Polyaniline micro-rods based heterojunction solar cell: Structural and photovoltaic properties

Abstract

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 Voc of 0.83 V, a short-circuit current Jsc of 14.72 mA cm−2, fill factor FF of 0.54 resulting in an estimated device efficiency η of 6.13% under simulated solar light with the intensity of 100 mW/cm2. The results indicate that the Au/DBSA-doped PAni micro-rods/n-Si heterojunction structure might be promising for the solar cell applications.

Investigation of structural and optoelectronic properties of annealed nickel phthalocyanine thin films

“…For certain advantages including ease of fabrication, thermal and chemical stability and insolubility in water, compatibility with flexible substrates and low-cost production processing, thin Pc films are commonly used in building electronic and optoelectronic devices such as organic solar cells [9,10], organic light emitting diodes (OLEDs) [11][12][13], field-effect transistors [14], optical recording [15], photodynamic therapy, non-linear optics [16], catalysis [17] and gas sensors [18]. It is known that the improvement of structural properties and photoconversion performance of PC-based devices rely mainly on understanding and controlling charge injection and charge transport processes [19][20][21].…”

Production of conductive bacterial cellulose-polyaniline membranes in the presence of metal salts

“…This is because the fibers bundled together with the polymerization of PANI. 17,54 Moreover, the structure of BC-PANI-Cu ( Figure 6(c)) was more organized than that of BC-PANI ( Figure 6(b)). This can be attributed to the increased degree of crystallinity of BC-PANI with the addition of the copper salt, thus facilitating the polymer chain arrangement.…”

Synthesis, characterization and physicochemical studies of copolymers of aniline and 3-nitroaniline

“…Polyaniline is popular owing to its ease of synthesis in aqueous media, reversible proton doping, highly tunable electrical conductivity, relative environmental stability and advanced optoelectronic properties [8][9][10]. Different micro-and nanostructures of PA have displayed versatile applications in diversified fields of organo-electronics [11][12][13][14][15].…”
