Increasing the efficiency of organic solar cells using plasmonic nanoparticles

Numerical simulations show that the introduction of aluminum nanoparticles into one layer of a bulk-heterojunction organic solar cell leads to an increase in the rate of exciton generation in the active layer of the cell. According to calculations of the optical absorption in the cell, which have been performed in the effective refractive index approximation using the Maxwell–Garnet model, a maximum relative increase in the rate of exciton generation due to plasmonic nanoparticles is about 4%.
