Different counter electrode (CE) materials based on carbon and Cu2S were prepared for the application in CdS and CdSe quantum dot-sensitized solar cells (QDSSCs). The CEs were prepared using low-cost and facile methods. Platinum was used as the reference CE material to compare the performances of the other materials. While carbon-based materials produced(More)
Gel polymer electrolytes (GPEs) consisting of polyvinyl alcohol (PVA) and double iodide salts have been prepared using ethylene carbonate (EC) and propylene carbonate (PC). Potassium iodide (KI) and tetramethylammonium iodide (TMAI) were used as mixed salts for making the electrolyte ion conducting. The highest room temperature (298K) conductivity of 12.91(More)
A binary salt system utilizing lithium iodide (LiI) as the auxiliary component has been introduced to the N-phthaloylchitosan (PhCh) based gel polymer electrolyte consisting of ethylene carbonate (EC), dimethylformamide (DMF), tetrapropylammonium iodide (TPAI), and iodine (I2) in order to improve the performance of dye-sensitized solar cell (DSSC) with(More)
