This study is a follow up to our previously published manuscript on "improved power conversion efficiency in Perovskite solar cell using silver nanoparticles modified photoanode". Three more photoanodes were fabricated which are: Ag@ P 4 VP NPs mixed with perovskite layer (S2), Ag@P 4 VP NPs simultaneously mixed both in TiO 2 and perovskite films (S3) and P25 NP simultaneously mixed both in TiO 2 and perovskite absorber (S4) and their performances were investigated systematically. The performance, especially the photocurrent, and open circuit voltage of PSCs made of Ag@P 4 VP NPs were significantly affected. The champion device is S3, which shows enhancement in power conversion efficiency (PCE) from 3.80 to 9.05%, short circuit current density (Jsc) from 11.04 to 15.87 mA cm −2 , open circuit voltage (Voc) from 0.85 to 0.88 and fill factor (FF) from 0.41 to 0.65, which demonstrates ~ 2.38 times improvement in PCE over the control device (C). When Ag@P 4 VP NPs was mixed with TiO 2 , PCE of 5.69%, Jsc of 12.61 mA cm −2 , Voc of 0.88 V and FF of 0.51 were achieved, which shows ~ 1.50 times improvement over the performance of the reference cell. Also, when Ag@P 4 VP NPs was mixed with the perovskite layer, PCE of 8.08%, Jsc of 14.18 mA cm −2 , Voc of 0.89 V and FF of 0.64 were achieved, which shows ~ 2.13 times improvement over the performance of the pristine device. The addition of Ag@P 4 VP NPs enhanced exciton generation and dissociation, encouraging charge separation/transfer, as well as reducing quenching losses. For the hysteresis test, it was found that the devices with Ag@P 4 VP NPs have almost identical J-V curves with negligible hysteresis, which is attributed to the significant reduction of the trap density of the perovskite film when Ag@P 4 VP NPs is incorporated to fill the pores with high trapping rate. We however observed hysteretic behavior in devices C and S4, which makes it difficult to estimate the real PCE.

“…Silver nanoparticle-based titanium dioxide paste was prepared by mixing TiO 2 powder (1 g), ethylene glycol (1 mL), and silver nanoparticle (3 mL) [13] [14] [15]. The anode was prepared by subsequently administering TiO 2 paste via the doctor-blade method, using a glass rod and adhesive tape to form a 2 × 2 cm rectangle, on the conductive surface of the FTO glass [16]. The FTO glass was air dried for 10 min and then annealed at 450˚C for 30 min.…”

A plasmonic effect of silver nanoparticles (AgNPs) in dye-sensitized solar cells (DSSCs) is studied. In this investigation, the efficiency of dye-sensitized solar cells has been remarkably increased by infusion of synthesized silver nanoparticles into the TiO 2 photoanode. Rhodaminederivative RdS1 was synthesized by microwave-assisted condensation of hydrazide and 3-formylchromone. The synthesized silver nanoparticles were characterized with UV/Vis absorption spectroscopy and transmission electron microscopy. The interfacial charge transport phenomena of the dye-sensitized solar cell (DSSCs) are determined by electrochemical impedance spectroscopy and the corresponding efficiencies are calculated using current-voltage (I-V) curve. The solar cell photoanode with silver nanoparticles infused with RdS1 in titanium dioxide had the highest solar-to-electric power efficiency at 0.17%.

“…The intensity of the absorption peak increased with time and reflected increased formation of silver particles. This is due to the increasing in size of the nanoparticles by increasing the SILAR cycles as a result of coalescence of Ag nanoparticles at higher SILAR deposition cycles (Zong et al, 2014;Isah et al, 2016;Gharibshahi et al, 2017). Similarly, the main absorption peaks observed at 450 nm, 455 nm, 470 nm, 455 nm, and 500 nm for 5, 8, 11, 14 and 17 SILAR cycles are proportionate to a peculiar characteristics of the silver nanoparticles surface plasmon resonance band (Zong et al, 2014;Thiwawong et al, 2013).…”

Article InfoThis work reports the synthesized plasmonic silver nanoparticles (Ag-NPs)by SILAR (successive ionic layer adsorption and reaction)technique on glass substrates with 5, 8, 11, 14 and 17 SILAR cycles and effect on the optical properties of the thin films (TFs). The absorbance data of the as-synthesized Ag-NPs thin films were obtained using UVVis (Ultraviolet visible) spectroscopy at room temperature in the wavelength range of 250nmto 900nm. The transmittance, absorption coefficient, optical bandgap, refractive index and extinction coefficient were experimentally measured. The absorption peaks of(450, 455, 470, 455, 500) nm, and optical energy band gaps of (2.20, 2.16, 2.12, 2.11, 1.84) eV with absorption coefficient approximately 10 -12 cm -1 were identified for the SILAR cycles, which agree to a particular characteristics of the silver nanoparticles surface plasmon resonance band. The results showed a red shift from 450nm to 500nm by increasing the SILAR cycles from 5 to 17 cycles, which is attributed to coalescence of Ag nanoparticles at higher SILAR deposition cycles. An increase in the refractive index of the films from 1.55 to 2.51 observed, with approximate average value of 1.92, may be due to the optical properties of silver nanoparticles. This study revealed that Ag-NPs synthesized by SILAR technique gives good optical properties with excellent absorption bands in the visible region, which has potential applications in technology.
