Product Description:

Solar Cell Characteristics

• High efficiency and stable performance in photovoltaic conversion.
• Advanced diffusion technique ensuring the homogeneity of energy conversion efficiency of the cell.
• Advanced PECVD film forming, providing a dark blue silicon nitride anti-reflection film of homogenous color and attractive
appearance.
• High quality metal paste for back surface and electrode, ensuring good conductivity, high pulling strength and ease of soldering.
• High precision patterning using screen printing, ensuring accurate busbar location for ease with automatic soldering a laser cutting.

THE CHARACTERISTIC OF 156P POLY-SILICON SOLAR CELLS

1.Format 156mm×156mm±0.5mm,Thickness 210μm±30μm.
2.High efficiency in photovoltaic conversion 16.3%~17.93%;
3.Low inverse current, high shunt resistance and high dependability.
4.Front(-): covered by dark blue silicon nitride anti-reflecting coating(silicon nitride) with bus bars(silver), 2/3/5 bud bars(silver).
5.Back(+): wide soldering pads(silver), back surface field(aluminum),high quality paste for the BSF and the electrode ensure higher tension and improve soldering easiness.

Q:The working principle of solar cells includes the three processes: The solar cells absorb photons with a certain energy and excite unbalanced carriers (photogenerated carriers) - electron - hole pairs. These electrons and holes should have sufficient life, and they will not disappear after they are separated.

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:How about the current market price for the film solar?: Just for your reference, we are a film solar supplier based in US, and the price for the film solar is around USD 20 each.

Q:What are the short-circuit currents of solar cells affected by the factors?: The size of the suede, the uniformity, the depth of diffusion, the film thickness of the PECVD, the printing condition of the screen and the sintering conditions,

Q:How long does it take to make a solar cell?: If you decide to make it by yourself, it will take you very long.

Q:Is it possible to learn how to make solar cells by yourself?: I did that when I was 15 years old, and I succeeded!

Q:Doping and Diffusion Principle in Solar Cell Processing: In some inorganic solid compounds doped with different metal ions, can be different properties of luminescent materials, such as yttrium oxide (III) doped with europium (III) ions can be red fluorescent materials.

Q:What is the solar cell?: When the surface of the solar cell and the electrode on the back side are connected with each other, a current flows.

Q:What is the most commonly used material for solar cells?: Anyone of these is the materials for making the solar cells: Crystalline silicon solar cell, silicon solar cell, silicon solar cell. Amorphous silicon cell: thin film solar cells, organic solar cells. Chemical dye cell plate: dye sensitized solar cell.

Q:What is sun cells technology?: The sun cell is a device that convert light energy into electric energy by a using photovoltaic effect. It is also called photovoltaic device.
