Abstract:
The present disclosure provides a process. In an embodiment, the process includes providing an aqueous pigment-polyolefin dispersion (P-P dispersion) and applying a grid-pattern of the aqueous P-P dispersion onto a rear encapsulant film. The process includes drying the grid-pattern into a grid layer to form a gridded rear encapsulant film. The process includes placing a plurality of photovoltaic cells and a front encapsulant film onto the gridded rear encapsulant film to form a stack, and laminating the stack to form a reflective photovoltaic (PV) module. The present disclosure also provides a reflective photovoltaic module produced by the process.
