What is the next dye-sensitized solar cells
In the “American Chemical Society,” a new paper published in the journal vgp-bps2 , vgp-bps2a, they introduced the use of zinc stannate particles of a dye-sensitized solar cells, but this battery does not use nanowires, their efficiency is 3.8%. Now they are combining these two kinds of strategy research, namely the use of zinc oxide manufacture of tin salts and other nanowires.
They also also exploring the possibility of using nano-trees vgp-bps2b , vgp-bps2c – nano-wires shaped like tree branches like. Professor Wu said, “We ask ourselves, what structure is to absorb light and transfer the best current structure of it, that is tree-like structure! Leaves provide a large surface area to capture light, the branches will be transferred to the nutrition roots. In our dye-sensitized solar cell design, dye particles will provide coverage of the surface area, nano-trees would grow among the leaves on these branches, transmission electron. ”
Therefore, the next dye-sensitized solar cells will grow a tiny pink “tree”, but other colors are also possible. The researchers are studying to work better in the new dyes and dye compounds.

DRAM price rebound(A)
Local 4 this week, due to rising prices of computer memory chips Sony VGP-BPS8 Battery, including South Korea’s Hynix Semiconductor Sony VGP-BPS9 Battery, including major Asian chip makers showed a price rise to varying degrees.
According to DRAMeXchange figures released this week, 512MB DDR2 memory, three spot prices rose 17%, which is also a weak memory market, the price of the rare recent rebound phenomenon. Due to increased production coupled with lower than expected market vgp bps2c demand, DRAM chip prices have fallen sharply this year, the major memory chip makers are therefore affected in varying degrees.
Industry analysts pointed out that DRAM spot prices this week, three-rebound might be only a temporary phenomenon, but also strengthened their full recovery of the memory market confidence. Hyundai Securities analyst Jay Kim said that day, according to past experience, the entire memory Sony vgp bps2c market experienced a sharp decline in spot prices will be followed by recovery, if the contract price and the spot market, consistent upward trend, then the DRAM chip prices will start to rise, while the memory makers The third quarter is expected to improve.
Second only to Samsung Electronics as the world’s second largest DRAM chip maker VGP-BPS8, Hynix Semiconductor shares rose 4.67 percent Thursday, rose to ₩ 33,650; Japanese DRAM maker Elpida Memory chip shares rose 3.47%, rose to ¥ 5670; China Taiwan DRAM chip maker Powerchip Semiconductor and Nanya Technology shares were up 2.26% and 2.78% with VGP-BPS2A.
