Electrochemical Impedance Analysis for Corrosion on Current Collecting Electrodes in Dye-sensitised Solar

Dye-sensitized solar cell (DSC) is paid attention to next generation’s energy device because of various advantages such as simple manufacturing process, low cost and low environmental loading1. Recently, the modularization technology has been developed for improvement of the DSC performance. For example, Toyoda et al.2 fabricated large scale DSC modules with glass substrate, and indicated that the modules have the long term stability for a half year. Itagaki et al.3 reported that a plastic DSC module maintained its high conversion efficiency under the accelerated condition of 55 ºC and 95 % relative humidity. Typical plastic DSC module is composed of three parts shown as follows4: (1) Photoelectrode (anode) which consists of a porou
