    • Site-independent light harvesting, followed by rapid dye-to-dye energy transfer, however, could conceivably allow injection to be funneled through a small number of dyes adsorbed at pinhole sites. Similarly, rapid dye-to-dye hole transfer could conceivably allow electron recombination to be mediated efficiently by a small number of dyes adsorbed at pinhole sites
