Abstract:
A photovoltaic device is proposed comprising a silicon-based substrate ( 2 ) having a p-type or n-type doping, with an intrinsic buffer layer ( 4 ) situated on said substrate. A first silicon layer ( 6 ) of a first doping type is situated on predetermined regions ( 4 a ) of the intrinsic buffer layer. The first layer has interstices ( 5 ) between said predetermined regions ( 4 a ). The first silicon layer comprises at least partially a microcrystalline layer at its side away from the substrate. A microcrystalline silicon layer ( 8 ) of a second doping type is situated on said first silicon layer ( 6 ). A third silicon layer ( 10 ) of the second doping type is situated on said intrinsic buffer layer at the interstices, the third silicon layer being amorphous at its side facing said silicon-based substrate and comprising an at least partially microcrystalline layer portion to the side away from the intrinsic buffer layer.

Claim (Index 10):
A method for manufacturing a photovoltaic device, the method comprising:\n providing a silicon-based substrate having a first face, said silicon-based substrate having a p-type or n-type doping; depositing an intrinsic buffer layer on said first face; depositing a patterned first silicon layer on predetermined regions of said intrinsic buffer layer thereby leaving interstices between said predefined regions, said first silicon layer having a doping of a first type being one of p-type or n-type, said first silicon layer comprising an at least partially crystalline layer at its side away from said silicon-based substrate; simultaneously depositing a microcrystalline silicon layer which forms said second silicon layer on said first silicon layer, and said third silicon layer on said intrinsic buffer layer at said interstices, said second silicon layer having a doping of a second type being the other of p-type or n-type with respect to the doping of said first silicon layer, said third silicon layer being amorphous at least at its side facing said silicon-based substrate and being at least partially microcrystalline at its side away from said silicon-based substrate and having a doping of said second type, said second silicon layer and said third silicon layer constituting a single layer, defined as a tunnel layer, with the doping and the thickness of said tunnel layer being chosen so that the second silicon layer does not impede the charge collecting operation of the photovoltaic device; and depositing electrically conducting pads on said second silicon layer and said third silicon layer.
