Abstract
A flexible photovoltaically powered display, which may be utilized in a wide variety of display contexts including retail shelf systems, is described. The photovoltaic cell is preferably activated by ambient light (e.g., fluorescent or incandescent).
Claims28
A flexible display apparatus comprising:
- a flexible base;
- at least one flexible photovoltaic cell disposed upon the flexible base;
- and
- a display element disposed upon the flexible base and operably connected to the at least one flexible photovoltaic cell,
- wherein the at least one flexible photovoltaic cell comprises a photosensitized nanoparticle material and a polymeric linking that convalently interconnects the photosensitized nanoparticle material.
2 more elements
A method for forming a flexible display apparatus, the method comprising the steps of:
- providing a flexible base;
- disposing at least one flexible photovoltaic cell on the flexible base;
- and
- disposing a display element on the flexible base, such that the at least one flexible photovoltaic cell and the display element are in electrical communication,
- wherein the at least one flexible photovoltaic cell comprises a photosensitized nanoparticle material and a polymeric linking agent that covalently interconnects the photosensitized nanoparticle material.
