Elektrolytzusammensetzung für photoelektrochemische Zellen

摘要

An electrolyte composition comprises a compound represented by the following general formula (1): wherein Q represents an atomic group forming an aromatic cation having a 5- or 6-membered ring structure with a nitrogen atom; L11 represents a divalent linking group selected from the group consisting of a substituted or unsubstituted alkylene group, a substituted or unsubstituted alkenylene group, a substituted or unsubstituted alkylenoxy group, a substituted or unsubstituted alkenylenoxy group, and a repetition or combination thereof; R11 represents a hydrogen atom or a substituent; R12 represents a substituent; n1 represents 0 or an integer of 1 to the maximum number of R12 attachable to Q; X<-> represents an anion; R12's may be the same or different groups when nl is 2 or more; two or more of R11 and R12 may be bonded together to form a ring; and at least one of R11 and R12 contains a silicon atom. A photoelectric conversion device and a photo-electrochemical cell comprising the electrolyte composition are also provided.
