Abstract
A buffer layer manufacturing method, including: a preparation step for preparing a reaction solution which includes a component (Z) of at least one kind of zinc source, a component (S) of at least one kind of sulfur source, a component (C) of at least one kind of citrate compound, a component (N) of at least one kind selected from the group consisting of ammonia and ammonium salt, and water, in which the concentration of the component (C) is 0.001 to 0.25M, the concentration of the component (N) is 0.001 to 0.40M, and the pH of the reaction solution before the start of reaction is 9.0 to 12.0; and a film forming step for forming a Zn compound layer consisting primarily of Zn(S, O) and/or Zn(S, O, OH) by a liquid phase method with a reaction temperature of 70 to 95° C.
