Enhancement of photocurrent generation and open circuit voltage in dye-sensitized solar cells using Li+ trapping species in the gel electrolyte.

The influence of the addition of 12-crown-4 ether in a gel polymer electrolyte based to a PEO copolymer and its application in dye sensitized solar cells were investigated. Introduction of these Li+ trapping species brought beneficial contributions to both V(oc) and J(sc) values, increasing the device's performance.
