PURPOSE:To obtain a photoelectric converter with very little of output lowering in a cycle test of temperature-humidity under light irradiation by using fine powdered particles having water repellency as a conductive member serving as an electricity collecting electrode bound together with a conductive filler. CONSTITUTION:For an electricity collection electrode 104 of a photovoltaic element, a conductive paste prepared by uniformly mixing fine powder having water repellency, a conductive filler, and a binder with a three-roller is applied to form a pattern using a screen printing machine and a dispenser, and is heat- treated to form a conductive member. A material with a good water repellency is concretely a material which exhibit a numerical value of 35 or less when measured by a surface tension meter. Hereby, water is prevented from entering the electricity collection electrode and a contact property between the electricity collection electrode and a conductive layer located below the former is prevented from being lowered. Hereby, there is suppressed an appearance of a solar cell module which lowers its output in a temperature-humidity cycle test under light irradiation. |
