Abstract: A system for stabilizing and/or improving an efficiency of a solar cell having a front-side front contact and a rear-side rear contact. The system includes: an illumination unit that is designed to locally illuminate the solar cell; a voltage source having two contacting apparatuses, wherein one contacting apparatus is designed to be connected to the front contact of the solar cell, and the other contacting apparatus is designed to be connected to the rear contact of the solar cell in such a way that a current flow is induced in the reverse direction of the solar cell. The system also includes a heating apparatus which is designed and configured to heat the solar cell during a current flow induced in the reverse direction.

Abstract: A method for producing a solar cell, including the following steps: a) providing a substrate having a front side and a back side in a deposition apparatus, and b) coating the substrate in situ with two layers, including b1) oxidizing, by exposing the substrate to an oxygen-containing gas and a first plasma, to create an oxide layer and b2) subsequently depositing a silicon layer or SiC layer by exposure to a gas containing silicon, an optional gas containing carbon and a second plasma, wherein step b) is carried out under vacuum in the deposition apparatus and the vacuum is maintained continuously during step b).

Abstract: The invention relates to a method for stabilizing a photovoltaic silicon solar cell, including a regeneration step in which a semiconductor substrate of the solar cell which are heated to at least 50° C. is injected with charge carriers. The invention is characterized in that a degradation step is carried out before the regeneration step, wherein the solar cell is subjected to radiation, in particular laser radiation, having an illumination intensity of at least 5.000 W/m2 and the solar cell is simultaneously cooled. The invention also relates to a device for stabilizing a photovoltaic silicon solar cell.
