Insights into corrosion in dye solar cells

Autor: Miettunen, Kati, Etula, Jarkko, Saukkonen, Tapio, Jouttijärvi, Sami, Halme, Janne, Romu, Jyrki, Lund, Peter

The main issue in using low cost metals in dye solar cells is the corrosion caused by the liquid electrolyte. Contrary to typical applications of metals, the adverse effects of corrosion in dye solar cells are related to irreversible depletion of cha

Publikováno v: Leinonen, H, Pohjanne, P, Saukkonen, T, Schildt, T, Romu, J & Hänninen, H 2011, Effect of selective dissolution on stress corrosion cracking susceptibility of austenitic and duplex stainless steels in alkaline solutions . in Proceedings : Corrosion 2011, Conference & Expo . vol. 2, 11160, National Association of Corrosion Engineers (NACE), Houston, TX, Corrosion 2011, Conference & Expo , Houston, TX, United States, 13/03/11 . < https://www.onepetro.org/conference-paper/NACE-11160 >

The formation of nickel-rich layers on austenitic stainless steels in strong caustic solutions was reported in 1970's. Recently, a more detailed study has shown the nature of the de-alloying process and established firm links with the other metal-env
