Abstract
In certain examples, methods and semiconductor structures are directed to an apparatus including a photon emitter such as an LED which operates over an emission wavelength range and a photo-voltaic device arranged relative to the photon emitter to provide index-matched optical coupling between the photo-voltaic device and the photon emitter for an emission wavelength range of the photon emitter.
Claims20
An apparatus comprising:
- a photon emitter;
- and
- a photo-voltaic device arranged relative to the photon emitter to provide index-matched optical coupling between the photo-voltaic device and the photon emitter for an emission wavelength range of the photon emitter.
An apparatus comprising:
- a photon emitter to operate over an emission wavelength range;
- a photo-voltaic device;
- and
- a spacer material, located between the photon emitter and the photo-voltaic device, to optically couple the photon emitter and one or more cells of the photo-voltaic device, wherein the spacer material is predominantly transparent in the emission wavelength range of the photon emitter.
1 more element
A method comprising:
- with a photon emitter and a photo-voltaic device being spaced relative to one another for providing index-matched optical coupling for an emission wavelength range of the photon emitter, between the photo-voltaic device and the photon emitter, causing the photon emitter to emit photons and the photo-voltaic device to respond by generating electric current.
