We synthesized a TiO2-based nanotubes/nanoparticles composite structural film (NPNT film) using monodispersed nanotubes by doctor blade technique. The monodispersed nanotubes were prepared by potentiostatic anodization of Ti foil with subsequent ultrasonic dispersing. For a comparison, TiO2 nanoparticle film (NP film) and nanotube film (NT film) were also prepared in the same way. The NPNT film obtained obvious improved fill factor (FF) and total energy conversion efficiency ( η compared to tra ditional NP film. CCharge-transport mechanism in NPNT film are discussed: The introduced nanotube is used as “electron expressway” for high speed electron transport , which decrease electron transport resistance and thus produce marked ly en hanced FF and improved total energy conversion efficiency efficiency..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
