Summary: Flexible solar cells have the potential to be an ideal power source for future electronic devices due to their compact structure and adaptable shape. However, the limited flexibility of these cells is caused by the delicate indium tin oxide-based transparent conductive substrates. In this study, a flexible transparent conductive substrate made of silver nanowires embedded in colorless polyimide was developed using a simple and effective transfer method. The resulting substrate showed a well-connected silver nanowire conductive network with low sheet resistance, high transmittance, and smooth morphology. The perovskite solar cells fabricated on this substrate exhibited high efficiency and maintained their initial efficiency after numerous bending cycles. This research highlights the importance of suspension modification for the distribution and connection of silver nanowires and opens up possibilities for high-performance flexible solar cells for practical applications.

Summary: Solution-processed silver nanowire (AgNW) networks, with excellent optoelectronic properties and low cost, are promising as next-generation transparent conductive electrodes. However, AgNWs are prone to fragmentation and degradation, and a protective coating is needed to improve their stability. This study presents a facile method using reduced graphene oxide to coat the AgNW network, resulting in improved transparency, resistance, and thermal and electrothermal stability. This approach represents an effective and low-cost strategy to enhance the overall operational resilience of metal nanowire-based transparent conductive electrodes.

Summary: Flexible transparent electrodes have been in high demand for touch panels, solar cells, and wearable electronics. Among the top choices is the silver nanowire (AgNW) flexible transparent electrode (FTE) due to its excellent light transmittance, flexibility, and highest conductivity among all metals. However, the large contact resistance has limited the conductivity of AgNWs network. By nanojoining AgNWs with graphene oxide (GO), the conductivity of the AgNWs network can be significantly improved, resulting in a low sheet resistance and high light transmittance for the AgNW-GO FTE.

Summary: The composite electrode with a graphene/silver nanowires/graphene sandwich structure shows high transparency and excellent conductivity improvement, making it promising for flexible, stretchable, and transparent electrodes. Research suggests that the high surface friction of the sandwich structure causes a sliding effect between the graphene layers, reducing crack or hole formation to maintain conductivity.
