First prototype

The woven photo-electrode

The TiO2 paste 18NR-AO purchased from Greatcell Solar is coated onto the mineral woven fabric provided by Isomatex by doctor-blade method. The fabric is then fired with conventional kitchen electric stove under 400˚C to 440˚C and it's soaked into annatto dyes for 5 hours after cooling down. The final piece appears in golden color after dyeing process is completed. The backside of the fabric is coated with silver paste (A729)
