Research Abstract |
Dielectric barrier discharge treatment and ultraviolet treatment were applied on titania photoelectrode of dye-sensitized solar cells (DSSCs). The treatments increased energy conversion efficiency of DSSCs by 35%. The treatments were also applied on titania paste on plastic substrate of DSSCs with 150 C sintering. Although the paste originally needs sintering at higher than 450 C, the resulting DSSCs shows as much as 80% energy conversion efficiency of that of glass substrate DSSCs fabricated using 450-C sintering.
