- the manifold 11b is connected via piping to a tank (not shown) in which the coating liquid is stored, and the coating liquid sent from the tank to the manifold 11b by a pump (not shown) spreads in the Y-axis direction within the manifold 11b. It is discharged from the discharge port 11a through the slit 11c. As a result, the coating liquid is discharged in a substantially uniform discharge amount along the Y-axis direction.

Then, when the substrate W is placed in the reduced pressure space, the pressure in the reduced pressure space 25a is reduced, so that the boiling point of the solvent in the coating film M on the substrate W is lowered, and the solvent is volatilized. That is, the coating film M is dried under reduced pressure within the reduced pressure chamber 25.

- the vacuum drying section 22 is also referred to as a first drying section, and the process of drying the coating film M by this vacuum drying section 22 is referred to as a first drying process.
- a phenomenon in which perovskite crystal nuclei are formed (increased) in the coating film M mainly occurs by volatilizing the solvent of the coating film M under conditions below a predetermined temperature (for example, 130°C). The longer the drying time, the more crystal nuclei are formed within the coating film M. Therefore, in this description, the first drying step is also referred to as a crystal nucleation step.
- the heating drying unit 23 is a device for baking the coating film M dried under reduced pressure by the reduced pressure drying unit 22 to obtain a perovskite film P, and includes a stage 28 on which the substrate W is placed and a heater 29 that heats the stage 28. are doing.

- the crystal state confirmation unit 3 includes a light source 31, a spectrum detector 32, and a stage 33, and irradiates the perovskite film P on the substrate W held on the stage 33 with light 34 from the light source 31 to detect the perovskite film.
- a spectrum detector 32 captures the light 34 reflected by P and performs a measurement.
- the result data measured by the spectrum detector 32 is transmitted via a cable 36 to a storage device 35 .
- the stage 33 has a substrate holding surface that is a horizontal surface on which the outer peripheral portion of the substrate W is placed, and the inside of this substrate holding surface is hollow when viewed in the vertical direction.
- This substrate holding surface is provided with a plurality of suction holes connected to a pressure reducing means (not shown), and when the pressure reducing means operates with the substrate W placed on the substrate holding surface, the stage 33 moves the substrate.
- the outer periphery of W is held by suction. Note that the substrate W is placed so that the surface of the substrate W opposite to the surface on which the perovskite film P is formed faces the substrate holding surface, so that the perovskite film P faces upward.
- the substrate W is held by suction.
- the light source 31 emits light 34 including light in a predetermined wavelength range from below toward the perovskite film P, and the light 34 emitted from the light source 31 passes through the cavity of the stage 33 and reaches the bottom surface of the substrate W. reach. The light 34 then passes through the substrate W and reaches the perovskite film P.
- the light source 31 and the spectrum detector 32 are arranged such that the light 34 emitted from the light source 31 passes through the substrate W and the perovskite film P and enters the spectrum detector 32. There is.

- information on the implementation conditions of the perovskite film P formation process measured by the spectrum detector 32 is also stored in advance in the storage device 35, and the upper and lower measurement result data and implementation conditions are stored in advance. A data group is formed.
- a computer equipped with this storage device 35 may be used to control the operation of each component of the film forming section 2 and the crystal state confirmation section 3.
- the photon energy hv is smaller than the band gap Eg, the light is not absorbed. Therefore, if the photon energy hv is smaller than the band gap Eg, the light is not absorbed. Therefore, if the light incident on the perovskite film P includes light in a predetermined wavelength range, and within that wavelength range there is a wavelength ⁇ that satisfies the following formula (1), then the light with a wavelength shorter than that ⁇ will become perovskite. Light that is absorbed by the film P and has a wavelength longer than ⁇ is not absorbed by the perovskite film P.
- the light 34 is emitted from the light source 31, reflected by the perovskite film P, and then made incident on the spectrum detector 32, thereby measuring the absorption spectrum.

- the band gap Eg of the perovskite film P changes depending on the crystal state of the perovskite film P (particularly the crystal size).
- the wavelength of the absorption edge also changes from equation (1). Therefore, if the crystal state is non-uniform within the perovskite film P, even if the wavelength of the absorption edge is ⁇ a at a certain position as shown by the solid line in Figure 2, at another position it is as shown by the chain line in Figure 2.
- the wavelength of the absorption edge is a wavelength ⁇ b different from the wavelength ⁇ a.
- the band gap Eg is a value that correlates with the power generation efficiency of the solar cell, and if the band gap Eg was non-uniform within the perovskite film P, the result of measuring the band gap Eg in a part would be good. Even so, there is a possibility that good power generation efficiency cannot be obtained for the perovskite film P as a whole, which is not preferable.
- the crystal state confirmation unit 3 determines whether the wavelength of the absorption edge is substantially uniform throughout the perovskite film P. This is confirmed by measurement. Specifically, the crystal state confirmation unit 3 measures absorption spectra at multiple points on the perovskite film P while moving the light source 31 and the spectrum detector 32 in the XY directions, thereby detecting the perovskite as shown in FIG. The absorption edge wavelengths at multiple measurement positions 37 throughout the film P are measured, and the obtained multiple absorption edge wavelengths (numerical data) are summarized as the numerical data distribution of the crystal state in the perovskite film P.

From this, it is expected that the crystalline state (crystal nucleus density) of the perovskite in the coating film M changes significantly in a short period of time in the vacuum drying process, compared to the conditions of heat drying (second drying). It is considered that the vacuum drying conditions greatly influence the size and density of the crystals in the final perovskite film P.

By doing so, the power generation efficiency of the perovskite film P at each measurement position can be easily grasped, as in the case of acquiring an absorption spectrum, and the condition adjustment step can be performed based on it.
- the conditions for forming the perovskite film P are adjusted so that the numerical data obtained in the subsequent crystal state confirmation steps will be approximately uniform over the entire perovskite film P.
- the conditions for forming the perovskite film P may be adjusted so that only the outer peripheral part of the perovskite film P has a different crystal state from the other parts.
- the air outlet of the air knife 21 is divided in the Y-axis direction so that the air volume and temperature of the drying air 24 can be adjusted individually, and the area where the substrate W of the stage 28 of the heating drying section 23 is placed is divided into small parts.
- the drying conditions may be made different for each small area of the perovskite film P by making it possible to individually adjust the heating temperature in each area.
