It was shown in the recent experiments that the hybrid organic/inorganic resonant structures can provide a flexible materials platform aimed at the design of novel light emitting devices. The applications of hybrid structures for photovoltaic solar cell can also be useful. We pay attention in this note that the resonant energy transfer in hybrid structure from the organic thin layer to the semiconductor nanostructures can drastically increase the intensity of the free carrier generation. To demonstrate this idea we use the results of recently published paper by Zhang et al., Nature Nanotechnology 2, 555 (2007), demonstrating the highly efficient resonance energy transfer from J-aggregates layer to semiconductor nanocrystals. It is known that the semiconductor nanocrystals with small energy gap represent a promising route to increased solar conversion in single--junction photovoltaic cells. We argue that the using of nanocrystals with small energy gap in the hybrid organic/inorganic structures similar to created by Zhang et al. can increase tens times the total intensity of carrier multiplication. The organic part in such hybrid structures will play a role of the peculiar organic concentrator of the light energy.
