    Polyaniline micro-rods based heterojunction solar cell: Structural and photovoltaic properties
    (Amer Inst Physics, 2012) Sonmezoglu, Savas; Tas, Recep; Akin, Seckin; Can, Muzaffer
    The present paper reports the fabrication and photovoltaic characterization of pure and dodecyl benzene sulfonic acid (DBSA)-doped polyaniline (PAni) micro-rods polymer/n-Si heterojunction solar cells, and also the morphological and structural properties of pure and micro-rods PAni doping with DBSA. The device shows a strong photovoltaic behavior with a maximum open-circuit voltage V-oc of 0.83 V, a short-circuit current J(sc) of 14.72 mA cm(-2), fill factor FF of 0.54 resulting in an estimated device efficiency eta of 6.13% under simulated solar light with the intensity of 100 mW/cm(2). The results indicate that the Au/DBSA-doped PAni micro-rods/n-Si heterojunction structure might be promising for the solar cell applications. (C) 2012 American Institute of Physics.
