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 do the solar cell suppliers provide once we purchase the order from the solar cells from them.
The good solar cells suppliers do not only sell you the solar cells products, they also give you very useful suggestions to help you install it.
Q:Is A grade better than the B grade when we buy the poly solar cells.
Poly Solar Cells B Grade might not sound very competitive to the purchasing managers who are purchasing the poly solar cells in the market, but that’s what I need.
Q:How to generate solar cells, the principle of PN junction
Solar energy is an inexhaustible renewable energy source for human beings, and it is clean energy and does not produce any environmental pollution. In the effective use of solar energy; solar energy photoelectric utilization is the fastest growing and most dynamic in recent years
Q:Where can I find more information about the work process of solar cells
From wikipedia, where you can find almost everything you need.
Q:What is the difference between polysilicon and monocrystalline silicon photovoltaic cells?
Monocrystalline silicon cells with high battery conversion efficiency, good stability, but the higher cost. Polycrystalline silicon cells are less costly and slightly lower in conversion efficiency than straight-drawn monocrystalline silicon solar cells, with various defects in materials such as grain boundaries, dislocations, microdefections, and impurity carbon and oxygen in materials, as well as tarnished during process Transition metal.
Q:How can I explain to my 10 year old daughter what solar cells are?
I had the same question from my son when he was 11 years old. All I did was I took him to the National Electricity museum, and it explains everything about solar cells.
Q:What should I know about the Crystalline silicon photovoltaic cells?
Crystalline silicon photovoltaic cells work by using crystalline silicon photovoltaic effect and power of the solar cell in generating the electrical power. It is not only used in the daily life but also in the industrail markets.
Q:Can anybody tell me how to make a solar cell at home?
All I can tell you is "yes you can!"
Q:What is the window material in the solar cell? what's the effect?
The general window layer to play with the battery body layer to form the role of electric field within the pn junction, if the battery body layer is N-type, the window is p-type, and vice versa.
Q:Does the solar cell generate electricity in the absence of the sun, only in the case of strong lights or lasers? If you can achieve how much, and the same day?
Sunlight is a composite light, in which only the frequency is greater than the solar cell threshold photons can effectively stimulate the solar cell power generation.
