Brief Introduction of Solar Cells

A solar cell, is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon. It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. Solar cells are the building blocks of photovoltaic modules, otherwise known as solar panels.

Introduction of our Company

We are a producer of bifacial photovoltaic (PV) crystalline silicon solar cells that provide 25% and beyond more electricity per cell at a standard cell production cost, lowering the LCOE, doubling the PV project IRR and cutting its payback time.

Our bifacial cell delivers industry leading equivalent cell efficiency with over 21% today and a target of over 24% in the near future. Our cell is the best solution for flat rooftop and ground installations, as well as for PV trackers, sound barriers, car ports, facades and some forms of BIPV.

Our manufactures its bifacial high-performance, high-quality, mono c-si cells in its 30 MWp/year plant in Heilbronn, Germany and is on track with a four-year target of reaching a bifacial cell production capacity of 500 MW/year worldwide.

The PV market has turned into a commodity market where most vendors offer similar products without differentiation. Cell efficiencies are reaching a ceiling and current players are only able to offer marginal improvements through higher production costs. Our bifacial cell offers a disruptive solution targeted at the mainstream of the PV value chain; p-type, 6’’ silicon cells, with an unprecedented combination of high efficiency and low production cost.

Advantage of Polycrystalline Solar Cells

1.     Tire-1 Solar Cells’ Manufacturer Quality Guarantee. With a complete and sophisticated quality government system, our Quality Management have arrived world’s leading place. Customer can receive Tire-1 Cells Maker’s Quality Standard Products.

2.     Trusted Warranty. We can supply trusted after-sales service to our customer. If our cells are found not in conformity to the specification of manufacturer, or should the inspected quantity found in shortage, or should the packing found damaged, the buyer has the right to claim to the seller. The claim, if any, should be presented to seller within 30 days after cargo's arrival date to the port, together with related inspection report and photos issued and provided by a reputable independent surveyor such as SGS.

3.     World’s Leading Manufacturer Equipment. We imported the newest and leading production equipment from abroad. Advanced equipment can guarantee the stable quality of cells. Auto production line can also save labor cost which will further cut our production cost.

4.     Bulk supply: With the production capacity of 500MW, we can produce large quantity every month. This can satisfy most customer requirement.

Usage of Polycrystalline 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 Polycrystalline 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 Polycrystalline 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 clientsmay help you sincerely


1.     What’s price per watt?

A: It’s depends on the quantity, delivery date and payment terms of the order. We can talk further about the detail price issue. Our products is high quality with lower price level.


2.     Can you tell me the parameter of your solar cells?

We have different series of cells with different power output, both from c-si to a-si. Please take our specification sheet for your reference.


3.    How do you pack your products?

We have rich experience on how to pack the panels to make sure the safety on shipment when it arrives at the destination.


4.     Can you do OEM for us?

Yes, we can.


5.    How 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 perfect time of receiving is related to the state and position of customers. Commonly 7 to 10 working days can be served.

Q:Where and how can we find the best solar cells suppliers?
I usually use to find the solar cell suppliers here: 1, 2, 3.
Q:What is the current situation and the recent progress space solar cells in China?
In China, the space solar cells technology is considered to be very important at the current situation, and it has already developed very dramatically after China gave financial support to the space solar cells projects.
Q:Where and how can I find more information of Photovoltaic Cells Solar Panels? Can anybody share more about that?
Photovoltaic cell is actually a vital elements in the PV system, without it, the PV system can not function properly and generate the power.
Q:What is a polymer solar cell and how does it work?
Polymer solar cell is a type of flexible solar cell made with polymers.
Q:Are there any library or exhibition halls where I can show students at school how the solar cells works?
Why don't you arrange a tour to the solar cell library in downtown?
Q:Is that true that the price of solar cells will be reduced in the coming year?
TrendForce, a professional survey firm based in Taiwan announced March 10th : because the global market demand for solar cells is declining it is very possible that the price of solar will eventually goes down.
Q:How to define the poly solar cells as the A Grade one?
You can try to define it through the three factors: Efficiency, stability and durability.
Q:What is the working principle of a solar cell?
It's not easy to explain in a simple way.
Q:Which brand of the solar cells is sold with the lower price on the market? Which brand is more practical for the countryside?
Our price of the solar cell is low and very competitive in the market, but we can still guarantee you that we provide you the best quality.
Q:Where can I get a competitive price for this solar cell? The 2bb/3bb polycrystalline solar cell panel?
You can consult with your solar cells supplier in the local market, where you might find some useful information to get the right dealer.
