Abstract:
A method of producing a photovoltaic device, comprising the steps of forming a metal layer and/or a transparent and electroconductive layer by using a sputtering method comprising the steps of:forming a plurality of tunnel-shaped magnetic fluxes on a target;forming an electric field between the target and a belt-shaped substrate; andconveying the belt-shaped substrate while reciprocating the plurality of tunnel-shaped magnetic fluxes at least in the direction of conveying the belt-shaped substrate,wherein the speed v of conveying the substrate, the distance L in the direction of conveying the belt-shaped substrate between two adjacent points where the magnetic field of the plurality of tunnel-shaped magnetic fluxes and the electric field cross each other at a right angle, and the period T of a reciprocating motion of the plurality of tunnel-shaped magnetic fluxes are controlled so as to satisfy L/v=(n+1/2)T wherein n is z-1/16<n<z+1/16 and z is an integer equal to or greater than 0.
