A step-by-step heat treatment was applied to ruthenium-based N719 dye solution for its potential application in dye-sensitized solar cells (DSSCs). The effects were analyzed and compared with standard untreated devices. A significant increase in short circuit current density was observed by employing a step-by-step heating method for dye solution in DSSCs. This increase of Jsc is attributed to the...
A novel method was developed to convert the electro-catalytically inactive commercial WO3 and SnO2 into high efficient WO3−x and SnO2−x counter electrodes for dye sensitized solar cells (DSSs) to replace Pt. Both WO3 and SnO2 was treated with Urea with different Urea mass ratio concentrations and annealed under N2 environment at 500°C. The energy conversion efficiency (PEC) was significantly improved...
