A system may include a substrate, and a solar cell including a top side and a bottom side, the top side having an active area and the bottom side coupled to the substrate. A frame may be coupled to the substrate, the frame defining an upper opening above the active area and a lower opening above the active area and between the active area and the upper opening. The lower opening may be smaller than the upper opening in at least one dimension, and an optical element may be disposed within the upper opening.In some aspects, the lower opening is defined by a portion of the frame extending substantially parallel to the top side of the solar cell. In some aspects, the frame includes a first wall and a second wall opposing the first wall, an upper portion of the first wall is substantially parallel to an upper portion of the second wall, a lower portion of the first wall forms a first obtuse angle with the upper portion of the first wall, and a portion of the lower portion of the first wall defines a first side of the lower opening.
