IMEC to develop full-printed solar cells for photovoltaic conversion efficiency of 3%

Published by admin under battery tips

IMEC is an independent research institution located in Belgium (Belgium) of Leuven (Leuven), in the nano-electronics and nano-technology leadership position in the world, and also the Netherlands, the United States, China and Japan to set up an office, with more than 1,600 employees, including the Mill and Visiting Fellow, in 2007 brought revenue for the country about 2.4 billion euros. They are mainly resolved on the basis of academic science and industrial manufacturing process differences between the unique processes, systems technology, the patent group and the most advanced equipment. Today, they verify that the entire solution process of the organic solar cells.
“We are developing a way for the whole solution process of the organic solar cell can be high-quality electric sexual contact, so this battery has a 3% of the electricity conversion efficiency.” IMEC said so. Research laboratories in Belgium and the use of previously developed the initiative for organic solar cells sprayed layer coating technology, “This method is suitable for mass production of volume after volume (roll-to-roll) manufacturing process, so whether it is or can be hard Flexible substrates can be, fast and cheap manufacturing large-area organic solar cells. ”
Metal electrodes formed in the organic layer on top of semi-review body, electric contact must be allowed between conductivity between 104 and 106S/cm, and has high stability, has been through the commercialization of nano-particles of silver ink, under nitrogen at the use of spray gun spray painted, and then by 100 ~ 180 ℃ sintering, so that molten particles to form a continuous film. IMEC refers to “advanced technology throughout the ink-jet printing can be printed or manner of the realization of large area, and with volume on the volume of equipment to complete production.” Solution in order to complete the whole process of organic solar cells, IMEC put forward a reverse structure, that is, before the formation of electron collection layer (cathode), then is the semiconductor layer, and then coated with the anode. “If the cathode in the semiconductor layer after the formation of the electron layer resistance files must be in active layer above can avoid the type of metal electrode into the process of damage caused.”
The whole solution process, the barrier layer (usually the use of zinc oxide, ZnO, or titanium dioxide, TiO) formation, brought about by surface morphology, resulting in subsequent phases of silver nanoparticles to penetrate, resulting in cell conversion efficiency decreased. The anode in this area, due to electric-hole barrier layer (commonly used poly -3,4 - dioxo-thiophene ethylene [poly (3,4-ethylenedioxy-thiophene)], poly styrene sulfonic acid [poly (styrenesulfonate)] or both mixed-doped [PEDOT: PSS]) have adequate thickness, formed in the organic layer can protect the damage that may occur. Anode and then sprayed on the silver particles on, can be the whole solution process of the organic solar cells. All the organic materials such as poly (3 - f alkyl thiophene [poly (3-hexyl thiophene), referred to as P3HT] and 6,6 - phenyl-methyl-C61 D [(6,6)-phenyl C61-butyric acid methyl ester, referred to as PCBM) can be dissolved in solution and deposited on indium-tin oxide glass substrate.
Components of the photoelectric conversion efficiency is about 3%, equivalent to the general use of components made of evaporation, but the short-circuit current is higher than 10mA/cm2, when the nano-particle sintering temperature dropped to below 150 ℃, then can use flexible substrates, including polyethylene naphthalate [polyethylene naphthalate, referred to as PEN

EU battery law traders improve their sense of responsibility

Published by admin under battery tips

The EU will launch a battery and battery with the new directive. The directive aims to reduce harmful batteries and battery production, improve the old batteries and battery recycling, treatment and recycling rates, and providing information to consumers and encourage them to buy more battery longevity and environmental protection.
Batteries Directive and the “waste electrical and electronic equipment Directive” (WEEE) is very similar to the provisions of producers have to register at the relevant departments, distributors have the responsibility of recycling old batteries, as well as each section of the dell laptop battery  or batteries have to achieve very high recycling rate and so on. In addition, the electrical requirements of the Directive should be designed to enable easy removal of batteries so that consumers at any time put into the old battery collection points.
Batteries Directive are as follows:
1. Directive prohibited alcohol concentration of more than 0.0005% mercury and cadmium content of more than 0.002% of the sale of batteries and inspiron 6000 battery. Alarm systems, medical equipment and wireless power tools used by the exception of batteries and battery.
2. Has the responsibility of distributors to recall the inspiron 9300 battery  run out, so the duty to inform consumers. 2012, the EU Member States the minimum recovery rate should reach 25% in 2016 to reach 45%.
3. All manufacturers to be registered. EU member states of the registration scheme should be consistent, so that manufacturers can hardly evade duty.
4. In the last draft of SMEs in the recycling can enjoy the treatment of certain immunities, but now these exemptions have been slashed. The new draft to clarify the low-volume 310-6321 manufacturers at the circumstances under which investors will be exempted from duty.
5. Recycling rate, lead-acid batteries and battery with an average weight of 65%, nickel-cadmium batteries for 75%, 50% for other battery.
6. Designed electrical manufacturers should ensure easy removal of batteries and 310-6322.
7. In the EU member states put the directive into national laws and regulations one years later, manufacturers have to label batteries and battery performance.
This is to encourage consumers to buy a better performance, longer battery life.
After the promulgation of the new directive, EU member states will have two years to put orders into the national laws and regulations. The directive will also repeal the existing d5318 Directive (91/157/EEC) and its amendments (91/101/EEC and 93/86/EEC), replaced by a single command.

Car’s battery maintenance in Summer

Published by admin under battery tips

Commonly used in car batteries is currently divided into two categories, one category is an ordinary battery; The other is maintenance-free battery.

Ordinary batteries generally used in many trucks, farm vehicles, earth-moving machine. Maintenance-free battery is used in cars, electric cars, cameras, posts and telecommunications equipment, electricity than ordinary life (1 ~ 2 years) than double. However, this battery when in use must also pay attention to maintenance.

Automotive repair expert master Chiang told reporters, start start-up time for each car should not be more than 3 ~ 5 seconds, re-start time interval of not less than 10 seconds. Automotive regular short-distance driving or frequent start-stop, would result in a long time battery charge insufficient to shorten the service life. On the road to good at 50 ~ 60 kilometers per hour speed stability 30 minutes, you can give sufficient time to recharge the battery.

In addition, the day-to-day driving in the car before leaving, check to ensure that all vehicle lights and other electrical appliances (such as radios, CD) have been closed, parked a long time because the battery will do. If you run out of battery before use other backup battery electric (wire) to start, start as far as possible after the constant speed of at least 30 minutes, the battery has sufficient charge time. If the car do not have long-term placement should be on the car full charge. Every month car mobilized, medium-speed operation of 20 minutes.

Car batteries to the regular maintenance, carefully check whether the battery bolt to plug the vents. Battery charging at the normal will have many hydrogen and oxygen precursors, once the exhaust valve failure or blockage, internal pressure is too large, may cause an explosion. Therefore, every 15 to 30 a day to check.

Do you know how the proper use of electric vehicle batteries it?

Published by admin under battery tips

In recent years, electric bikes become the preferred means of transport for urban and rural masses. Electric vehicles to battery-driven, battery electric vehicles are the heart. Recently, because of stereotype, thus pushing up the price of the battery more than the price of the motor, electric cars to become the most valuable part. The proper use and maintenance of batteries, to keep the battery in good condition and extends battery life cycle, are the key to reducing cost. To this end, the reporter interviewed a Erkang Jinan battery manager Yao repair centers.

Manager Yao talked about the following experience:

First, buy a car they should pay attention to the quality of the battery. Buy a car to buy store brands at original vehicle; assembled car to open the battery box to check the battery brand and the factory date (batteries are manufactured on time code); replacement of new battery when the battery brand formal election; purchase and replacement of Remember to ask for a new battery invoices, invoices should be marked on the battery durability.

Second, the hard charging. Electric cars in use, as far as possible the timely charge, otherwise battery life will be reduced 1 / 3, such as battery re-charge electric show losses are misunderstanding.

Three, shallow place. To avoid excessive battery discharge, in the cycling process, the instrument showed that when undervoltage manpower to help move as much as possible, do not rely on battery-electric pick-up in the virtual ride; while minimizing overloading or climbing steep slopes, to avoid large current discharge battery for long battery injury.

Four, to avoid prolonged losses placed electric battery. If time does not use electric cars should be placed full battery, during which time a month to ride, and then filled with electricity.

Friday, the use of high-quality charger. Chargers on the quality of the merits of the relationship between battery life greatly, the general battery charger happened drum kits are created. Usual to observe the charging time, if the charging time suddenly shortened or extended, we must pay attention to timely find out why.

Sixth, to conduct regular maintenance of batteries. New battery in the use of 8-12 months to pay a repair shop and pulse in addition to sulfide. The apparent failure of the battery also should not be lightly abandoned, if not physical damage, repair of used batteries can be repeatedly used, so make the best use, so that both environment-friendly, but also greatly reduced cost.

Use the battery properly

Published by admin under battery tips

Battery as a power source for electric cars, but you should never pay attention to understand the relevant knowledge, to safeguard them, not because the use and maintenance shall not be treated and let the battery “injured.” Experts remind that motorists should pay attention at the following points:

First, not overweight traveling. The second is a new battery charging at first will be to ensure adequate electricity. Regardless of distance traveled far and wide, use immediately after charging, with the release with the charge, not to completely run out of power before recharging thought. Vehicles such as long-term non-use, but also to guarantee a monthly supplement electricity. Three are not speeding. Speeding not only affect traffic safety, but also caused by electrical overload of work, potentially shortening the hp laptop battery life.

In addition, to develop good habits are also important. For instance, electric cars will not be too cold on the place, as it would affect the battery’s charge-discharge performance. Winter, it is advisable to promote electric cars interior. Such as moving less than electricity, to make full use of human cycling, so as to reduce the burden on the battery. On the bridge, uphill, against the wind driving the use of pedal power to avoid battery damage caused by impact. These good habits on to extend the hp f1739a life are a lot of good.
