This study concerns a low-temperature method for dry hydrogen plasma reduction of inkjet-printed flexible graphene oxide (GO) electrodes, an approach compatible with processes envisaged for the manufacture of flexible electronics. The processing of GO to reduced graphene oxide (rGO) was performed in 1-64 s, and sp /sp +sp carbon concentration increased from approximately 20 % to 90 %. Since the plasma reduction was associated with an etching effect, the optimal reduction time occurred between 8 and 16 s. The surface showed good mechanical stability when deposited on polyethylene terephthalate flexible foils and significantly lower sheet resistance after plasma reduction. This method for dry plasma reduction could be important for large-area hydrogenation and reduction of GO flexible surfaces, with present and potential applications in a wide variety of emerging technologies.

“…After PEDOT:PSS coating, the reflectance of both planar Si and SiNWs samples decreases compared to the uncoated samples. In this case, the PEDOT:PSS could be acting as an antireflective coating to reduce the reflectance of Si layer as mentioned in previous reports [33,34]. After Gr is added, the reflectance of all samples is reduced about 3-5% compared to the samples coated PEDOT:PSS without Gr.…”

“…This is attributed to the low reflectance, the good carrier collection at the electrodes, and the effective carrier transportation in the nanowires [32]. The reduction of the reflectance by both the surface morphology and the Gr addition discussed in above section is a good issue that contributed to the increase of the PCE of solar cell [34,35]. The interaction between the Gr and PEDOT:PSS can provide additional charge transport pathways in hole transport layer and suppress the electron recombination at the junction interface [34].…”

We present the results on the effect of surface morphology and dispersion media on the properties of PEDOT:PSS/n-Si hybrid solar cell containing functionalized graphene (Gr). The hybrid solar cells based on SiNWs showed higher power conversion efficiency (PCE) compared to the planar based cells due to suppressing the carrier recombination and improving carrier transport efficiency. The PCE of hybrid solar cells could be improved by adding Gr into PEDOT:PSS. Different solvents including deionized (DI) water, ethylene glycol (EG), and isopropyl alcohol (IPA) were used as media for Gr dispersion. The best performance was obtained for the cell containing Gr dispersed in EG with a measured PCE of 7.33% and nearly 13% and 16% enhancement in comparison with the cells using Gr dispersed in IPA and DI water, respectively. The increase in PCE is attributed to improving the carrier-mobility, electrical conductivity, PEDOT crystallinity, and ordering.
