Abstract
An apparatus and a method for its fabrication. The device may include a bifacial solar cell comprising a partially-transparent first surface and a partially-transparent second surface opposite the first surface, and an optical element comprising a first partially-transparent dielectric portion in contact with the first surface and the second surface. The optical element may be configured to receive light, to direct a first portion of the received light to the first surface, and to direct a second portion of the received light to the second surface.

An apparatus comprising:
- a solar cell comprising:
- a partially-transparent first surface;
- a partially-transparent second surface;
- a first p-n junction between the first surface and the second surface;
- a second p-n junction between the first surface and the second surface;
- and
- a third p-n junction between the first surface and the second surface,
- wherein a first bandgap associated with the first p-n junction is greater than a second bandgap associated with the second p-n junction, and
- wherein a third bandgap associated with the third p-n junction is greater than the second bandgap associated with the second p-n junction;
- and
- an optical element comprising a first partially-transparent dielectric portion in direct thermal contact with the first surface and the second surface,
- wherein the optical element is configured to receive light, to direct a first portion of the received light to the first surface, and to direct a second portion of the received light to the second surface.
