Abstract

A laminate including a member that serves as a light-transmissive electrode layer and a zinc oxide layer that serves as an electron transport layer for an organic thin-film solar cell is provided. The zinc oxide layer has a Zn deposition amount of not less than 20.0 mg/mand not more than 120.0 mg/m. An S value represented by Formula (1) is not more than 0.90 when, in the zinc oxide layer, an oxygen 1s spectrum obtained by X-ray photoelectron spectroscopy is separated into three peaks, an area of a peak in which a binding energy of a peak top is in a range of not less than 529.0 eV and less than 530.7 eV is represented by α, and an area of a peak in which a binding energy of a peak top is in a range of not less than 530.7 eV and less than 532.2 eV is represented as β:
