Abstract
A system may include a solar cell, a support defining an opening over the solar cell and comprising a retention feature, and an optical element disposed within the opening. The optical element may include a location feature engaged with the retention feature of the support. In some aspects, the optical element includes an upper surface to receive concentrated light and a lower surface through which light passes to the solar cell, and the location feature is disposed between the upper surface and the lower surface. The retention feature may be a lip defining the opening over the solar cell, and/or the location feature may consist of a notch defined by an edge of the optical element.
