Abstract

Provided is a laminate with which an organic thin-film solar cell having excellent output characteristics, even in an LED light irradiation environment, can be obtained. A titanium oxide layer that serves as an electron transport layer and is positioned on a member that serves as an optically transparent electrode layer has a thickness of 1.0 nm to 60.0 nm, inclusive, and satisfies condition 1 or condition 2. Condition 1: The titanium oxide layer contains an indium metal and an indium oxide, wherein, if the content of elemental titanium is denoted as Ti, the content of the indium metal is denoted as InM, and the content of the indium oxide is denoted as InOx, the atomic ratio (InM/Ti) is 0.10 to 0.25, inclusive, and the atomic ratio (InOx/Ti) is 0.50 to 10.00, inclusive. Condition 2: The titanium oxide layer contains a tin metal and a tin oxide, wherein, if the content of the elemental titanium is denoted as Ti, the content of the tin metal is denoted as SnM, and the content of the tin oxide is denoted as SnOx, the atomic ratio (SnM/Ti) is 0.05 to 0.30, inclusive, and the atomic ratio (SnOx/Ti) is 0.50 to 10.00, inclusive.
