PURPOSE:To provide a large area thin film solar cell having a high photovoltaic conversion efficiency by a method when the resistance component of an electrode film is reduced while the decrease of the area ratio of the photovoltaic conversion region of the solar cell is minimized. CONSTITUTION:A first electrode film 2, a photovoltaic conversion semiconductor layer 3 and a second electrode layer 4 are built up in this order to form a photovoltaic conversion unit 5. A plurality of the photovoltaic conversion units 5 are arranged on an insulating substrate. The adjacent photovoltaic conversion units 5 are connected to each other in series with their end parts to compose a large area thin film solar cell. In this solar cell, contact grids 8, 8...8 are extended from the electrode films 2 (or 4) of the photovoltaic conversion units 5 into the next photovoltaic conversion unit 5 to be connected to the electrode films 4 (or 2) in series. |
