you have special package requirements.we will pack based on your requirements.

6. When we install the solar projects, can we step on the panels?
A: Please don't step on the panels when installing the panels and handle with care when moving the panels. This can help avoid cracks inside the panels. You can't see the cracks by your eyes, but it will effect the life of solar panel.

7. Do your company also provide other solar productsexcept standard solar panels?
A: We also can supply solar system, residential energy storage battery, solar inverter, solar controller, portable power station and so on.
