  We predict the enhanced light harvesting of a protein-pigment complex when
assembled to a quantum dot (QD) antenna. Our prototypical nanoassembly setup is
composed of a Fenna-Mattews-Olson system hosting 8 Bacteriochlorophyll (BChl) a
dyes, and a near-infrared emitting CdSe$_x$Te$_{(1-x)}$/ZnS alloy-core/shell
nanocrystal. BChl a has two wide windows of poor absorption in the green and
orange-red bands, precisely where most of the sunlight energy lies. The
selected QD is able to collect sunlight efficiently in a broader band and
funnel its energy by a (non-radiative) F\"orster resonance energy transfer
mechanism to the dyes embedded in the protein. By virtue of the coupling
between the QD and the dyes, the nanoassembly absorption is dramatically
improved in the poor absorption window of the BChl a.
