In dye sensitized solar cells (DSSCs), especially electrolyte parts, polymer gel electrolytes (PGE) has been attracted for many researchers because of their advantage in comparion with liquid electrolyte even though it has poor power conversion efficiency (PCE). We reports on quasi-solid state electrolytes forming ABA triblock copolymers which consist of styrene and ethylene oxide monomer unit. Not only introduced another copolymer which ethylene oxide`s molecular weight is different, but also changed copolymer`s added amounts, we could compare some effects of elements directly connected to PCE. We tried to experiment performance of DSSCs which the dye absorbed onto TiO2 paste was replacement with Z907 and D149 instead of N719 Ruthenium dye. Also, in order to check the barrier blocking effect of Co-adsorbent between the TiO2 and PGE interfacial surfaces, two DSSCs being with and without treated Co-adsorbent on the TiO2 paste were fabricated and measured by I-V simulator. |
