Hybrid Solar Cells with Outstanding Short-Circuit Currents Based on a Room Temperature Soft-Chemical Strategy: The Case of P3HT:Ag₂S

Abstract

P3HT:Ag(2)S hybrid solar cells with broad absorption from the UV to NIR band were directly fabricated on ITO glass by using a room temperature, low energy consumption, and low-cost soft-chemical strategy. The resulting Ag(2)S nanosheet arrays facilitate the construction of a perfect percolation structure with organic P3HT to form ordered bulk heterojunctions (BHJ); without interface modification, the assembled P3HT:Ag(2)S device exhibits outstanding short-circuit current densities (J(sc)) around 20 mA cm(-2). At the current stage, the optimized device exhibited a power conversion efficiency of 2.04%.

“…Ag 2 S, a compound semiconductor, appears in group I-VI with band gap [1] energy between 1.0 and 2.0 eV, is a favorable material in case of photovoltaic applications [4] due to its absorption mostly in the visible region. Several methods are available for the synthesis of shape and size controlled silver sulphide nanoparticles (NPs) using different stabilizing and protecting agents like polymers/ organic molecules.…”

“…With well controlled size and shape, Ag 2 S nanoparticles have great impact on emerging applications as they show diverse, fine and individual properties depending on their shape and size. Among different techniques of silver sulphide NP preparation [1][2][3][4][5][6] like, chemical bath deposition, spray pyrolysis, successive ionic layer absorbance and reaction, thermal evaporation, sol-gel reduction, chemical deposition; we have opted an in situ chemical reduction pathway due to its low cost, easily controllable and large scale production facilities. Depending upon the preparation technique, silver sulphide nanoparticles can show different shapes and sizes, which lead to diversified optical and electronic/electrical properties [1][2][3][4][5][6].…”

Making a complex of the precursor metal ion (here Ag + ) by a large organic molecule may result in some specific shape of the product semiconductor, as such large molecules can also act as the structure orienting or caging agents.…”

IntroductionSilver sulphide (Ag 2 S) nanoparticles have received great attentions due to its fascinating and exceptional properties [1][2][3][4][5][6] as well as numerous applications in different fields of modern science and technology since last couple of decades. Ag 2 S, a compound semiconductor, appears in group I-VI with band gap [1] energy between 1.0 and 2.0 eV, is a favorable material in case of photovoltaic applications [4] due to its absorption mostly in the visible region.
