Abstract
Embodiments of the present invention describe a photovoltaic cell integrated into a display device. The photovoltaic cell is designed with an absorption spectrum that does not include a range of wavelengths corresponding to a particular color of visible light. Besides having the capability to harvest light, the photovoltaic cell can also function as a color filter and a photodetector.
Claims29
A display device comprising:
- a pixel;
- and
- a photovoltaic cell over the pixel to absorb light, the photovoltaic cell having a visible light absorption spectrum that does not include a range of wavelengths corresponding to a first color of visible light.
A display apparatus comprising;
- a display screen;
- a plurality of pixel units to transmit light to the display screen, each pixel unit comprising a first subpixel;
- and
- a plurality of photovoltaic units, each photovoltaic unit comprising:
- a first photovoltaic cell between the first subpixel and the display screen, wherein the first photovoltaic cell is to absorb ambient light transmitted through the display screen to generate electrical energy, and wherein the first photovoltaic cell is transparent to a first primary color of light.
2 more elements
A photovoltaic device comprising:
- a first photovoltaic cell comprising:
- a first electrode layer;
- a first absorption layer over the first electrode, wherein the first absorption layer is to absorb a first color;
- a second absorption layer over the first absorption layer, wherein the second absorption layer is to absorb a second color;
- and
- a second electrode layer over the second absorption layer.
