According to the American physicist organizational networks reported on January 4, Compaq EVO N410c Battery, Compaq EVO N600C Battery, Compaq EVO N610C Battery, Compaq EVO N620C Battery, MIT researchers have demonstrated a new printing technology that can print solar cells to thin, soft materials such as ordinary toilet paper. Although the use of toilet paper do not like the actual base of the solar equipment as efficient, but it is a low-cost printing technology, widely used in various materials reflect diversity.
New technology called oxidative chemical vapor deposition (oxidative chemical vapor deposition, oCVD), gasification of the raw material monomer and oxidant in the substrate material after the jet, after the polymerization of monomer and oxidizer meet to form a PEDOT film. PEDOT films can be conductive, by controlling the substrate temperature, the formation of small nano-porous, can be more tightly fixed conductive silver particles can be enhanced conductivity of PEDOT films of 1000.
MIT chemical engineering professor and graduate student Karen Gleason, who Maier Spartak fragile soft material in a variety of shows on the solar cell printing technology. Such as the restaurant used to make spring rolls of rice paper, usually melts when wet, and the new technology is the drying of solvent-free, after the rice paper can be printed to keep intact. They are still wrapped in plastic yarn Wong demonstrated a new printing technology, this material does not absorb water, generally above the graffiti in the printing process very difficult.
Printed solar cells can resist the large bending stretch. The researchers published in the experiment will be a plastic substrate material bent into radius less than 5 mm, found that its efficiency could meet 99% of the time without bending. Compaq EVO N610C Battery, Electrodes can also be curved stretch while maintaining electrical conductivity.
To further demonstrate the robustness of the technology, Meyer Spartak-printed solar cells will be a paper presentation of a paper airplane, even so, paper airplane can also generate electricity.
The researchers noted that because of opaque, paper is not the most representative of the ideal optical substrate material. But for the manufacture of solar cells for a wide range, looking for a low cost, flexible and soft, flexible material is very useful. In addition to solar cells, the technology is also applicable to other electronic devices produced in order to achieve a soft fabric fibers and other electronic printing.

indicator. Acer 90.NBI61.011 battery The IC from 6V to 28V power supply, its synchronous DC / DC step-down mode allows up to 96% efficiency, and LTC4006 can be accounted for as much as 98% empty rate job, so the total space to permit the rate of 0.5 V pressure job, as well as from the low-voltage wall adapter charger. In order to improve safety during charging, LTC4006 has a battery temperature monitor as well as overvoltage and overcurrent protection. The target application has memory backup systems, portable medical and automotive diagnostic tools, GPS, and notebook and notebook PC satellite a60-662 battery.
LTC4006 has a quasi-constant frequency and constant off-time architecture, the architecture in the use of ceramic capacitors, even if circumstances do not produce audible noise. This IC has three models, respectively, Acer BTP-APJ1 Battery, Acer BTP-AQJ1 Battery, Acer BTP-ARJ1 Battery, with 8.4V (2 cell), 12.6V (3 cell) and 16.8V (4 cell) floating voltage, and its accuracy are ± 0.8%. Available charge current programming resistor to ± 4% typical accuracy. Electricity consumption for the instructions, a special feature of this charging current is expressed as micro-controller or A / D converter voltage. Resistor can be set using the total charge time for 1-3 hours. LTC4006 automatically recharge and trickle charge function.
LTC4006 job at – 40 ° C to 85 ° C temperature range to 1000 as a unit bulk purchase, each priced at 3.60 U.S. dollars.
