In this work, a silicon nanowire solar cell for efficient light harvesting in the visible and near-infrared regions is introduced. In this structure, the silicon nanowires (SiNWs) are coated with a graphene layer and plasmonic nanoparticles are distributed on the top surface of the silicon substrate layer. The proposed structure is simulated using the finite difference time domain (FDTD) method to determine the performance of the solar cell by calculating the open-circuit voltage, fill factor, short-circuit current density, and power conversion efficiency. The absorbed light energy is compared for different nanoparticle materials, namely Au, Ag, Al, and Cu, and Au NPs give the best performance. Different values of the radius of the Au NP are simulated, namely 30, 40, 50, and 60 nm, to determine the optimum radius, and the effect of excess carrier concentration on the solar cell performance is also tested. The obtained open-circuit voltage is 0.63 V, fill factor is 0.73, short-circuit current density is 41.7 mA/cm2, and power conversion efficiency is 19.0%. The proposed SiNW solar cell improves the overall efficiency by almost 60%. Furthermore, the effects of the NW length and distance between NWs are also studied in this work. Finally, the distribution of the optical power in different layers along the solar cell and for different solar cell structures is also illustrated in this paper.

“…Owing to the visible light reflection characteristics of silicon nanowires (Si-NWs), combinatorial pyramid-nanowire Si substrates (denoted as Si-PNWs) offer several advantages in solar cells applications. The contact area between PEDOT:PSS and the Si substrate interface is increased, the high surface topography of villiform can significantly enhance the absorption of sunlight [ 11 , 12 , 13 , 14 , 15 , 16 , 17 ]. It was demonstrated that the pyramid form influenced incident light reflection and heterojunction interface properties [ 11 , 12 , 18 , 19 ].…”

Reducing the surface reflectivity of silicon substrates is essential for preparing high-performance Si-based solar cells. We synthesized pyramid-nanowire-structured Si (Si-PNWs) anti-reflection substrates, which have excellent light-trapping ability (<4% reflectance). Furthermore, diethyl phthalate (DEP), a water-insoluble phthalic acid ester, was applied to optimize the Si-PNWs/PEDOT:PSS interface; the photoelectric conversion efficiency of heterojunction solar cells was shown to increase from 9.82% to 13.48%. We performed a detailed examination of the shape and optical characteristics of Si-PNWs, as well as associated photoelectric performance tests, to investigate the origin of performance improvements in Si-PNWs/PEDOT:PSS heterojunction solar cells (HSCs).

“…Organic/Si hybrid solar cells have attracted increasing attention in recent years because of the facile deposition process of an organic layer, such as low temperature and cost-effectiveness. − A typical structure of the organic/Si hybrid solar cells is Ag grid/poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS)/n-Si/Al, where PEDOT:PSS is used as a hole transportation layer as well as a passivation layer and Al is used as a cathode to collect electrons. Though attractive progress has been made, the efficiency of the organic/Si hybrid solar cells still needs to be improved to meet the requirements of commercialization.…”

The contact quality between Si and the rear electrode and the passivation of Si play crucial roles in efficient organic/Si hybrid solar cells, especially for the open-circuit voltage (V OC ). Herein, we reported a dual bilayer structure to synergistically improve both rear contact quality and passivation of Si to enhance the performance of organic/planar-Si hybrid solar cells. Series resistance (R S ) extracted by the double diode model, contact quality explored by the Cox and Strack (CS) method, and the work function measured by ultraviolet photoelectron spectroscopy (UPS) revealed that the work function of the rear electrode effectively decreased after adding a metallic bilayer at the interface between Si and the rear electrode, which reduced the contact barrier, led to an Ohmic contact, and facilitated the transportation of electrons. Moreover, the minority carrier lifetime increased from 138.81 to 252.89 μs after applying a surfactant on top of the organic film because of the improved passivation effect. Remarkably, the best power conversion efficiency (PCE) of 14.40% for the dual bilayer planar solar cell is obtained, with a champion V OC of 656.4 mV. We provide an effective and facile strategy to design high efficiency with superior V OC by improving contact quality and passivation simultaneously in the Si-based solar cells.
