Q1: Why buy Materials & Equipment from OKorder.com?
A: All products offered byOKorder.com are carefully selected from China's most reliable manufacturing enterprises. Through its ISO certifications, OKorder.com adheres to the highest standards and a commitment to supply chain safety and customer satisfaction.
Q2: What is a solar cell?
A: A solar cell is an electrical device that converts light energy directly into electricity by a phenomenon called the photovoltaic effect. When exposed to light, solar cells can generate and support an electric current without being attached to any external voltage source, but do require an external load for power consumption.
Q3: What are the advantages and disadvantages of monocrystalline solar PV cells?
A: Monocrystalline solar cells are the most efficient type of PV cells, with the exception of CdTe thin film solar PV cells. As a result, monocrystalline solar cells are more expensive when compared to almost all other types of cells.
Q4: What is the typical service life of solar PV modules?
A: The typical life of a PV module is 25 years. However, superior quality PV modules boast service lives up to 35-40 years (electrical generating capacity is often reduced, however by that point).
Q5: What certifications do you have?
A: We are specialized in the photovoltaic field, with a focus on solar cells, modules and photovoltaic power generation systems. We employ advanced monocrystalline and polycrystalline silicon solar cell manufacturing equipment, producing highly efficient and reliable products sold in Europe, the Americas and Australia. Our company has passed ISO9001 quality management system certification, and our products have obtained TUV-IEC, CE, UL certification.
Q6: How do we guarantee the quality of our products?
A: We have established an advanced quality management system which conducts strict quality tests at every step, from raw materials to the final product. At the same time, we provide extensive follow-up service assurances as required.
Q7: How soon can we receive the product after purchase?
A: Within three days of placing an order, we will begin production. The specific shipping date is dependent upon international and government factors, but is typically 7 to 10 workdays.

Brief introduction of Monocrystalline Silicon Solar Cells
Monocrystalline silicon solar cells based on high-purity silicon rods as raw material for solar cells, is currently the fastest development of a solar cell. Its structure and the production process has been finalized, the products have been widely used in space and on the ground.
In order to reduce production costs, ground applications such as solar cells 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. After polishing, cleaning and other processes, the raw material will be made of silicon.
In the processing of making solar cells, 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, the monomer monocrystalline silicon solar cells 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. Finally, package the frame and materials. 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 are about 15%, the results of the laboratory also has reached more than 20%.
