  • Publication number: 20150101530
    Abstract: A method of recycling a solution, the method including: filtering a solution used in chemical bath deposition; reinflowing the filtered solution to a bath; and inflowing an alkali solution to the bath to maintain a concentration of an alkaline material in the filtered solution in a range of about 1.0 M to about 3.5 M, is disclosed. A solar cell formed by the method and a deposition apparatus are also disclosed. By the method of recycling a solution, a solar cell including a buffer layer formed with a solution which has been used multiple times may be formed to have an efficiency almost the same as that of a solar cell including a buffer layer formed with a solution provided for the first time before filtering.

  • Publication number: 20140287540
    Abstract: A deposition apparatus and a method for recycling a solution. The deposition apparatus includes a bath in which a solution used in a chemical bath deposition (CBD) method is filled, a tank in which the solution used in the CBD method is temporarily stored, and a filter unit for filtering the solution stored in the tank to be reused in the CBD method again. Thus, when a buffer layer is formed by the CBD method, the number of times of reusing the solution for forming the buffer layer may be increased.

  • Patent number: 7662317
    Abstract: Provided is a dispersant including a hydrophobic moiety with a branched alkyl group and an arylene group and a hydrophilic moiety with an alkylene oxide group and a carboxylic acid group. The alkyl group is a substituted or unsubstituted alkyl group of 5-30 carbon atoms, the arylene group is a substituted or unsubstituted arylene group of 6-30 carbon atoms, and the alkylene oxide group is a substituted or unsubstituted alkylene oxide group of 2-10 carbon atoms. The dispersant has good dispersibility, and a low residual carbon content after sintering. Thus, a paste composition including the dispersant can maintain a low viscosity and disperse many inorganic particles. Thus, an inorganic device prepared using the paste composition can have a low residual carbon content and a high packing density.

  • Publication number: 20070001608
    Abstract: Provided is paste composition that includes inorganic particles, an organic solvent, and a phosphate ester dispersant having a hydrophilic moiety with an alkylene group. The dispersant has good dispersibility and strong viscosity decreasing ability, so that contains more inorganic particles than a conventional paste composition at the same viscosity. Thus, a display device prepared using the paste composition has a better packing density.
