摘要： A method for producing a solar cell from a silicon wafer, including the following process steps: A) texturizing one side of the silicon substrate (1) for improving the absorption or removing saw damage on one side of the silicon substrate (1); B) generating an emitter area (2) on one side of the silicon substrate (1) by diffusing in a doping material for forming a pn transition; C) removing a glass layer which comprises the doping material; D) applying a masking layer (3) which is a dielectric layer; E) removing one part of the material of the silicon substrate (1); F) applying metal structures (5, 6) for electrically contacting the solar cell. It is significant that thermal oxidation is performed between the process steps E and F for forming an oxide layer (4) and that the masking layer (3) and the oxide layer (4) remain on the silicon substrate (1) in the subsequent process steps.

摘要： A metal grid contact and dielectric pattern on a layer requiring conductive contact in a photovoltaic device. The invention includes, in one aspect, forming a metal film; forming an etch resist over the metal film by, e.g., directly writing and in-situ curing the etch resist using, e.g., ink-jetting or screen-printing; etching the metal film leaving the resist pattern and a metal grid contact pattern under the etch resist intact; forming a dielectric layer over the etch resist; and removing the resist pattern and the dielectric over the etch resist, leaving a substantially co-planar metal grid contact and dielectric pattern. The metal grid contact pattern may form the front and/or back contact electrode of a solar cell; and the dielectric layer may be an optical reflection or antireflection layer. The layer requiring contact may be multifunctional providing its own passivation, such that passivation is substantially not required in the dielectric layer.

摘要： The present invention relates to rear-side contact solar cells and also solar cell modules manufactured therefrom, said modules having a special electrode structure, and also to a method for the production thereof. The electrodes, via which the current of the rear-side contact cell is tapped, are thereby separated by an insulating layer from the finger contacts which are in contact with the n- or p-semiconductor element of the solar cell through an insulating layer. The method makes possible a substantial simplification relative to the production methods described in the state of the art by means of spatial decoupling of the structuring of the electrodes from the solar cell.
