Abstract
Solar cell wafers are fabricated, tested, and sorted into solar cell wafer stacks. A solar cell wafer stack includes a solar cell wafer with a front side that faces a front side of an adjacent solar cell wafer, and another solar cell wafer with a backside that directly contacts a backside of the solar cell wafer. A front side protector may be placed between front sides of adjacent solar cell wafers. The solar cell wafer stack includes end pieces on both ends, and is wrapped to hold and bundle the solar cell wafers, front side protectors, and end pieces together as a single unit. The solar cell wafer stack is boxed along with other solar cell wafer stacks, and then transported to another location where the solar cell wafers are assembled into solar cell modules.
Claims20
A method comprising:
- testing a plurality of solar cell wafers;
- after testing the plurality of solar cell wafers, stacking the plurality of solar wafers into a solar cell wafer stack, the plurality of solar cell wafers in the solar cell wafer stack being arranged such that a front side of a first solar cell wafer is facing toward a front side of an adjacent second solar cell wafer, and a backside of the first solar cell wafer is directly contacting a backside of an adjoining third solar cell wafer;
- and
- boxing the solar cell wafer stack along with other solar cell wafer stacks.
An article of manufacture comprising:
- a stack of solar cell wafers comprising a first solar cell wafer having a front side that faces a front side of a second solar cell wafer that is adjacent to the first solar cell wafer, a third solar cell wafer having a backside that directly contacts a backside of the first solar cell wafer, and a fourth solar cell wafer having a backside that directly contacts a backside of the second solar cell wafer.
A method of comprising:
- stacking a plurality of solar cell wafers into a solar cell wafer stack such that a front side of a first solar cell wafer faces a front side of a second solar cell wafer that is adjacent to the first solar cell wafer, a backside of a third solar cell directly contacts a backside of the first solar cell wafer, and a backside of a fourth solar cell directly contacts a backside of the second solar cell wafer;
- and
- wrapping the solar cell wafer stack.
