Monocrystalline Solar Cells A GRADE 156*156mm
Solar cells is made by solar wafer, it has three categories of solar cell right now, monocrystalline polycrystalline and thin film,These cells are entirely based around the concept of ap-n junction, which is the critical part of solar module, it is the part that can convert the light energy into electricity, the thickness is from 180um to 200um, with even busbars to conduct electricity, textured cell can decrease diffuse reflection; they are often electrically connected and encapsulated as a module. Photovoltaic modules often have a sheet of glass on the front (sun up) side, allowing light to pass while protecting semiconductor wafers from abrasion and impact due to wind-driven debris, rain, hail, etc. Solar cells are also usually connected in series in modules, creating an additive voltage. Connecting cells in parallel will yield a higher current;With high quality and stable quality. Our Cells can greatly improve the performance of Solar Modules.

Usage of Monocrystalline Solar Cells
Solar cells are often electrically connected and encapsulated as a module. Photovoltaic modules often have a sheet of glass on the front (sun up) side, allowing light to pass while protecting the semiconductor wafers from abrasion and impact due to wind-driven debris, rain, hail, etc. Solar cells are also usually connected in series in modules, creating an additive voltage. Connecting cells in parallel will yield a higher current; our solar cells have passed IEC Certification. With high and stable quality, our cells can greatly improve the performance of Solar Modules.
Applications of Monocrystalline Solar Cells
Assemblies of photovoltaic cells are used to make solar modules which generate electrical power from sunlight, as distinguished from a "solar module" or "solar panel". A solar array generates solar power using solar energy.
Packaging & Delivery of Monocrystalline Solar Cells
Carton Box Package and Deliver by air. It should be noticed that it should be avoid of water, sunshine and moist.
We have organized several common questions for our clients，may help you sincerely：
①What price for each watt?
It depends on the efficiency of the solar cell, quantity, delivery date and payment terms.
②How long can we receive the product after purchase?
In the purchase of product within three working days, We will arrange the factory delivery as soon as possible. The pecific time of receiving is related to the state and position of customers.Commonly 7 to 10 working days can be served.
③Can you provide the peripheral products of the solar panels, such as the battery, controller, and inverter? If so, can you tell me how do they match each other?
Yes, we can, we have two companies for solar region, one is CNBM International, the other is CNBM engineering Co.
We can provide you not only the solar module but also the off grid solar system, we can also provide you service with on grid plant.
④What is your warranty of solar cell?
Our product can promise lower than 0.3% open box crack, we support claim after opening the box if it has crackm color difference or sth, the buyer should give pictures immediately, we can not accept the claim after the solar cell has assembled to solar panel.
• Timeliness of delivery
• ⑤How do you pack your products?
We have rich experience on how to pack the solar cell to make sure the safety on shipment, we could use wooden box or pallet as buyer's preference.
⑥ Can you do OEM for us?
Yes, we can.
In order to reduce production costs, ground applications such as mono solar cell 156mm using solar grade silicon rods, materials performance has been relaxed. Some also use semiconductor device processing materials and discard the head and tail of silicon materials, solar cells drawn into complex dedicated silicon rods.
The silicon rods cut into pieces, usually 0.3 mm thick sheet. Processing mono solar cell 156mm, the first doping and diffusion in silicon, a trace amount of dopant is generally boron, phosphorus, and antimony. Diffusion is carried out in a quartz tube into a high-temperature diffusion furnace. Thus formed P> N junction on the wafer. Then using a screen printing method, fine with a good paste into a grid line printed on the wafer, after sintering, while forming the back electrode and the surface coated with antireflection gate line source to prevent a large number of photons It is reflected off the smooth surface of the wafer.
Thus, mono solar cells 156mm are produced. After single-chip random testing can be assembled according to the required specifications into a solar cell module (solar panel) by the method of series and parallel to a certain output voltage and current. According to user system design, solar cell components of various sizes square solar cells, also known as solar arrays. Photoelectric conversion efficiency of monocrystalline silicon solar cells is about 15%, the results of the laboratory also has more than 20%.
Crystalline silicon solar cell includes two battery and thin film batteries, their characteristics determine that they have an irreplaceable role in the different applications. However, the next 10 years the share of crystalline silicon solar cells although due to the development of thin film solar cells and other reasons decline, but its dominance is still not fundamentally changed; and thin film batteries can be solved if the conversion efficiency is not high, thin film batteries used in the preparation of equipment is expensive and other issues, will be a huge space for development.
