Abstract

Method for filling with liquid a semi-manufactured product for a liquid-containing photovoltaic element, which semi-manufactured product comprises at least one plate-like work electrode and a plate-like counter-electrode adhered thereto by means of a vapour and liquid-tight peripheral edge, wherein between the work electrode, the counter-electrode and the peripheral edge a space is provided for receiving a liquid, comprising the steps of (i) providing said semi-manufactured product, (ii) arranging a filling opening as desired in the work electrode or the counter-electrode, (iii) placing the semi-manufactured product with the filling opening directed upward on a horizontally placed rotatable disc in a manner such that the filling opening extends round the rotation axis of the disc within a circle of a predetermined radius R, (iv) placing around the filling opening on the semi-manufactured product a holder with a flat underside and provided with an opening, wherein the opening has at least an internal diameter 2R and the outer diameter of the holder on its underside is smaller than the smallest surface area dimension of the semi-manufactured product, (v) introducing liquid into the holder and causing rotation of the disc with the semi-manufactured product and the holder placed thereon at a rotation speed and for a period such that the space in the semi-manufactured product is completely filled with liquid under the influence of centrifugal forces and the gravitational force acting on the liquid, and (vi) sealing the filling opening, and apparatus for performing this method.
