“…[32][33][34] In addition to its excellent electrical conductivity, its superior transparency (80-95%) in the visible range and satisfactory flexibility make it a good candidate to replace brittle and high cost indium tin oxide (ITO) as a transparent electrode in optoelectronic devices. And several research groups have reviewed its salient properties in optoelectronic devices from different viewpoints of applications such as organic and perovskite solar cells, [35][36][37] photoelectron spectroscopy, 38 organic light-emitting diodes 39 and electrode materials for supercapacitors. [40][41][42] Moreover, PEDOT:PSS is a promising organic thermoelectric material due to its advantages of good thermoelectric properties (ZT B 0.42), ultra-low thermal conductivity, processability, non-toxicity and unique flexibility, compared with traditional inorganic thermoelectric materials.…”

“…[ 12,13 ] Among all the organic materials, poly(3,4‐ethylene dioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) is widely used in the fabrication of solar cells based on SiNW/organic structure. [ 14–19 ] Recently, several studies have been carried out to improve the working stability of solar cell with temperature, humidity, and reduce the degradation of organic materials as well as increase the uniform of a conductive polymer layer on the Si substrate by employing carbon nanotubes, fullerenes, graphene oxide as additive materials. [ 20–27 ] Graphene has excellent properties such as low impedance, high transmittance, good mechanical properties, high thermal stability, and chemical stability.…”

Solar energy is considered as a potential alternative energy source. The solar cell is classified into three main types: i) solar cells based on bulk silicon materials (monocrystalline, polycrystalline), ii) thin‐film solar cells (CIGS, CdTe, DSSC, etc.), and iii) solar cells based on nanostructures and nanomaterials. Nowadays, commercial solar cells are usually made by bulk silicon material, which requires not only high fabrication costs but also limited performance. In this study, the fabrication of high‐performance solar cells based on hybrid structure of silicon nanowires/poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate)/graphene (SiNW/PEDOT:PSS/Gr) is focused upon. SiNWs with different lengths of 125, 400, 800 nm, and 2 µm are fabricated by a metal‐assisted chemical etching method, and their influence on the performance of the hybrid solar cells is studied and investigated. The experimental results indicate that the suitable SiNW length for the fabrication of the hybrid solar cells is about 400 nm and the best power conversion efficiency obtained is about 9.05%, which is about 2.1 times higher than that of the planar Si solar cell.

“…The most popular modification methods were solvent treatment [6,[12][13][14] and addition of nanomaterials [15][16][17]. Considering the bare Si substrate was directly covered by PEDOT:PSS film for original cell structure, two major problems are introduced, i.e., the defects on Si surface are not passivated and the interface contact between PEDOT:PSS film and Si substrate is poor [18]. To solve the problems, a thin interface layer was introduced.…”

Si/PEDOT: PSS solar cell is an optional photovoltaic device owing to its promising high photovoltaic conversion efficiency (PCE) and economic manufacture process. In this work, dopamine@graphene was firstly introduced between the silicon substrate and PEDOT:PSS film for Si/PEDOT: PSS solar cell. The dopamine@graphene was proved to be effective in improving the PCE, and the influence of mechanical properties of dopamine@graphene on solar cell performance was revealed. When dopamine@graphene was incorporated into the cell preparation, the antireflection ability of the cell was enhanced within the wavelength range of 300~450 and 650~1100 nm. The enhanced antireflection ability would benefit amount of the photon-generated carriers. The electrochemical impedance spectra test revealed that the introduction of dopamine@graphene could facilitate the separation of carriers and improve the junction quality. Thus, the short-circuit current density and fill factor were both promoted, which led to the improved PCE. Meanwhile, the influence of graphene concentration on device performances was also investigated. The photovoltaic conversion efficiency would be promoted from 11.06% to 13.15% when dopamine@graphene solution with concentration 1.5 mg/mL was applied. The achievements of this study showed that the dopamine@graphene composites could be an useful materials for high-performance Si/PEDOT:PSS solar cells.
