In an electrode substrate 1, the surface of a metal circuit layer 12 is covered and insulated by an insulating layer 14. In a photoelectric conversion element that uses this electrode substrate 1, the metal circuit layer is reliably shielded from an electrolyte solution or the like so that corrosion and leak current thereof is effectively prevented, and the photoelectric conversion efficiency can be improved. The insulating layer 14 is preferably made of a material that contains a glass component, and is particularly preferably formed by printing a paste that contains glass frit. The metal circuit layer 12 is preferably formed using a printing method.

The second electrode includes a first part supplying a first gas to a space between the first electrode and the second electrode, a plurality of second parts supplying a second gas to the space, a first supply path of the first gas connected to the first part, and a second supply path of the second gas connected to the second parts. The second supply path includes a main part with a first inlet of the second gas, and a branch part including a plurality of gas flow paths with a second inlet of the second gas. A number of the second parts are connected to each of the gas flow paths. The main part and the branch part are structured so that the second material gas does not flow into the second parts from the first inlet as a straight flow.
摘要:
A solar cell and photovoltaic power generation apparatus including a transparent electrically conductive film, a semiconductor provided on the transparent electrically conductive film, a conductive film opposing the semiconductor, and an electrolyte solution filled between the semiconductor and the conductive film. Metal ions, such as silver ions, may be dissolved in the electrolyte solution. When light is incident on the cell, the metal ions cause an oxidation-reduction reaction in the electrolyte solution and the cell is charged. When the open-circuit voltage decreases because the amount of incident light drops or light is blocked, the cell discharges to function as a secondary cell.
