The invention discloses an all-solid-state optical thin film with adjustable transmittance, the all-solid-state optical thin film comprises a micro-heating layer, a first reflecting layer, a functional layer and a second reflecting layer which are sequentially arranged from bottom to top, and the invention further provides a preparation method and application of the all-solid-state optical thin film with adjustable transmittance. The all-solid-state optical thin film with the adjustable transmittance is stable in performance and low in energy consumption, the original state can be kept unchanged when no external excitation exists, and continuous power supply is not needed. 本发明公开了一种全固态透过率可调的光学薄膜，包括从下到上依次设置的微加热层、第一反射层、功能层和第二反射层，本发明还提供了全固态透过率可调的光学薄膜的制备方法和应用，与现有技术相比，本发明全固态透过率可调的光学薄膜性能稳定，能耗少，无外部激励时可保持原状态不变，不需持续供电。
