Abstract
A power supply including a luminescent solar concentrator (LSC) adapted for placement in an eye includes a base material transparent to visible light; and fluorescent particles doped within the base material. The fluorescent particles are capable of absorbing and reemitting light in the ultraviolet spectrum. A concentration of the fluorescent particles as a function of radius from an optical axis of the LSC is reduced in at least a portion of the base material outside of a pupil diameter. At least one photovoltaic cell is configured to receive the light in the ultraviolet spectrum trapped within the base material and to convert the trapped light into electricity.
