Effect of parameters such as thickness of ETM. Solar Cell Capacitance Simulator (SCAPS-1D) program was used to implement the model and simulation. In this research paper, a HTM-free perovskite solar cell (PSC) structure with Titanium (TiO2), methyl ammonium lead triiodide (CH3NH3PbI3) and platinum (pt) as electron transport material (ETM), photon harvester and metal back contact is proposed. The improvement is attributed to an increase in photocurrent density due to enhanced light harvesting by silver nanoparticles. Upon introducing 4 VP, a PCE of 5.69 %, Jsc of 12.61 mAcm-2 and Voc of 0.88 V were recorded, which improved the PCE ~ 39.4 % over that of the standard device. The power conversion efficiency (PCE), Jsc and Voc of the reference device shows a value of 3.80 %, 11.04 mAcm-2 and 0.85 V. The performance, especially the short circuit current density (Jsc), and open circuit voltage (Voc) of the PSC containing 4 VP NPs was significantly affected. The plasmonic enhancement effects are explored based on the combination of UV-visible absorption spectroscopy and Scanning Electron Microscope. The performance of Perovskite solar cell (PSC) by incorporating 4 VP NPs was investigated systematically. Metal nanoparticles have demonstrated outstanding properties in photovoltaic devices through introducing localized surface plasmon effects. When AgNPs is introduced on the m-TiO2, a PCE of 0.71 %, Jsc of 2.83 mAcm-2 and Voc of 0.46 V were obtained which which results to increase in power conversion efficiency (PCE) from 0.36 % to 0.71 %, demonstrating ~1.97 time’s enhancement, compared with the reference device without the metal NPs. Upon introduction of AgNPs on the c-TiO2, a PCE of 0.64 %, Jsc of 2.53 mAcm-2 and Voc of 0.46 V were recorded, which improved the PCE ~ 63.90 % over that of the prestine device. The power conversion efficiency (PCE), Jsc and Voc of the reference device shows a value of 0.36 %, 1.89 mAcm-2 and 0.45 V. In this work the systematic design and formation of plasmonic dye sensitized solar cells (DSSCs) by integrating Ag NPs nanoparticles (NPs) in two distinct configurations on the c-TiO2 and on m-TiO2 were reported. Placing AgNPs at different position will produce a variety of. When noble materials such as Ag, Au or Cu are added into the titania (compact or mesoporous) structure of the sensitized solar cell, the plasmonic effect of such materials will result to an improved performance of the device. Surface plasmon resonance is the effect of electron oscillation in a structure stimulated by incident light. We however observed hysteretic behavior in devices C and S4, which makes it difficult to estimate the real PCE. For the hysteresis test, it was found that the devices with 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 4 VP NPs is incorporated to fill the pores with high trapping rate. The addition of 4 VP NPs enhanced exciton generation and dissociation, encouraging charge separation/transfer, as well as reducing quenching losses. Also, when 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. When 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. 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). The performance, especially the photocurrent, and open circuit voltage of PSCs made of 4 VP NPs were significantly affected. and perovskite absorber (S4) and their performances were investigated systematically. Three more photoanodes were fabricated which are: P 4 VP NPs mixed with perovskite layer (S2), 4 VP NPs simultaneously mixed both in TiO 2 and perovskite films (S3) and P25 NP simultaneously mixed both in TiO 2. 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".
