Drying holder for solar cell and method for producing solar cell
View Patent ↗A drying holder holds a solar cell in an upright state, and is used in an electrode drying process. The drying holder is provided with a base part on which the solar cell is placed, and a support part that is disposed on the base part, and forms a support slot that is capable of accommodating the solar cell. Vents are formed on the base part and/or the support part.
1. A method of producing a solar cell, the method comprising:
providing a drying apparatus comprising a plurality of drying holders and a conveyor connecting the plurality of drying holders, wherein a support part of the drying holder comprises a pair of support units that are disposed away, each of the pair of support units has a sidewall that extends along a short-side direction of the rectangular base part, and two main walls that extend from edges of the sidewall along a direction crossing the sidewall, and an opening is formed by the sidewall and the two main walls, the support part is placed in such a manner that the openings oppose each other, and vents are formed on the two main walls facing a surface of the solar cell, in the drying the solar cell, an air flow is introduced into the support slot from vents formed on the pair of main walls, and each of the surfaces of the solar cell facing the main walls is a surface on which an electrode is formed,
drying a solar cell with the drying apparatus, the drying the solar cell comprising:
placing the solar cell on a rectangular base part of a drying holder of the plurality of drying holders; and
setting the solar cell in an upright state using the support part.
2. The method for producing a solar cell according to claim 1 , wherein
one of the pair of main walls is inclined such that an angle formed with the base part to the support slot side becomes an obtuse angle, and
the air flow is introduced into the support slot from the vents formed on the pair of main walls.
3. The method for producing a solar cell according to claim 1 , wherein the solar cell is dried in a state where the solar cell contacts one of the main walls.
4. The method of producing a solar cell according to claim 1 , wherein the main wall has a surface facing a direction of movement of the conveyor.
5. The method of producing a solar cell according to claim 1 , wherein
the main walls comprise a front-side main wall and a backside main wall; and
an opening area formed on the backside main wall is larger than an opening area formed on the front-side main wall.
