Process for producing a photovoltaic element

摘要

A process for producing a stable photovoltaic element having an electrode structure comprising a collecting electrode and a metal bus bar which are connected to have an improved connection between them. Said electrode structure is formed by dotting an electrically conductive paste onto a metal wire as the collecting electrode such that a dotted electrically conductive paste has an elliptical form whose major axis and minor axis are respectively perpendicular to and parallel to a lengthwise direction of said metal wire, arranging the metal bus bar on said dotted electrically conductive paste, and heating the resultant while pressing it to cure the electrically conductive paste to form connection between the metal wire as the collecting electrode and the metal bus bar.
