New type gels for dye sensitized solar cells

In this thesis, newly synthesized gels were used as gel electrolite to solve the liquid electrolite problem at Dye Sensitized Solar Cells (DSSC). For this purpose, DSSCs were fabricated with Black Mulberry as a sensitizer. Seven DSSCs were fabricated. Then, one of them was prepared conventional iodine electrolite. The others were prepared with iodine electrolite adsorbed Poly (2- acrylamide- 2- methyl propaure sulfoute acid (itaconic acid/ N.N'methylene bi saerylawulde amice (Poly-AMPS-IA) and Fluorine (F), bromide (Br), Chlorine (Cl), Aniline (An), doped derivatives and solar cell parameters (efficiency, fill factor etc.) were investigated in terms of electrical stability of the DSSCs for 150 days. It has been found that DSSCs with above mentioned gels show stable electrical characteristic even for 150 days. Furthermore, it has been observed that used gels can dramatically improve solar cell energy conversion efficiency with the values of 2.62 fold for Poly (AMPS-IA/F-Cl-Br-An), 2.23 fold for AMPS-IA, 1,69 fold for AMPS-IA/An, 1.62 fold for AMPS-IA/Cl-An and 1.46 AMPS-IA/F-An, AMPS-IA/Br-An.
