“…2. A similar conclusion can be made through comparison of the results from Kato et al (1985) who used silver nitrate solution in ethanol to that of Pluym et al (1993a) who used aqueous silver nitrate; in both cases the Ag particles were solid. Systems that lie just below the line with slope = 0.16 (Fig.…”

ABSTRACT. This work is a review of the experimental results from the literature for single-component metal and simple metal-oxide particles. Criteria for correlating particle morphology, i.e., whether the particles are solid or hollow, with process parameters and material properties during spray pyrolysis are presented and compared with the data available in the literature. The materials were classified into two categories for which the precursor: (1) melts and (2) does not melt before chemical reaction takes place, and separate criteria were used for each category based on the work of Jayanthi et al. (1993) J. Aerosol Sci. 19:478. In systems where the precursor melts before chemical reaction occurs, eg., decomposition of nitrates of Mg, Al, Fe, Zn, Pb, Ni, Co, Pd, Mn, Cu, Sr, and Ag, the particle morphology is determined primarily by the densities and formula weights of the reactant and product compounds unless high temperature densification or puffingup of the particles due to gases evolved during the chemical reaction alter the morphology. In systems where the precursor undergoes nucleation to form a solid crust which does not melt before chemical reaction takes place, e.g., Ba(C,H,O,),, A12(S04), , Zr(C,H3O2),, and Zn(C2H3O2),, solubility and density of the precursor as well as the operating temperature are the main factors that affect the product particle morphology. Overall, particle morphologies predicted by the criteria were in agreement with experimental observations reported in the literature.

“…Tsai et al (2004) used ultrasonic spray pyrolysis and observed that uniform particles of 90 nm can be synthesized from smaller droplets whereas larger droplets generated porous particles. Pluym et al (1993) used three types of aerosol generators in synthesizing solid, spherical, micron-sized silver metal particles. It was observed that the effect of precursor concentration on the particle size was weak and mostly dependent on the aerosol droplet size.…”

Silver particles less than 20 nm in diameter were synthesized by pyrolysis of an ultrasonically atomized spray of highly dilute aqueous silver nitrate solution at temperatures above 650• C and below the melting point of silver. Feed solution concentration and ultrasound power applied to the atomizer were found to have a significant impact on the particle size of the silver nanoparticles. Average particle size was found to be controllable in the range of 20 nm to 300 nm by varying the solution concentration and the ultrasound power to the atomizer.

“…It has to be pointed out that the temperature of 110 C used to deposit Ag NPs was much lower than the reported work using spray pyrolysis to form Ag NPs. [29][30][31][32] This low temperature, size and density controlled Ag NPs deposition method has high potential for wide use in different applications. Optical properties of Ag NPs deposited on FTO substrates were studied by UV-Vis measurements.…”

“…The spray-CVD used here can easily be applied on large scale and the temperature used is much lower than that of the similar method reported in other work. [29][30][31][32] The thickness of the perovskite absorber layer used is around 140 nm, which is much thinner than the normal thickness ($300 nm or even thicker). By implementation of Ag NPs, a signicant enhancement of the short-circuit current density (J sc ) by 22.2% was obtained for the averaged performance of the solar cells, leading to a relative improvement of efficiency by 22.5%.…”

Enhancement of photocurrent in an ultra-thin perovskite solar cell by Ag nanoparticles deposited at low temperature

et al. 2017

Ultra-thin perovskite absorber layers have attracted increasing interest since they are suitable for application in semi-transparent perovskite and tandem solar cells. In this study, size and density controlled plasmonic silver nanoparticles are successfully incorporated into ultra-thin perovskite solar cells through a low temperature spray chemical vapor deposition method. Incorporation of Ag nanoparticles leads to a significant enhancement of 22.2% for the average short-circuit current density. This resulted in a relative improvement of 22.5% for the average power conversion efficiency. Characterization by surface photovoltage and photoluminescence provides evidence that the implemented silver nanoparticles can enhance the charge separation and the trapping of electrons into the TiO 2 layer at the CH 3 NH 3 PbI 3 /TiO 2 interface. The application of these silver nanoparticles therefore has promise to enhance the ultra-thin perovskite solar cells.
