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 is sun cells technology?
Sun cells use high technology to change the sun's light energy into electrical energy. The sun cells can be used in the industries such as satellites, navigation lights, transistor radios and other power supply services.
Q:Is A grade better than the B grade when we buy the poly solar cells.
The quality of the poly solar cell is differentiated by grade, therefore, A grade is better than B grade.
Q:How can I understand the working principles of solar cells?
All in all, the working principle of a solar cell can be understood in this way, a high technology that use the sun energy for electricity.
Q:How much does a solar cell cost?
I never did the exact calculation, but it does cost much more than I thought.
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.
Q:How about the current market price for the film solar?
The price for the film solar in the Chinese market is changed a lot due to the mass production of the film solar in a lot of factories.
Q:Where can I buy solar cells?
Maybe at the local equipment shop?
Q:How can the solar power change our life by using solar cells material?
Solar power is at least 1/3 less expensive than coal-fired power . How can not the solar energy be used to change our life?
Q:Is that true that the price of solar cells will be reduced in the coming year?
According to the research and survery we did recently in the 2nd tier cities in China, the possibility of the solar cells' price going down is very low. Reasons? All the solar cells project hasn't started yet at the end of the last year in the 2nd tier cities in China. The market won't allow the price to go down.
Q:Is the polymer solar cell the cheapest type among all the different kinds of solar cells?
Yes, the polymer solar cells are the cheaper type.
