In this work, the optical absorption enhancement of the organic (P3HT:PCBM) solar cells in the
presence of silver nanopyramids was investigated with a finite-difference time-domain method. The nanopyramids’ base lengths were changed from 40 to 160 nm. The results show for nanopyramids with a base length of 100 nm, the surface plasmon polariton as well as the effective forward scattering modes are excited effectively, which significantly contribute in enhancement of optical and electrical properties of organic solar cells. Due to the better light concentration in the absorption layer by nanopyramids, which are located under the ITO layer, this design is showed to be more influential in increasing the optical and electrical properties of the cells. The results show that for nanopyramids with a base length of 100 nm, the highest short-circuit current density enhancement are achieved.
