  • Method for forming a dye-sensitized solar cell having a porous film of an inorganic substance on a base material by spraying dry fine particles of an inorganic substance on the base material
    Patent number: 9721733
    Abstract: The present invention is a method for forming a porous film of an inorganic substance on a base material by spraying fine particles of an inorganic substance on the base material such that the fine particles are bonded to the base material and bonded to one another, in which the fine particles include at least two kinds of fine particles which are small-size particles and large-size particles having different average particle sizes. According to the present invention, it is possible to provide a film forming method for forming a porous film formed of an inorganic substance without requiring a baking step, a body having a film formed thereon that is produced by the film forming method, and a dye-sensitized solar cell including the body having a film formed thereon.
