NOVELTY - The method for electroplating a sunny side (2) of non-illuminated solar cells (1), which are made of silicon or other semiconductors, in electrolytic cells of continuous feed systems, immersion bath systems or cup-plates using a rectifier, comprises negatively polarizing the solar cell at its electrically conductive rear side (11) by an electrical wires and contacts through output voltage of the rectifier and positively polarizing an anode (6) in the electrolytic cell against sunny side to flow electroplating current (I) in blocking area of the solar cell when no bypass diode is integrated.    USE - Method for electroplating a sunny side of non-illuminated solar cells.    ADVANTAGE - The method is capable of effectively electroplating the sunny side of the non-illuminated solar cells with less energy consumption and less requirements required power densities and exposure times.    DETAILED DESCRIPTION - The method for electroplating a sunny side (2) of non-illuminated solar cells (1), which are made of silicon or other semiconductors, in electrolytic cells of continuous feed systems, immersion bath systems or cup-plates using a rectifier, comprises negatively polarizing the solar cell at its electrically conductive rear side (11) by an electrical wires and contacts through the output voltage of the rectifier and positively polarizing an anode (6) in the electrolytic cell against the sunny side to flow an electroplating current (I) in a blocking area of the solar cell when no bypass diode is integrated and to flow an electroplating current (I) in a passage area of the bypass diode when the bypass diode is integrated in the solar cell. The electric contact and the introduction of the electroplating current take place in the solar cell to be electroplated at the sunny side to the rear side, which is present inside of an electrolyte (12), and/or take place in the solar cell only at its rear side for electroplating the both sides of the solar cell. The electroplating current is fed into the solar cell to be electroplated using rotatable, clampable or slidable contacts. During electroplating both sides of the solar cell, two variable rectifiers supply the electroplating current into the solar cell. The solar cells are electroplated under the use of soluble or insoluble anode and by variable pulse rectifier. The parallel solar cells are fed with electroplating current by the rectifier over each power distribution resistance. For electrolytically etching the sunny side of the non-illuminated solar cells, the sunny side of the solar cells is electrically contacted only at the rear side and is connected with a positive pole of the rectifier, where the negative pole of the rectifier is connected with an electrode, so that the solar cell and/or the inner photodiode is operated in the passage area of the first quadrants. An INDEPENDENT CLAIM is included for a device for electroplating a sunny side of non-illuminated solar cells.
