Quasi-solid dye sensitized solar cells using gel electrolytes

摘要

We investigate quasi-solid dye sensitized solar cells(DSC) using chemically crosslinked gels. Gel-electrolyte-precursors containing room-temperature molten salts and gelators are liquid at first. After they are injected in the cell, gels form in the cell by heating it at 80℃. The gelator was designed to make gels even in the presence of iodine which is an inhibitor for conventional gelators. The gelator is also designed so that gelation occurs by the addition of only 5wt% gelators by controlling the interaction between the gelators and the electrolytes. The quasi-solid DSCs exhibit high performances corresponding to those containing liquid electrolytes.
