  • Publication number: 20130118403
    Abstract: A chemical bath deposition system is used for forming a buffer layer on a back electrode substrate having a photoelectric transducing layer. The chemical bath deposition system includes a chemical bath tank, a chemical-solution purification device, and a dosing device. The chemical bath tank is used for storing a buffer-layer solution including cation and anion. The cation is adapted to react with the anion to form the buffer layer when the back electrode substrate is immersed in the buffer-layer solution. The chemical-solution purification device is communicated with the chemical bath tank for removing residual cation to obtain a purified solution after the cation reacts with the anion to form the buffer layer. The dosing device is for performing compensation of the cation according to a component ratio of a purified solution.

  • Publication number: 20130122190
    Abstract: A chemical bath deposition system is used for forming a buffer layer and a ZnO window layer on a back electrode substrate having a photoelectric transducing layer. The chemical bath deposition system includes a first bath tank and a second bath tank. The first bath tank is used for storing a buffer-layer solution. The buffer-layer solution forms the buffer layer on the photoelectric transducing layer when the back electrode substrate is immersed in the buffer-layer solution. The second bath tank is for storing a window-layer solution. The window-layer solution forms the ZnO window layer on the buffer layer when the back electrode substrate is immersed in the window-layer solution. The first bath tank and the second bath tank are in an in-line arrangement.
