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

Q:Solar energy products, that is, I would like to open a home solar products Daquan
Photoelectric, two large blocks of light and heat, I think it will be a complete. But a lot of financial strength to do it
Q:Solar energy application technology, there is no prospect
At present the solar energy situation is not optimistic, the Americas and Europe has Chinese solar "double reverse" and China internal and not good, can not be the own production of solar energy products consumed, resulting in pile up in excess of requirement. Therefore, many Chinese solar manufacturers have closed down.
Q:Household solar energy productsThe product can be used at home, do not mention the solar energy, answer the water heater
What solar products:The current solar products include: solar water heater, solar lamp, solar battery, solar power, solar fan cap, solar fan, villa solar power systems, solar flashlight, solar charger, solar cars, solar powered aircraft etc..The main components of solar water heater: flat solar water heater, vacuum tube solar water heater, wall mounted solar water heater.Solar lights include: solar street lights, solar garden lights, solar home lighting.Solar cells are: silicon solar cells, multi compound thin film solar cells, nano crystalline solar cells, organic solar cells.
Q:Consumer behavior analysis of solar water heater
Consumer behavior analysisConsumers in the purchase of products, often have to consider the physiological needs, safety and health needs, psychological factors (environmental sustainability, energy saving, economic and other factors), at the time of purchase, often face 5 kinds of risk perception: one is the financial risk, that there may be a waste of money; the two is the function of risk, if function is not so good, or no brochures and advertising on the good; three is the physiological risk, looks a bit dangerous, afraid might get hurt; four is the social risk evaluation from fear surrounding friends not good; five is the psychological risk, because buy guilty, it would be irresponsible. For solar products, because the product and installation specification is not perfect, the implementation of the implementation of the lack of supervision, consumers lack of understanding of the core technology of solar energy, solar water heater does not have a clear understanding, in order to "Huiyanshizhu, consumers in the purchase, will be the main value of the brand, including corporate brand, product brand and service brand is the basis for the choice of consumers, because the brand is a commitment to consumers, its excellent quality, strong customer service service will guarantee the legitimate rights and interests of consumers; the value of quality products, to effectively meet the target market demand, such as the market part of the solar water heater can meet the demand of hot water in summer. But one winter has become idle goods, and even pipe cracking; value service, service satisfaction value, such as" Baidu service 100% satisfaction, service a little more satisfied with a little, through the service to reduce the risk of consumer awareness of the purchase.
Q:Product category and comparison of solar thermal utilization
Why choose a new type of efficient flat plate solar water heater (device) system?In recent years, the use of solar thermal products in China has been rapid development. In the solar water heater manufacturing, use and market share, China has far ahead. However, due to the use of solar thermal products in domestic vacuum tube based, in full swing in the development of the industry, but also exposed a lot of worrying problems.
Q:How to make better use of solar energy
The first stage (1900~1920 years) at this stage, is still the focus of solar power plant solar energy research in the world, but the spotlight by diversification, and began to use the flat plate collector and low boiling point device, gradually expanded, the maximum output power of 73.64kW, with the objective clear, cost is still high.
Q:Outdoor solar energy products how to process the level of IP65
First, the packaging process,Design must consider the requirements of water, the structure can not be set up obstacles
Q:New solar productsI want to know the new solar energy
Solar door lock lampThis is a new type of solar lock lamp solar panel for charging the battery, a LED lamp lighting, a full charge can continuously light 720 times, each time for 10 seconds, 10 seconds will be automatically extinguished, this time is enough for you to insert the key inserted the place.
Q:Solar electric vehicle charging device
Electric vehicle using solar silicon and polysilicon combination surface for Ling lighting plate, high quality and high efficiency crystalline silicon plate, the weak light response is very good, high photoelectric conversion efficiency, both indoor and outdoor sunlight, can be 24 hours of uninterrupted charging for electric vehicles to absorb light, can meet the different electric vehicles with electric load.
Q:What are the disadvantages of traditional solar water heater
We now have a factory in Wuxi, the production of solar water heaters, the core components - superconducting heat pipe, so that the product in place. Heat pipe is a vacuum glass tube inside, no leakage, no water absorption of solar heat, but the use of dark metal materials such as heat transfer, heat transfer efficiency is high temperature superconducting material.
