Bubble Template

We prepare transparent, selfassembled polygonal silver nanowire (AgNW) mesh by bubble template and use as top electrode for a poly (3,4ethylenedioxythiophene):poly(stylenesulfonate) (PEDOT:PSS)/n-Si hybrid solar cell. Devices were fabricated by pressing the self-assembled AgNW and ITO electrodes onto the surface of the PEDOT:PSS and device performances were compared. In identical transmittances of ITO and self-assembled AgNW (i.e., 87% transmittance at wavelength of 550 nm), the self-assembled AgNW mesh electrodes shows lower sheet resistance (8 Ω/square) with enhanced transparency in the ultraviolet and infrared regions. As a result, a device performance with an efficiency of 9.60% was obtained with the self-assembled electrode compared to 9.07% efficiency from the indium–tin oxide (ITO) electrode under 100 mW/cm2 of AM 1.5 illumination. This study suggests the potential application of a self-assembled AgNW electrode as the transparent conducting electrode for future optoelectronic devices.

New Generation

Transparent conducting electrodes (TCEs) play a vital role for the fabrication of solar cells and pivoted almost 50% of the total cost. Recently several materials have been identified as TCEs in solar cell applications. Still, indium tin oxide (ITO) based TCEs have dominated the market due to their outstanding optical transparency and electrical conductivity. However, inadequate availability of indium has increased the price of ITO based TCEs, which attracts the researchers to find alternative materials to make solar technology economical. In this regard, various kinds of conducting materials are available and synthesized worldwide with high electrical conductivity and optical transparency in order to find alternative to ITO based electrodes. Especially, new generation nanomaterials have opened a new window for the fabrication of cost effective TCEs. Carbon nanomaterials such as graphene, carbon nanotubes (CNTs), metal nanowires (MNWs) and metal mesh (MMs) based electrodes especially attracted the scientific community for fabrication of low cost photovoltaic devices. In addition to it, various conducting polymers such as poly (3, 4-ethylene dioxythiophene): poly (styrenesulfonate) (PEDOT:PSS) based TCEs have also showed their candidacy as an alternative to ITO based TCEs. Thus, the present chapter gives an overview on materials available for the TCEs and their possible use in the field of solar cell technology

A bulk-heterjunction hybrid solar cell based on CdS nanorods as electron acceptor and conjugated polymers P3HT (Poly (3-Hexylthiophene)) as donor was fabricated through solution processing. Plasmon-active silver nanoparticle layers were introduced in the hybrid solar cell. Silver nanoparticle layers were fabricated using thermal evaporation deposition of 10 nm of silver thin layers on indium tin oxide (ITO) substrate followed by annealing. Under the surface plasmon excitation in Ag nanoparticles deposited on a semiconductor surface, increasing optical electrical field inside the photoactive layer led to an increased short circuit current density (Jsc) and improved fill factor (FF) of the cell. Consequently, under AM1.5G illumination (100 mW.cm-2), the plasmon-decorated cell based on CdS-nanorods/P3HT showed a four-times increase of the power conversion efficiency (PCE) compared with the undecorated one.

Filler Layer

Nanostructured metal mesh structures demonstrating excellent conductivity and high transparency are one of the promising transparent conducting electrode (TCE) alternatives for indium tin oxide (ITO). Often, these metal nanostructures are to be employed as hybrids along with a conducting filler layer to collect charge carriers from the network voids and to minimize current and voltage losses. The influence of filler layers on dictating the extent of such ohmic loss is complex. Here, we used a general numerical model to correlate the sheet resistance of the filler, lateral charge transport distance in network voids, metal mesh line width and ohmic losses in optoelectronic devices. To verify this correlation, we prepared gold or copper network electrodes with different line widths and different filler layers, and applied them as TCEs in perovskite solar cells. We show that the photovoltaic parameters scale with the hybrid metal network TCE properties and an Au-network or Cu-network with aluminum-doped zinc oxide (AZO) filler can replace ITO very well, validating our theoretical predictions. Thus, the proposed model could be employed to select an appropriate filler layer for a specific metal mesh electrode geometry and dimensions to overcome the possible ohmic losses in optoelectronic devices.

A single hybrid solar cell (SHSC) which consist of zinc oxide (ZnO) micro-rod and Poly (3-dodecylthiophene)(P3DDT) materials with nature dye from Melastomamalabathricum fruit (Mm) were fabricated to determine it electrical properties and power conversion efficiency (PCE). The ZnO microrod was growth by thermal method. P3DT was synthesis by oxidation polymerization method. Nature dye was extracted from Mm fruit in purplecolor.The fabrication of a SHSC started with growth ZnO microrodon the Indium Tin Oxide (ITO) in thin filmform, followed with P3DT layers and finally layered with Mm in 5 layers and 10 layers respectively.The SHSC wascharacterized the electrical conductivity and PCE also compared under dark condition and various light intensity. The conductivity of the samples is increase within the increment of light intensity and the efficiency of SHSC increase within the increment of layer of Mm. The highest electrical conductivity was for 10 layers of dye which is 2.678 + 0.002 Scm-1. The power conversion efficiency (PCE) of the ITO/ZnO/P3DDT/10 layers dye achieved was the highest which is 0.0011% under radiation of 200 Wm-2 intensity of light. As a conclusion, it can say that the amount of Mm can affect the performance of hybrid solar cell, where the dye is increased, the electrical conductivity and the PCE also increase. Thus, the Mm is a good dye and can be potential to apply in the solar cell.

Silver nanowire (Ag NW) networks are gaining more interest as promising candidates for the substitution of indium tin oxide (ITO) for top electrodes in optoelectronic devices. In this work we investigated the electrical, optical, structural, and morphological properties of SnO2/Ag NW hybrid film deposited by spray pyrolysis root. We showed that annealing at appropriate temperature improves optoelectronic and morphological properties of the SnO2/AgNWs electrodes; the optimal annealing temperature was 180 °C for 20 min. These annealing conditions allow better homogenization of the nanowires and their welding at the intersection nodes ensuring conduction of the charge carriers along the conductive grid formed of nanowires. The optimized SnO2/AgNWs electrodes have a large optical window covering the near-UV, Vis and IR range, with an average transparency of 85% and a sheet resistance of 6.1 Ω/sq. These optoelectronic performances have led to a merit factor of 2.5 × 10−2 Ω−1 being a competitive performance among the currently developed electrodes that can be promising candidates for applications as a transparent electrodes in optoelectronic devices.

Surface Plasmon Coupling

Silver nanowire (Ag NWs) networks with high transparency and low resistivity are widely used as promising candidates for the replacement of indium tin oxide (ITO)-based transparent conducting oxides (TCOs) in light-emitting diodes (LEDs). However, LEDs with Ag NW electrodes are less efficient than those with ITO electrodes because of their low electrical properties, such as high contact resistance and strong absorption in the visible region. In this work, we tried to improve the efficiency of LEDs with transparent conducting electrodes of Ag NWs networks via localized surface plasmons (LSPs) by adopting silver nanoparticles. We studied the effect of the thickness of the p-GaN layer on surface plasmon coupling. When a 45 nm thick p-GaN layer was used, the internal quantum efficiency was improved by LSP coupling between a dipole of QW and Ag NW/NP, and the light extraction was improved because the NPs afforded a leakage mode and acted as scattering centers.
