Abstract
An integrated energy harvesting and storage device (IEHSD) includes a solar cell (SC) including an active layer between an optically transparent top electrode and a bottom electrode, and an energy storage device (SD) secured below the solar cell including a separator between a first electrode and a second electrode. The bottom electrode and the first or second electrode are electrically common with one another and are within a distance of ≤300 μm from one another.
Claims17
An integrated energy harvesting and storage device (IEHSD), comprising:
- a solar cell (SC) including an active layer between an optically transparent top electrode and a bottom electrode;
- an energy storage device (SD) secured below the SC including a separator between a first electrode and a second electrode,
- wherein the bottom electrode and one of the first or the second electrode are electrically common, and wherein the bottom electrode is formed from a first side of a single metal material comprising a copper ribbon and the one of the first or second electrode is formed from a second side of the single metal material opposite the first side, the second side of the single metal material comprising copper hydroxide nanotubes and the first side of the single metal material being absent copper hydroxide nanotubes;
- and
- a connection between the optically transparent top electrode and the other of the first electrode and the second electrode for photo generated carriers generated by the SC to flow to and charge the SD.

A woven integrated energy harvesting and storage device (IEHSD), comprising:
- a solar cell (SC) including a plurality of SC filaments each including an active layer between an optically transparent top electrode and a bottom electrode that are aligned with one another;
- an energy storage device (SD) comprising a plurality of SD filaments each including a separator between a first electrode and a second electrode secured below the SC filaments to provide a plurality of stacked SC/SD filaments, wherein the plurality of SD filaments and the plurality of SC filaments share an electrically common electrode;
- a yarn material that is separate from the plurality of SC filaments and the plurality of SD filaments, the yarn material comprising first vertical yarns oriented in a vertical direction and second horizontal yarns oriented in a horizontal direction, wherein the first vertical yarns and the second horizontal yarns are interlaced together to provide a fabric, the fabric interlocking ones of the plurality of stacked SC/SD filaments together by crossing over and under adjacent ones of the plurality of stacked SC/SD filaments,
- wherein the electrically common electrode comprises the bottom electrode and one of the first or the second electrode, and wherein the bottom electrode is formed from a first side of a single metal material comprising a copper ribbon and the one of the first or second electrode is formed from a second side of the single metal material opposite the first side, the second side of the single metal material comprising copper hydroxide nanotubes and the first side of the single metal material being absent copper hydroxide nanotubes;
- and
- a connection between the optically transparent top electrode and the other of the first electrode and the second electrode for photo generated carriers generated by the SC to flow to and charge the SD.
