Abstract:
PURPOSE: A nanoparticle oxide solar cell, its preparation method, a solar cell module using the solar cell and a transparent electric window are provided, to minimize the space between solar cells of the module for minimizing the loss of power and maximizing the contact between cells. CONSTITUTION: The nanoparticle oxide solar cell comprises a primary conductive plate(21) where a negative electrode(22) region is formed in one side; a secondary conductive plate(21') where a positive electrode(23) region is formed in the other side; a binding/sealing means which binds the primary and secondary conductive plates so that a primary and secondary conductive plates face each other and the two regions where the positive or negative electrode is not formed are not overlapped, and seals the regions where the positive electrode and the negative electrode face each other; a primary conductive adhesive(28a) which is formed in the unoverlapped region of the primary conductive plate; and a secondary conductive adhesive(28b) which is formed in the unoverlapped region of the secondary conductive plate. Preferably the sealed region formed by the binding/sealing means contains an electrolyte.
