Abstract

Here a 2000-h light-soaking stability test is reported for cobalt complex based dye solar cells using Y123 organic dye with either platinum or poly(3,4-ethylene dioxythiophene) as counter electrode catalyst, and two different Co(III) electrolyte concentrations. Both the Co(III) concentration and the counter electrode catalyst affected the device stability. Higher Co(III) concentrations were found to slow down the degradation process with both catalyst materials. Different degradation behavior was also identified for devices with different catalyst materials.
