Scientists in Germany and Switzerland have used metal-free plastic cathodes to replace expensive transparent conducting oxide-coated electrodes in dye-sensitised solar cells.
The team says that a record metal-free plastic cathode cell performance of 4.22% can be achieved at full sun, which is 27% less than the standard value of platinised transparent conducting oxide-coated electrodes, but at a fraction of the cost.
