Effect of Au nanoparticles on the performance of hybrid solar cells

Enhanced power conversion efficiency of an n-Si/PEDOT:PSS hybrid solar cell using nanostructured silicon and gold nanoparticles

“… 27 Similarly, Sharma et al also reported a PCE of 8.2% for planar Si/PEDOT:PSS/AuNPs, which is higher than that of the device without AuNPs (7.3%). 29 The higher PCE for Si/PEDOT:PSS/AuNP hybrid solar cells was reported by Kim et al in which a PCE was measured to be 11.19% for the device containing AuNPs by the in situ method, which is approximately 19% higher compared to the device without AuNPs (9.42%). 30 Therefore, the incorporation of AuNPs acting as incident light antennas in PEDOT:PSS might improve the performance of hybrid solar cells.…”

“…The obtained results are in good agreement with other reports. [27][28][29][30] Lu et al reported that the PCE of the SiNHs/PEDOT:PSS hybrid solar cell containing AuNPs was determined to be 6.1%, which is an improvement of 27% compared to that of the solar cells without AuNPs. 27 Similarly, Sharma et al also reported a PCE of 8.2% for planar Si/ PEDOT:PSS/AuNPs, which is higher than that of the device without AuNPs (7.3%).…”

“…Furthermore, the increase in the electrical conductivity of PEDOT:PSS might be a factor resulting in a higher V oc compared to devices without AuNPs (0.514 V) and consequently a higher PCE. 27,29,30 In addition, the increase in PCE could originate from the reduction of the series resistance (R s ) of the device containing AuNPs (2.12 U cm 2 ) in comparison with the device without AuNPs and thus reduce the effective device resistance. 31 The decrease of the R s encourages the charge collection leading to an increase in the FF from 61 to 64%.…”

“…22 There are several proposed approaches to solve the above problems, such as using three-dimensional (3D) Si nanostructures (SiNW, SiNH, SiNPs), to improve the p-n junction area and the optical adsorption, and to add guest materials (AuNPs, Si quantum dots, graphene, graphene quantum dots) to improve the optoelectrical properties of the conductive polymer materials. [23][24][25][26][27][28][29] However, most of the published works only focused on using single Si nanostructures to enhance the PCE of the fabricated solar cells. There are no papers published to compare the performance among them.…”

“…AuNPs, AgNPs), which acts as plasmonic factors inside the organic layer, has also received considerable attention due to being a potential solution for enhancing the performance of the solar cells. [27][28][29][30][31][32][33] Thus, in this study, both Si surface modication and AuNP addition were used to improve the PCE of the hybrid solar cells resulting from the reduction in reectance and the increase in plasmonic effects. The chemical reduction approach was used to prepare AuNPs ($17 nm) that served as plasmonic enhancement factors.…”
