A solar cell including at least a first layer made of a semiconductor material for absorbing photons from light radiation and releasing charge carriers, and at least one conductive layer, overlapping the first layer, adapted to allow the light radiation to enter into the solar cell towards the first layer and to collect the charge carriers released by the first layer, the solar cell where the conductive layer includes at least three overlapped layers, including a transparent intermediate metal layer, made of metal, and two transparent oxide layers, made of a conductive oxide, where the two oxide layers are an inner oxide layer and an outer oxide layer surrounding the transparent intermediate metal layer to provide a low resistance path for the electrical charges and to maximize the amount of light radiation entering the solar cell. The embodiments also include a solar cells module including said solar cell.

Solar cell and solar cells module

The present invention concerns a bifacial solar cell () comprising a front side () and a back side (), said front and back sides () having a respective outer layer () made of transparent conductive oxide, on which is placed a respective metallization grid (), each metallization grid () comprising first collectors () running parallel to each other in a horizontal direction (x) of said solar cell () and second collectors () crossing said first collectors (), each second collector () comprising two vertical elements () and at least one horizontal element () every one or two first collectors () ororfirst collectors () connecting said two vertical elements (), said solar cell module being characterized in that said metallization grids () furtherly comprise at least one respective front or back area (), said front or back area () comprising said at least one horizontal element () and a portion of the underlying outer layer () made of transparent conductive oxide, so that a cell connector can be attached to said solar cell () by means of an electrically conductive adhesive deposited on said front or back area () without needing a physical barrier for said electrically conductive adhesive. The present invention also concerns a solar cell module and a method of manufacturing thereof.
