Abstract： |
The present invention relates to a nano-crystal thin film and a low temperature preparation method. The thin film is provided with graded structure and uses nano-crystal titania particles of different sizes as raw materials to add specific chemical bonds or function masses to the surfaces of the nano-crystal particles through a method of surface modification. The materials are mixed in inorganic or organic solution to be prepared into carcass slurries before graded, which are made into films on a flexible conductive basement or any other basement through a simple film making method. Under a low reaction temperature, the particles in the thin films are well connected through chemical sintering, and the nano-crystal particles are connected through good chemical bonds. The whole thin film is provided with high mechanical strength. Flexible dye sensitization solar energy batteries, which are assembled from the thin films, are provided with the high photoelectric conversion efficiency. The thin film and the low temperature preparation method is predicated to be provided with a wide application prospect in photoelectric transformation and photo-catalyst fields. |
