PV Efficiency Improved Large-area Dye-sensitized Solar Cells
Several techniques including current-collecting metal fingers and double-layer TiO2 electrode were applied to improve the conversion efficiency of large area dye-sensitized solar cells (DSSCs). Silver paste was used to fabricate the current-collecting metal fingers on the fluorine-doped tin oxide (FTO) glass substrate by screen-printing process. Then a single-or double-layer TiO2 electrode was fabricated by using screen-printing process. The double-layer TiO2 electrode consists of a transparent TiO2 layer and a light-scattering TiO2 layer. Results showed that applying the current-collecting metal fingers and double-layer TiO2 electrode could effectively improve the conversion efficiency. The conversion efficiency of 5.89％ was achieved in a DSSC module with an area of 50mm 50mm by using the current-collecting metal finger cell of 45mm 3.5mm and double-layer TiO2 electrode under global air mass 1.5 condition.
