Proceedings for review of solar cell surfaces

A method for inspection of solar cellsurface for recognition of deposits of a contact material on a solar cellsubstrate, comprising the steps of: - applying (101) a reverse voltage to the solar cell(1); - selecting (103) an area on a surface (3) of the solar cell(1), is on the formation of contacts (5) are not provided by means of a contact material; - spectrally and / or temporally-resolved detection (105) of electromagnetic radiationwhich is emitted due to the applied reverse voltage of the selected area of the solar cellsurface (3); and - finding (107) of deposits (7) of the contact material by means of analyzing the detected electromagnetic radiation, wherein the electromagnetic radiationcomprises a lamp of locations on the solar cellsurface, where deposits of the contact material are present.
