Method for manufacturing device comprising inorganic/organic hybrid perovskite compound film and device comprising inorganic/organic hybrid perovskite compound film

A laminate for manufacturing a solar cell having a tandem structure comprising:

• a first structure including a first substrate which is a transparent substrate, a first electrode which is a transparent electrode positioned on the first substrate, a charge transport structure positioned on the first electrode, and a first surface layer containing at least one of materials i) to v) below, and
• a second structure including a second electrode, an inorganic light absorbing layer that is positioned on the second electrode and absorbs light of 800 nm or more to generate electrons and holes, a bonding layer positioned on the inorganic light absorbing layer, and a second surface layer containing, independently from the first surface layer, at least one of the materials i) to v) below,
• wherein the laminate is a laminate in which the first structure and the second structure are stacked so that the first surface layer of the first structure and the second surface layer of the second structure are in contact with each other,
• wherein the first surface layer and the second surface layer are each independently formed of a coating film on which a particulate of at least one of the materials i) to v) is coated, a porous film of at least one of the materials i) to v), a dense film of at least one of the materials i) to v), or a combination thereof of
• i) an inorganic/organic hybrid perovskite compound,
• ii) an organic halide,
• iii) a metal halide,
• iv) an inorganic/organic hybrid perovskite compound precursor, and
• v) a metal halide precursor.
