The present invention is directed to solar cell strings () for photovoltaic modules comprising (i) a string of solar cells () facing each other in opposite polarity and shingled in string direction with or without partial overlap of solar cells (); (ii) at least one elongated electrically conducting interconnect () extending in string direction from one side of one solar cell to the opposite side of the next solar cell () for mechanically and electrically connecting the positive and negative electrodes of the shingled solar cells () in string direction on the alternating top and bottom sides of the solar cells, and (iii) at least two adhesives, optionally thermoadhesive foils () covering the at least one elongated interconnect () and at least part of the top or bottom side of each solar cell that comprises the elongated interconnect, with the proviso that (a) there is no horizontal gap between shingled solar cells, (b) the adhesives () do not contact each other, do not extend beyond one solar cell, do not extend into the optional partial overlap of solar cells (), and at least partially cover and mechanically fixate the at least one interconnect () to the solar cells ().

Solar cell string for use in a photovoltaic module

Disclosed is an interdigitated back contact photovoltaic device that includes a first patterned silicon layer situated on an intrinsic layer, and having the same type of doping as the one of the substrate. First charge collection portions are deposited on predetermined areas of the intrinsic layer, and include each an amorphous layer portion situated between the predetermined areas and the at least partially nano-crystalline layer portions. The amorphous layer portions have a larger width than the width of the nano-crystalline layer portions. On top if the first patterned silicon layer, a second nano-crystalline silicon layer is deposited that has a doping of a second type being the other of the p-type doping or the n-type doping with respect to the doping-type of the first patterned silicon layer.

Photovoltaic device and method for manufacturing the same

A capacitive-coupled parallel plate plasma enhanced chemical vapor deposition reactor includes a gas distribution unit that is integrated in an RF electrode and is formed with a gas outlet. The parallel plate reactor is configured so that layers with high thickness homogeneity and quality can be produced. The capacitively coupled parallel plate plasma enhanced vapor deposition reactor has gas distribution unit with a multiple-stage showerhead constructed in such a way that it provides an independent adjustment of gas distribution and gas emission profile of the gas distribution unit.
