ENERGY HARVESTING DEVICE with PREFABRICATED THIN FILM ENERGY ABSORPTION SHEETS AND ROLL-TO-SHEET AND ROLL-TO-ROLL FABRICATION THEREOF

摘要

An energy harvesting device includes prefabricated thin film energy absorption sheets that are each tuned to absorb electromagnetic energy of a corresponding wavelength. The energy harvesting device can include a prefabricated thin film converter sheet to convert the electromagnetic energy into electrical power. The energy harvesting device can include a prefabricated thin film battery sheet to store the electrical power. Each thin film energy absorption sheet can be fabricated using a roll-to-roll process. The energy harvesting device can be fabricated using a roll-to-sheet process from rolls of the thin film energy absorption sheets.

主权项

1. A roll-to-sheet method for fabricating energy harvesting devices comprising:
unrolling a plurality of prefabricated thin film sheets, including a plurality of prefabricated thin film energy absorption sheets, from a plurality of corresponding rolls of the prefabricated thin film sheets into which the prefabricated thin film sheets have been wound; laminating the thin film sheets together after unrolling; drilling a plurality of vias through the thin film sheets after lamination; filling the vias with a conductive material; and dividing the thin film sheets into the energy harvesting devices after drilling and filling the vias, wherein the thin film energy absorption sheets absorb electromagnetic energy.
