In general, any improvement you made to the intensity of light falling on the cell would improve the output. I'd think that simply putting a better PV cell in would be a better upgrade…some of the cheap garden lights I see only have narrow little strips of PV material on the top. Lots of wasted surface area there.

Picture one of those cheap "solar garden lights" with a parabolic "thing" around the otherwise pitiful solar cells. (or perhaps in addition to a SC upgrade.) Will it improve things?
