“…Two further approaches for nanoparticle formation via chemical processes are spray pyrolysis and electrodeposition. In spray pyrolysis, both metallic [44] and dielectric nanoparticles [45] can be grown from precursor solutions that are nebulized and deposited onto a heated substrate. The nanoparticles form directly on the substrate, unifying nanoparticle growth and deposition in a single process step, yet with improved control over size and density.…”

“…Moreover, several groups used Au nanoparticles for the plasmonic enhancement, which can dramatically increase the cost. 24,26 In this work, a spray chemical vapor deposition method (spray-CVD) 27,28 was used for one step implementation of size and density controlled silver nanoparticles (Ag NPs) into UTPSC. 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.…”

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.

“…This low cost spray chemical vapour deposition (spray-CVD) method is adapted from the ILGAR ® process (ion layer gas reaction) and operates under atmospheric pressure. (Fischer et al, 2011;Liu et al, 2015) Trimethylphosphine (hexafluoroacetylacetonato) silver (Ag(hfacac)PMe 3 ) was used as precursor to form Ag NPs on fluorine-doped tin oxide coated glass substrates (FTO). By varying different deposition parameters, size and density controlled Ag NP films can be obtained.…”

Ag nanoparticles have attracted interest for plasmonic absorption enhancement of solar cells.For this purpose well-defined particle sizes and densities as well as very low deposition temperatures are required. Thus, we report here a new spray chemical vapour deposition method for producing Ag NP films with independent size and density control at substrate temperatures even below 100 °C which is much lower than for many other techniques. This method can be used on different substrates to deposit Ag NP films. It is a reproducible, low-cost process which uses Trimethylphosphine (hexafluoroacetylacetonato) silver as precursor in alcoholic solution. By systematic variation of deposition parameters and classic experiments, mechanisms of particle growth and of deposition processes as well as the low decomposition temperature of the precursor could be explained. Using the 3D finite element method, absorption spectra of selected samples were simulated which fitted well with the measured results. Hence, further applications of such Ag NP films for generating plasmonic near field can be predicted by the simulation.
