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.
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.
Emissive charge-transfer states at the hybrid organic–inorganic interface of C60 and CuSCN can be controlled by solution treatment.
