Summary: The electrical and electromechanical properties of hybrid graphene nanoplatelet (GNP)/carbon nanotube (CNT)-reinforced composites were analyzed under two different sonication conditions. The electrical conductivity increases with increasing nanofiller content, while the optimal sonication time decreases in a low viscosity medium. Samples with a higher GNP/CNT ratio show a higher prevalence of GNPs, with an exponential behavior of electrical resistance with applied strain and gauge factors reaching around 10.

Summary: Increasing the interfaces of carbon nanotube buckypaper improves its mechanical load transfer ability, but also increases contact resistance and retards the increase in electrical conductivity. Chemical functionalization, doping, and densifying have shown positive results but still fall short of the physical attributes of individual nanotubes. In this study, the amount of surfactant was controlled during the preparation of buckypaper to manipulate its mechanical and electrical properties. The prepared buckypapers exhibited high crystallinity and lower defects, and the interplay between surfactant and physical parameters affected the dispersion forces and interface contact among nanotubes. The buckypaper with the lowest surfactant content had the highest electrical conductivity (91.74 S/cm), which was twice that of the buckypaper with the highest surfactant content. Moreover, the tensile strength of the buckypaper showed a 104% improvement with the control of surfactant concentration, indicating the viability and importance of this study for further buckypaper development.

Summary: The properties of PEDOT:PSS have been improved by incorporating graphene oxide (GO), resulting in a high-efficiency hole transport layer (HTL) for PEDOT:PSS/n-Si hybrid solar cells (HSCs). The addition of a small amount of GO enhances the structural, electrical, and Si surface passivation properties of PEDOT:PSS, leading to improved photovoltaic performance of PEDOT:PSS-GO/n-Si HSCs. The study shows that the oxygen functional groups on the surface of 2D-GO sheets interact with PEDOT:PSS, significantly increasing its electrical conductivity by more than two times without impacting its optical properties. Additionally, the composite film effectively passivates the n-Si surface, resulting in a 1.7-fold increase in minority carrier lifetime. PEDOT:PSS-GO/n-Si HSCs achieved a highest power conversion efficiency (PCE) of 11.22% on a device dimension of 1 cm2, which is 4.14% higher than that of pristine PEDOT:PSS. This improvement is attributed to the enhanced charge transport properties of PEDOT:PSS-GO, interface passivation, and efficient separation and collection of photo-carriers with optimum GO addition. The study demonstrates that PEDOT:PSS-GO composite can be an effective HTL for efficient PEDOT:PSS/n-Si HSCs.
