Document Type and Number:
WIPO Patent Application WO/2018/062307
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a flexible solar cell which has high high-temperature high-humidity durability and excellent initial performance. The present invention is a flexible solar cell (1) which comprises, on a flexible substrate (2), an electrode (3), a transparent electrode (4) and a photoelectric conversion layer (5) that is arranged between the electrode (3) and the transparent electrode (4). This flexible solar cell (1) is configured such that: the photoelectric conversion layer (5) contains an organic-inorganic perovskite compound; the flexible substrate (2) comprises an aluminum foil (6) and an aluminum oxide coating film (7) that is formed on the aluminum foil (6); and the proportion of the thickness of the aluminum oxide coating film (7) relative to the total thickness of the aluminum foil (6) and the aluminum oxide coating film (7) is from 0.1% to 15% (inclusive).
