摘要

We study the performance of PCPDTBT:C_(71)-PCBM organic photovoltaics (OPVs) for three hole transporting layers (HTL); PEDOT:PSS, nickel oxide (NiO) and molybdenum trioxide (MoO_3). We show that devices fabricated with nickel oxide HTL demonstrate the highest power conversion efficiency and theoretical data using a transfer matrix model confirms that this is as a result of increased absorption in the active layer as well as a result of improved series resistance and improved matching of energy levels. Device degradation is studied and lifetime is highest for the NiO and MoO_3 based devices, proving that OPVs with this material system are less sensitive to the environmental effects of water, oxygen and irradiance.
