This review highlights scalable coating strategies for flexible perovskite solar cells, discussing substrates, electrodes, low-temperature transport layers, encapsulation, and coating methods, along with key stability issues and future directions.
Various doping strategies have been explored to improve the properties of CuSCN and continue to enhance the performance of CuSCN-based electronic and photonic devices. The underlying mechanisms and technological advancements are summarized herein.
Thermally deposited CuSCN thin film is used for hole transport layer in inverted perovskite solar cells. The structural, electrochemical, optical, and morphological properties of films are characterized.
The interfacial degradation at the CuSCN/Au interface due to Au–Cu alloying can be improved by replacing Au with carbon electrodes, delivering high device stability under light illumination.
Flexible perovskite solar cells (F-PSCs) have an efficiency exceeding 25%, featuring both light weight and the advantage of roll-to-roll production. However, their mechanical stability is insufficient, which hinders their commercial application.
