Abstract

2-(2,3-Dihydro-1,5-dimethyl-3-oxo-2-phenyl-1H-pyrazol-4-ylimino)-2-(4-nitrophenyl) acetonitrile (DOPNA) is an organic compound; it has been synthesized and examined as a photovoltaic material in thin-film form grown on single crystal of p-type silicon wafer substrate (p-Si). A polycrystalline structure has been formed in as-synthesized powder. Nano-crystallite grains are formed in the as-deposited film. The dark current–voltage (I–V) characteristics of Au/p-DOPNA/p-Si/Al heterojunction diode measured at different temperatures ranging from 298 to 423 K have been investigated. The operating conduction mechanisms, series and shunt resistances, rectification ratio, ideality factor and potential barrier height were determined. The capacitance–voltage (C–V) measurements of the device were performed in dark condition and analyzed to determine carrier concentration and built-in potential. Solar cell parameters were also evaluated and the power conversion efficiency was estimated as 5.74%.
