Manufacture of functional tetrahydroquinoline dye containing thiophene bridge bonds.
- 2006
-
Patent (populärvet., debatt m.m.)abstract
- The title dye employs 1,2,3,4- tetrahydroquinoline and its derivates as the electron donor and a different no. of thiophene units with adjustable absorption spectrum and fluorescence emission spectrum as the bridge bonds to connect different electron-absorption groups. The dye can be expressed by a general formula I, wherein R1 is C1-C20 linear alkyl or branched alkyl; R2 is H, or C1-C3 linear alkyl or branched alkyl; R3 is H or methyl; R4 is H, C1-C20 linear alkyl or branched alkyl, amido, alkoxy or halogen; R5 is PO(OR')2, -COOR', -SO2OR' or CN, wherein R' is H, or C1-C30 linear alkyl or branched alkyl; m=0 or 1; n=1-6. Tetrahydroquinoline as a chromophore has a good electron supply capability. Thiophene units connected with different electron-absorption groups have high electron-cloud d. and particular optical characteristics and electron transmission capability. The dye has the advantages of high optical stability, high thermal stability, high chem. stability and good photoelec. character, and can be used for dye sensitized nanocrystaline solar batteries and photoluminescent or electroluminescent testing kits.

Multilayer transparent conductive substrate for solar cell with reduced surface resistance and good corrosion resistance.
- 2009
-
Patent (populärvet., debatt m.m.)abstract
- A composite transparent conductive substrate for photoelec. device (solar cell) comprises transparent base (made of glass, plastic or transparent polymer); high-cond. grid mesh (made of silver, stainless steel, iron-nickel alloy, etc.) formed on the transparent base via printing, electroplating, sputtering, etc.; and transparent conductive film (made of tin-doped indium oxide, fluorine-doped tin oxide, etc.) covering the transparent base and encasing the entire grid mesh. The inventive substrate has good corrosion resistance, reduced surface resistance, excellent cond., and wide application in dye-sensitized solar cell, silicon thin film solar cell, copper indium diselenide solar cell, compd. thin film solar cell and org. thin film solar cell. For dye-sensitized solar cell, the invention can simplify the manuf. process and improve the performance and stability. [on SciFinder(R)]
