BENYAMIN YARMAND1,*
Continual mesoporous TiO2 films doped with various tin contents were prepared by simple and cost effective spray pyrolysis method for application in photoanodes of dye-sensitized solar cells. The results indicated that the presence of tin ions in TiO2 lattice led to deterioration of anatase crystalline structure, increased light absorption in ultraviolet and visible regions and films’ enhanced specific surface area. Thus with doping 1.5 mol% tin, cell overall conversion efficiency increased 36% and reached to 5.65% which was due to electron production increment as a result of improved dye adsorption on film surface and enhanced electron injection to TiO2 conduction band as a result of reduction in its Fermi level..

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.
