The introduction of graphene can effectively enhance the electrical conductivity, and improve the conducting stability of Al-doped zinc oxide (AZO) thin film upon bending. It is important to investigate the fabrication and optoelectronic properties of AZO/graphene/AZO sandwiched structure since it would remove technical barriers for the application of AZO thin film in flexible organic solar cell (FOSC).In this proposal, flexible thin film with AZO/graphene/AZO sandwiched structure is fabricated by using sputtering and chemical vapor deposition techniques. The relationship between preparation parameters, microscopic structure and conductivity, transmittance, conducting stability upon bending is studied. Emphasis is placed on the improvement mechanisms of electrical conductivity and bending conducting stability due to the introduction of graphene. The investigation of the device performance of FOSC based on AZO/graphene/AZO sandwiched thin film is carried out to study the effect of the presence of graphene on the power conversion efficiency of the FOSC, which reveals the application prospect of AZO/graphene/AZO sandwiched structure in FOSCs. The results provide theoretical and experimental bases for the understanding of preparation process, optoelectronic properties of the AZO/graphene/AZO sandwiched thin film, and the photovoltaic properties of the FOSCs based on the sandwiched thin film.
