Abstract
  • Organic photovoltaics (OPVs) have the potential to provide clean, renewable energy. In this thesis work, solar devices were constructed by using an inverted architecture. Silicon naphthalocyanine (SiNc) and one of three phthalocyanine molecules (Pc1, Pc2, or Pc3) were separately added to the active layer of OPV solar cells in order to determine their impact on the performance and spectral response. Also, time-resolved microwave conductivity (TRMC) measurements were performed on thin films of P3HT:PC60BM with SiNc or one of three phthalocyanine molecules, neat P3HT with one of the small molecules, and neat PC60BM with a small molecule. The results from the TRMC experiments demonstrate that ternary blends showed characteristics of a three-phase morphology and it was possible to provide insight into the location of the molecules in the bulk heterojunction by analysis of the data. Therefore, TRMC has the potential to probe the morphology of different systems used for solar devices.
