Specifications

AL8866 is a series of aluminum pastes developed for use as the back electrode on single or polycrystalline silicon solar cells.

Technical Data Sheet

Product description

AL8866 is a series of aluminum pastes developed for use as the back electrode on single or polycrystalline silicon solar cells. This low bow aluminum paste is specially designed to form p+ doped layer when fired on a p-doped silicon (<200 microns) photovoltaic devices. This paste has been optimized to eliminate Al bead formation during the firing process.

Q:What are the 3 things you need to know before you start to make solar cells?
I remembered I made solar cells with my dad when I was 10 years old, and all I can remember now are the difficulties in getting the silicon working properly.
Q:How long does it take to make a solar cell?
It is now mass produced, so it doesn't take long to make it in the factory.
Q:How about the solar cell 156mm Mono-Crystalline?
The detailed measurement of the mono solar cell is Format: 156mm*156mm±0.5mm and Thickness: 200μm±20μm
Q:What is the solar cells market in China?
As far as I know, it's developing very well. Not only in terms of the technology but also in terms of the sales revenues. Many solar cells factories are located there
Q:What kind of products can be considered as the solar cell products?
Solar cell product, as simple as it is, is the products which is made of solar cell, or generated by the power converting from solar cells.
Q:Is solar cell technology very developed and v applied to life a lot?
Solar cells are also used in some remote areas, where it's very difficult to use the other energy sources.
Q:Where can I buy solar cells?
Never bought anything like that.
Q:Can somebody list some of the materials used for making solar cells?
Silicon is one of the most important and expensive materials to make solar cells.
Q:Why and what is the low efficiency solar cell?
Sometimes the solar cells made of bad quality silicon can cause the result that the solar cells you are using is lower efficient than when you started to use it. You might need to change some materials.
Q:I am working on research for the usage of solar cells, where can I find more news of solar cells?
Solar daily is the website I used most when I need to get some news about the solar cells.
