Abstract

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.
