摘要: Most of the high-efficiency organic photovoltaic devices (OPVs) reported to date have been fabricated based on concept a bulk heterojunction, where conjugated polymer (donor) and soluble fullerene (acceptor) form an interpenetrating network featuring large donor–acceptor interfacial area. In this chapter, we first introduce fundamentals OPVs then review recent progress related polymers. We discuss annealing approaches that used optimize morphologies photoactive layers, including thermal solvent annealing, describe engineering interfaces at contacts between blends metal electrodes. Next, outline two most common optical methods for improving light absorption efficiency OPVs: use spacers triggering surface plasmons. Finally, summarize development low-band-gap polymers long-wavelength photons from solar irradiation provide brief outlook future OPVs.
