Recent efforts on quantum dot based intermediate band solar cell in GaAs are presented. Near record conversion efficiency for an intermediate band GaAs solar cell is measured, but this conversion efficiency is still lower than the one obtained for bulk GaAs. External quantum efficiency measurements shed some light on the reasons for getting a lower efficiency in intermediate band solar cells. A discussion of other works in this area is presented and new promising directions are defined.
