“…Metallic nanoparticles have been integrated to minimally enhance the efficiency of DSSCs, [14,15], also in Si base solar cells [16] and organic photovoltaic (OPV) cells [17][18][19][20]. Recently, noble metals have also been utilized to significantly improve the PCE of PSCs.…”

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.

“…One of the most important events of 1991 was the report on a new low-cost chemical solar cell by the successful combination of nanostructured electrodes and efficient chargeinjecting dye technology, known as dye-sensitised solar cell (DSSC) or Grätzel cell, which belongs to the third generation of efficient and inexpensive photovoltaic cells [1]. Besides Perovskite and tandem solar cells, DSSCs are considered among photovoltaic (PV) devices with the most potential.…”

“…The introduction of metallic nanoparticles (NPs) in appropriate places inside the active layer to confine visible light could provide superior performance due to improved absorption in the organic semiconductor film and enhance photocurrent generation via the effect of LSPR [1,33]. Metal NPs with sharp edges are highly desired due to the high electronic conductivity and their applications as interconnections in the bottom-up self-assembly approach towards future nanodevices.…”

Plasmon-assisted energy conversion in dye-sensitised solar cells (DSSCs) has been achieved by applying gold (Au) nanoparticles (NPs) inside Titania (TiO2) photoanodes. Gold nanoparticles (GNPs) were introduced into DSSCs to further enhance their power conversion efficiency (PCE). In this research work, an effort has been made to enhance the optical absorption and improve the performance of DSSCs. By utilising finite-difference time-domain (FDTD) software, GNPs with radii of 15, 25, 35, 45, 55, 65, 75 and 85 nm were produced and introduced into the TiO2 photoanode. The optimum radius for the optical absorption enhancement was found to be 85 nm because the effect of plasmon coupling is more significant for metal nanoparticle sizes > 60 nm. The effect of various sizes of GNPs on light scattering has also been presented in this study. Moreover, the investigation has focused on the role of incident angle of light source on the absorption in TiO2 films. It was found that the optimum incident angle for the enhancement of broadband optical absorption in the wavelength range of 450–800 nm is 70°.
