Abstract
A photovoltaic module can be produced by suspending a photovoltaic cell with a front side of the photovoltaic cell facing upward, positioning a backsheet and a first encapsulant layer underneath the suspended photovoltaic cell, lowering the suspended photovoltaic cell into contact with the first encapsulant layer wherein a back side of the photovoltaic cell contacts the first encapsulant layer, applying a second encapsulant layer over at least the front side of the photovoltaic cell, positioning a front transparency onto the second encapsulant layer, and curing the first encapsulant layer and the second encapsulant layer.
Claims20
A process for producing a photovoltaic module comprising:
- suspending a photovoltaic cell matrix comprising a plurality of electrically interconnected photovoltaic cells, wherein front sides of the photovoltaic cells face upward when suspended;
- positioning a backsheet and a first encapsulant layer underneath the suspended photovoltaic cell matrix;
- lowering the suspended photovoltaic cell matrix into contact with the first encapsulant layer, wherein back sides of the photovoltaic cells contact the first encapsulant layer;
- applying a second encapsulant layer over at least the front sides of the photovoltaic cells and electrical interconnections;
- positioning a front transparency onto the second encapsulant layer;
- and
- curing the first encapsulant layer and the second encapsulant layer.
