Method of manufacturing photovoltaic cell

摘要

Provided is a method for manufacturing a photovoltaic cell in which a light absorption layer is formed by promoting chalcogenation. The method includes providing a microporous member, arranging an object on a first side of the microporous member, and arranging a chalcogen source on a second side of the microporous member opposite to the first side, heating the chalcogen source, transmitting a liquefied or evaporated portion of the heated chalcogen source through the microporous member, and exposing the object to the liquefied or evaporated portion of the heated chalcogen source that has passed through the microporous member.

1. A method of manufacturing a photovoltaic cell, the method comprising:
providing a microporous member having micropores; arranging an object on a first side of the microporous member; arranging a chalcogen source on a second side of the microporous member opposite to the first side; heating the chalcogen source to liquefy the chalcogen source; providing the chalcogen source that has been liquefied to the micropores; retaining the liquefied chalcogen source at an upper portion of the microporous member to evaporate a portion of the liquefied chalcogen source and obtain a chalcogen gas; and exposing the object to the chalcogen gas exiting from a lower portion of the microporous member, the chalcogen gas having traveled through the micropores, wherein the micropores are large enough to allow the chalcogen gas to flow through the micropores but small enough to prevent the liquefied chalcogen source from flowing through the micropores.
