(US4697041-A)      Integrated solar cell consists of a laminate of a bottom electrode, a photosensitive semiconductor layer, and a top electrode and comprising series connected unit cells. At least the electrode layers are divided to form the cells, the series-connection being made by connecting a bottom electrode of a cell of neighbouring cells with a top electrode of another cell. At least the top electrode and/or semiconductor layer has a laser scribed groove in a designated pattern and there is an insulating strip between the top electrode and semiconductor layer and/or between the bottom electrode and the semiconductor layer along the pattern.    ADVANTAGE -   Improved structures of interconnection between unit cells of integrated solar cells. (15pp)    (DE3604894-C)      The integrated solar cell uses a laminate with a semiconductor layer (3) sandwiched between 2 electrode layers (2, 5) which are divided to define a series of individual cells, connected one after the other via electrical couplings between the lower electrode layer (2) of one cell and the upper electrode layer (5) of the adjacent cell. The upper electrode layer (5), or the semiconductor layer (3) is machined via a laser beam to obtain a pattern of grooves (6, 7) with an insulating strip (4a, 4b) extending along the line sof this pattern between the upper or lower electrode layer (5, 2) and the semiconductor layer (3).
