Product Description:

Back contact solar battery components for good appearance, shading, high efficiency and less packaging

The advantages of small loss of attention, the Dutch national energy research center (ECN) study machine, etc

Structure is proposed based on an encapsulation of conductive foil lines connected, the use of conductive back substitution

The existing conventional polymer backboard, the basic structure of the products are: copper conductive back/EVA/of drilling hole

Conductive adhesive/cell/EVA/tempered glass, but the current conductive back is expensive and it is on the market

No mature products, and other conventional photovoltaic modules is: this kind of back contact components

Bus layer below the encapsulation EVA, close to the back surface, easy to produce water vapor intrusion and local

Discharge phenomenon, therefore, the structural reliability of special this component has yet to be further verified.

Back contact solar cells is aiming at the shortcomings of the existing technology and component technology

Provide a low cost, easy to implement and good reliability back contact solar arrays

A technology. Compared with the existing technology, the obvious advantages of zyprexa technology is that the back contact cells

Components using the conventional back and packaging materials on the market, on the one hand, reduces the cost of materials,

Simplify the production process, on the other hand also ensures that the component reliability and stability, have very much

Conducive to back contact photovoltaic modules of large-scale production needs.

Conducive to back contact photovoltaic modules of large-scale production needs.

In particular, back contact the solar cell component technology has the following advantages:

1. The main gate line, less decrease with silver

2. The shading area reduced, efficiency improved

3. No string of welding, series resistance is small, encapsulation losses small

4. Good heat dissipation, the same power can be more electricity


5. There is no welding, no stress, enhanced reliability

6. No welding, silicon wafer can be thinner

7. Use the conventional back and packaging materials on the market, reduce the material cost, simplify
