## Description

- description: "Pencil-shaped silicon nanowires (SiNPs) were utilized in Schottky
    junction solar cells covered by sub-stoichiometric vanadium dioxide (VO2-x) to
    work as a hole injection layer. The asymmetry of nanopencils is responsible for
    their many useful properties, such as their ability to absorb and trap light over
    a wide spectrum. Dark current-voltage (I–V) curves for an Ag/VO2-x/SiNPs/Ti/Ag
    Schottky junction device were measured and analyzed across a temperature range
    of 298 – 358 K. The junction parameters were calculated in terms of thermionic
    emission theory at different temperatures from the (I–V) curves, including the
    ideality factor (n) and the barrier height ( φb), and were found to be 1.73 and
    0.78 eV, respectively, at room temperature. In the forward bias regime, we found
    that thermionic emissions dominate at low voltages (V  ≤ 0.12 V), space-charge-limited
    current controlled by a single trap state dominates at middle voltages (0.12  <
    V  < 0.3 V), and space-charge-limited current regulated by a distribution of trap
    levels dominates at high voltages (V  ≥ 0.3 V). The (C–V) measurements were used
    to calculate the built-in potential, which \r\nwas discovered to be 0.62 eV. Unless
    encapsulation is provided, PEDOT:PSS/SiNPs hybrid solar cells rapidly degrade
    under ambient conditions, whereas VO2-x/SiNPs solar cells are far more stable. "
