    摘要: 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.

    摘要: 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.
