Zusammenfassung: | A method for manufacturing two series-connected photovoltaic cells includes: forming an insulating substrate; forming a stack including; a first conductive layer formed on the substrate; a semiconductor layer comprising a first absorption layer and a second semiconductor layer forming a junction with the first absorption layer; and a second transparent conductive layer, formed on the absorption layer; forming an area dividing the stack into two cells series-connected by an electric path. The forming of said path comprises: forming a first trench all the way to the substrate; forming a second trench all the way to the first conductive layer; and depositing a conductive solution on the first trench and at last a portion of the second trench, so that the solution does not penetrate into the first trench all the way to the first conductive layer and penetrates into the second trench all the way to the first conductive layer. |
