摘要： The present invention concerns a bifacial solar cell (1) comprising a front side (10) and a back side (20), said front and back sides (10, 20) having a respective outer layer (34) made of transparent conductive oxide, on which is placed a respective metallization grid (11, 21), each metallization grid (11, 21) comprising first collectors (111, 211) running parallel to each other in a horizontal direction (x) of said solar cell (1) and second collectors (112, 212) crossing said first collectors (111, 211), each second collector (112, 212) comprising two vertical elements (112a, 112b, 212a, 212b) and at least one horizontal element (112c, 212c) every one or two first collectors (111) or 3 or 6 first collectors (211) connecting said two vertical elements (112a, 112b, 212a, 212b), said solar cell module being characterized in that said metallization grids (11, 21) furtherly comprise at least one respective front or back area (113, 213), said front or back area (113, 213) comprising said at least one horizontal element (112c, 212c) and a portion of the underlying outer layer (34) made of transparent conductive oxide, so that a cell connector can be attached to said solar cell (1) by means of an electrically conductive adhesive deposited on said front or back area (113, 213) 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.

摘要： A solar cell apparatus 100 and a method for forming said solar cell apparatus 100, comprising a substrate 101, a n-type transparent conductive oxide (TCO) layer 102 deposited atop said substrate 101, a p-i-n structure 200 that includes a p-type layer 103, an i-type layer 104, a n-type layer 105, a metal back layer 106 deposited atop said n-type layer 105 of the p-i-n structure 200. The n-type layer 105 comprises n-type donors 115 including phosphorus atoms. The n-type donors 115 include oxygen atoms at an atomic concentration comprised between 5% and 25% of the overall atomic composition of the n-type layer 105.

摘要： In multijunction photovoltaic cells, such as for example tandem solar cells having a top sub-cell and a crystalline silicon based bottom sub-cell, efficiency of conversion of solar energy into electrical energy is limited mainly by the junction between a top sub-cell and a bottom sub-cell of the multijunction photovoltaic cell. A multijunction photovoltaic cell of this disclosure at least partially overcomes this drawback because it has an intermediate layer of silicon nitride deposited in a conformal manner with a thickness of between 1 and 10 nm so as to define a P-N tunnel junction between the top sub-cell and the bottom sub-cell. A related fabrication process is also disclosed.

摘要： A tandem photovoltaic structure including, from the rear face to the front face: a first solar cell—with a silicon heterojunction: a first layer of a first conductivity type made of amorphous silicon and a substrate of doped crystalline silicon disposed between two layers of intrinsic amorphous silicon, a recombination zone comprising a layer of nanocrystalline or monocrystalline silicon of the second conductivity type, a second solar cell comprising an active layer made of a perovskite material and a second layer of a second conductivity type. The recombination zone further includes a layer of the first conductivity type in contact with the active layer of the second cell or a layer of nanocrystalline or monocrystalline silicon of the first conductivity type in contact with the active layer of the second solar cell.
