Product Description:

 

Polycrystalline Silicon Solar Cells:

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.

Polycrystalline Silicon Solar Cells Advantage:

•  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.

 FAQ

We have organized several common questions for our clientsmay help you sincerely

What price for each watt?

It depends on the efficiency of the solar cell, quantity, delivery date and payment terms.

How long can we receive the product after purchase?

R & D of Solar Electric Cell Closes to the market

Currently, the whole solar electric cell industry face with overcapacity, and actively expand the consumer sector will undoubtedly become an important means to resolve its excess production capacity.

In many cells, photovoltaic power generation module neatly arranged on the carport, the roof, sunny days to convert solar energy into electricity, supplying carport or household use, excess electricity can also be sold to the national grid and increase revenue.

In rural areas, the solar cell application prospect is very broad. As technology advances and changes in consumption concept, the solar cell is constantly "downsizing" has become an important feature for portable products and selling points.

The most common solar electric cell is the portable mobile power. By convert light energy into electrical energy and stored in the built-in lithium battery, solar mobile power can give mobile phones, digital cameras, tablet PCs and other products charge, both energy-saving and environmentally friendly.

Today, more and more people use solar electric energy products. These are stylish low-carbon products, as well as fun. College students said. She took a creative foldable solar lighting, lighting the top of the solar panels to provide electricity for a rainy day, folded and portable features and provides the possibility for outdoor use.

The development of mobile solar energy is a major opportunity for the industry. Mobile Energy as mobile communications and mobile Internet +, like, will change the traditional energy production and consumption patterns, so that the traditional centralized power into each individual can generate electricity, energy will be everywhere.
There are characteristics of distributed generation PV products, especially flexible products, and intelligent terminal products should be combined. When the arrival of the era of mobile energy, we will each bag, tent, clothes, utilities and electronic products are distributed by a flexible technological transformation and innovation, moving only the energy market in 2020 can reach the level of 1 trillion dollars.

Q:Where can I help my company to buy the 3 Busbar Solar Cell for our project?
We are a solar cell company based in China, and we are actually promoting our product on alibaba, where you can find the TP-125M 6.5''x6.5'' 3-busbar solar cell be your choice.
Q:How does the solar panel produce it yourself?
 The second step: the use of natural fuel for the titanium dioxide coloring, the fresh or frozen black plum, plum, pomegranate or black tea, with a tablespoon of tax for extrusion, and then put the titanium dioxide film for coloring, about 5 Minutes until the film becomes dark purple. If the two sides of the film coloring uneven, you can put in the soak for 5 minutes, then rinse with ethanol, and gently wipe with soft paper.
Q:What is the solar cells market in China?
As far as I know, it's developing very well. Not only in terms of the technology but also in terms of the sales revenues. Many solar cells factories are located there
Q:How does the solar cell work in terms of photochemical conversion?
Photovoltaic power generation principle is the photoelectric transformation, we all know, the semiconductor is between the insulator and the conductor, with a certain conductive properties of the material.
Q:How can I understand the working principles of solar cells?
Read as many books as you can.
Q:How does the photovoltaic cells work?
Photovoltaic solar cells are the thin silicon chips that transform the sunlight into electricity in a scientfic way.
Q:Is solar cell technology very developed and v applied to life a lot?
Ever since scientists discovered the solar cell, it has been very much a part of our life.
Q:How can I calculate the cost of using solar cells if I put a fully-functional solar system in my house?
On average the total cost of solar installation can be between $15,000 to $29,000 for systems sized between 4kW and 8kW.2
Q:I studied very hard at school, but I just can not figure out how solar cells work, anybody can help me with that?
The process of solar cells' conversion first requires a material which absorbs the solar energy (photon), and then raises an electron to a higher energy state, and then the flow of this high-energy electron to an external circuit. Silicon is one such material that uses such process.
Q:What is a polymer solar cell and how does it work?
Polymer solar cells are lighter than other silicon-based solar cells.
