Transparent, conductive substrates are investigated for surface emissivity control for thermal space applications by means of reversible Ag electroplating. Transmittance and reflectance measurements are used to demonstrate change in mirror formation and de-formation during Ag deposition cycling in electrochemical cells. Ag was cycled consecutively over 1000 times on Pt-doped indium tin oxide (ITO) in gamma-butyrolactone (GBL) electrolyte, and it was determined that the ITO electrode was not stable for long term cycling, with electrode degradation and irreversible deposit buildup being observed on the working electrode. Other alternative IR transparent conductive electrodes were investigated for long term stability, in particular conductive diamond coated silicon cathodes and Ag mesh anodes. In addition, air free preparation of reversible electrochemical devices was shown to improve cycling behavior.
