In this paper, eight dye sentisized solar cells were made and their photo-induced voltage was measured under artificial lighting. Two electrolytes were prepared, one liquid in which I 2 and KI were dissolved in ethylene glycol, and the other a gel electrolyte prepared from polyethylene glycol. All eight cells of the photoanode use a porous layer of nanocrystalline TiO 2 , which was prepared as a paste applied to conductive slides using the "Blade" method. The paste was prepared using TiO 2 nanopowder that was dispersed in diluted acetic acid and deionized water with the addition of nonionic dispersant Triton-X 100. Thin layers of nanocrystalline oxide were processed in a laboratory dryer and then heated in a laboratory oven. Four dry glass slides were calcinated at 400 °C, while the other four were calcinated at a temperature of 450 °C. These thermally processed glass slides were immersed for 24 hours in an anthocyanin solution, obtained from dried hibiscus flower. The cathode of the solar cell was prepared by sputtering a conductive graphite layer onto eight glass slides, which were then dried so the organic solvent evaporates. Photovoltaic cells were assembled so that two cells processed at a temperature of 400 °C were made with liquid electrolyte, and the other two with gel electrolyte. The other four cells processed at a temperature of 450 °C were also assembled so that two had liquid and the other two gel electrolytes. From the results, it can be seen that the cells that used the gel electrolyte showed a much better longevity compared to the cells with the liquid electrolyte, even with the addition of new amounts of liquid electrolyte.
