ZONEPV displayed the high conversion efficiency of silicon-based th

2010-03-09 19:21:23

Jiangsu from China Arts photovoltaic (ZONEPV) displayed the conversion efficiency of amorphous silicon-based thin-film solar thinkpad t40 battery panels open is 10.28% in the PV EXPO 2010 Third International Solar Exhibition" . When the silicon-based thin-film solar cells of exhibitors dropped, the companies have demonstrated a high efficiency products.

The thin-film solar cells ,like the klic-7004 battery ,is made of amorphous silicon PV panel display and micro-crystalline silicon in series. Size is 1109.6mm × 1309.6mm. Opening the Ministry of stable module conversion efficiency is 10.28%, open voltage is 183.025V, short-circuit current is 1.1106A, form factor (FF) is 0.6883. The maximum output power is 139.907W, panel conversion efficiency is 9.6%. The conversion efficiency will be higher as a tandem-type thin-film silicon solar cell for thinkpad t400 battery. Butmeasured value temperature is 21.3 ℃ .

Variety is a one-stop production of amorphous silicon-based photovoltaic thin film solar cell and module manufacturers. a production base is about 100km north of Nantong City in Shanghai across the Yangtze River . The company is currently building the size of annual production capacity of 80MW manufacturing facility has been completed the size of 30MW.

"PV JAPAN 2009" displayed various manufacturers competing silicon-based thin-film solar cells,such asthinkpad t61 battery and vgp-bps2a battery ,in June 2009. But this is completely different, this type of solar cells exhibited drastically reduced. In particular, many manufacturers are not participating device manufacturers.

Japan are developing a new solid-state lithium-ion battery

2010-03-09 19:21:50

Japan engaged in petroleum and petrochemical business, and its Idemitsu Kosan Company March 8, 2010 announced that it was accelerating the development of solid-state lithium-ion vgp-bps2c battery phosphorus sulfide solid electrolytes (Li2S-P2S5), the company will be officially launched in 2012 solid-state lithium-ion batteries The new electrolyte.

Idemitsu Kosan Co. as the company confirmed that lithium sulfur rechargeable lithium-ion apple a1185 battery battery (rechargeable batteries) are potential as electrolyte materials, and are currently being evaluated with the PPS resin to produce high-purity lithium sulfur technology. Since 2006 the company set out to develop a solid electrolyte based on the material will be highly applicable to hybrid vehicles and electric vehicles, at room temperature, the lithium-ion conductivity is 4 × 10-3S/cm in developpment of the electrolyte,, the equivalent of lithium-ion secondary aspire 3000 battery is applied to the use of liquid organic electrolyte.

However, compaired to the liquid organic electrolyte,solid electrolyte has an excellent stability, even at high voltage and temperature, it can also resist deterioration or evaporation. Solid electrolyte can also avoid security risks, such as solvent leakage and fire, which also has a wide range of construction of technical merits. With Idemitsu Kosan's development of solid electrolyteTravelMate 2440 series battery are also available at low temperatures below 0 ° C run.

Phosphorus sulfide solid electrolyte can be used asd a variety of electrode materials, and can have a high capacity cathode electrochemical nature.

Idemitsu Kosan has demonstrated its lithium-sulfide electrolytes A6-size (105 mm × 148 mm) thin-layer solid-state lithium-ion (Li-ion) batteries.

the output voltage of A6-size pavilion zv6000 battery with cascade double-click is 14-16V, solid electrolyte film thickness is about 100 μm, film thickness will be further made into 10-20 μm, it can reduce resistance, and explore the optimization of electrode materials.
