Enhanced efficiency of silicon micro-pyramids/poly(3,4-ethylenedioxythiophene):polystyrene sulfonate/gold nanoparticles hybrid solar cells

Improving the efficiency of n-Si/PEDOT:PSS hybrid solar cells by incorporating AuNP-decorated graphene oxide as a nanoadditive for conductive polymers

“…Energy could be stored in a confined surface plasmon mode using these antennas. 50,51 The trend of increasing and decreasing the conversion efficiency of solar cells is almost similar to the increase and decrease of conductivity of PEDOT:PSS/GO-AuNPs films. Furthermore, the presence of AuNPs in the hybrid solar cell will improve the optical absorption of the PEDOT:PSS/AuNPs resulted from the light-trapping effect of AuNPs at wavelengths below 500 nm.…”

“…Consequently, the external quantum efficiency (EQE) of the hybrid solar cell will be enhanced in the wavelength range from 300 to 600 nm as addressed in the previous work. 50,51 The dark J-V characteristic curve of the solar cell is shown in Fig. 5c.…”

“…The device that has a smaller leakage current will hold higher values of V OC , which will result in an increase in the efficiency. 50,51 Thus, the PEDOT:PSS/GO-AuNPs compound is a promising materials for hybrid solar cells to achieve high PCEs.…”

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

“…The increased EQE might have resulted from the light-trapping effect of AuNPs at wavelengths less than 500 nm and the increase in the optical absorption of the PEDOT:PSS/AuNPs, as discussed in the previous study. 25 Furthermore, the presence of AuNPs increased the roughness of the device surface, leading to an increase in EQE. 30 Fig.…”

“…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. 23–29 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.…”
