Abstract
A solar cell includes a first processed optically transparent (transparent) substrate and a second processed transparent substrate, wherein at least one of the first processed transparent substrate and second processed transparent substrate includes at least one electrode thereon. At least one solar absorber material substrate having a first side and a second side is between the first and second processed transparent substrates. The solar absorber material substrate is bonded by an adhesiveless bonded interface on both the first side and the second side to the first and second processed transparent substrates.
Claims11
A solar cell, comprising:
- a first glass substrate;
- at least a first electrode under said first glass substrate;
- a first intrinsic silicon layer under said first electrode, on an opposite side of said first electrode relative to said first substrate;
- a p-doped silicon layer on said first intrinsic silicon layer;
- a second glass substrate;
- at least a second electrode over the second glass substrate;
- a second intrinsic silicon layer over said second electrode on an opposite side of said second electrode relative to said second glass substrate;
- a n-doped silicon layer on said second intrinsic silicon layer;
- and
- at least one solar absorber material substrate having a first side and a second side,
- wherein said first side of said solar absorber material substrate is directly bonded to said first intrinsic silicon layer by a first direct adhesiveless bond forming a first adhesiveless bonded interface, and
- wherein said second side of said solar absorber material substrate is directly bonded to said second intrinsic silicon layer by a second direct adhesiveless bond forming a second adhesiveless bonded interface, where both said first and second direct adhesiveless bonds are achieved solely by physical forces.
A solar module, comprising:
- a first glass substrate;
- at least a first electrode under said first glass substrate;
- a first intrinsic silicon layer under said first electrode on an opposite side of said first electrode relative to said first glass substrate;
- a p-doped silicon layer on said first intrinsic silicon layer;
- a second glass substrate;
- at least a second electrode over the second glass substrate;
- a second intrinsic silicon layer over said second electrode, on an opposite side of said second electrode relative to said second glass substrate;
- a n-doped silicon layer;
- and
- a plurality of solar absorber material substrates each having a first side and a second side directly bonded to said first and said second intrinsic silicon layer, respectively, by a direct adhesiveless bond to provide a plurality of solar cells hooked in series via said network of interconnecting electrodes, wherein the direct adhesiveless bond is achieved solely by physical forces.
