We report the observation of photocurrent in silicon nanowires induced by nonradiative resonant energy transfer (NRET) from adjacent layers of lead sulfide nanocrystal quantum dots using time-resolved photocurrent measurements. This demonstration supports the feasibility of a new solar cell paradigm (Lu, S.; Madhukar, A. Nano Lett. 2007, 7, 3443-3451) that exploits NRET between efficient photon absorbers and adjacent nanowire/quantum well high-mobility charge transport channels and could offer a viable alternative to the limitations of carrier transport and collection faced by excitonic solar cells.
